Hi Paul
I asked Ian Shepherd about this - TC Steve is the 1st TC ever to be
renamed 3 times by each of the TC forecasting & warning centres.
It will be the 1st TC that has almost gone the loop - several have
gone close (Thelma for one - started North of Darwin, and ended up
giving Melbourne squally winds & rain If I remember...after
traversing the WA coast) but TC Steve is one of a kind..... he even
stuffed the weather here for a few days - taking the guts out of the
monsoon trough!
What an amazing little burts of instability! To just think how it
started ....... it boggles the mind that 1 parcel of air rising that
started the process has caused so much..........
Paul in Darwin
Ps Matt P went chasing today out to Kakadu (well he actually went
on a trip) but he would have had some great storms - been about 5
to the east most of the day.

Hi Blair,
Sargeant's book "Willy-Willies and Cock-Eyed Bobs" is a good eye opener
on Australian tornado climatology but with somewhat questionable facts.
Although S.C. Allen (A Preliminary Australian Tornado Climatology, 1980)
stated that 15 people died in a plane crash near Sydney Airport on 30
November 1961, the "official" cause of the crash as determined from an
official inquiry found that the cause was thunderstorm turbulence. However,
on this day there were numerous eyewitness accounts of funnels and roll
clouds associated with this storm. With questionable facts such as these, a
true accurate tornado deaths figure unfortunately cannot be calculated, only
estimated. I agree with you Blair that the 15 deaths in Sydney are very
questionable. I personally believe further investigating should be done
before releasing these figures to the public or any other source.
Deano

Very active, large, well fed cu are bubbling away over the ranges to the west of
Canberra
at 9.30am. Some strong radar echoes have already passed southwards to the west
and
some new cells seem to be developing around Wagga.
This could be a very interesting day....
(A slight negative is the fairly thick cirro-stratus
layer which will inhibit some convection - but hopefully not by too much.

Very nice report, Matt!
You know, there are probably a hundred different ways to do a surface
analysis. I took a look at the surface map and the other synoptic data
you included and it prompted a question.....
I wonder if the placement of the surface cold front on the surface synoptic
map leaves anyone else somewhat puzzled. I can see where I would place it,
admittedly not having seen any surface reports but rather using the
pressure analysis and the other information you provide. There does seem
to be a natural trough line/front extending through the 1012 and 1008
contours into central Australia. It would then likely pass north of Steve
and out to sea along the southern edge of the high pressure system.
Moreover, this would place Matt's storm in the vicinity of the surface
front, favorable low-level convergence, thermodynamic, and the upper level
supporting features, where one would normally expect.
I was going to ask what I was missing but it is clear I am missing a lot of
other data. Other reactions?

Les, I've started putting detailed synoptic charts, complete with
station plots, up on my site again -- go to
http://ausweather.simplenet.com/ and follow the links to Current &
Recent Synoptic Charts. The charts should print out nicely on
landscape format A4, after which you can play with a pencil to your
heart's content!
The maps are produced using massaged Bureau of Meteorology data and
Digital Atmosphere software. At present I am preparing them manually,
so it's not possible to be regular and timely in putting them on the
site. However, Tim Vasquez, the author of DA, is working on a scripted
version of DA which, coupled with my already automated data massaging
programs, would allow me to put up similar charts to this
automatically. Any feedback on the current charts would be
appreciated.

16 degrees at Blackheath(my place) at Midday with 3mm in the gauge.
Bit of a mop up yesterday/today with lots of small branches down (we had
a blackout Wed. night too from 8-9pm) and some trees down too.
It was interesting watching that low move south yesterday morning. At
8am on Blackheath station it was clear sunshine at the northern end of
the platform and overcast and misty to the south at the railway crossing
near Mitre 10.

Hi Les,
I'm even more puzzled by your comments. Surely you mean South of Steve and
along the Northern edge of the High?? But in fact the sat pics show cloud
associated with a trough system, which in Victoria is a pre-frontal trough.
It would be quite unusual for a cold front to continue as a MSLP feature as
far North you are suggesting at this time of year.
Regards,
>snip
There does seem
to be a natural trough line/front extending through the 1012 and 1008
contours into central Australia. It would then likely pass north of Steve
and out to sea along the southern edge of the high pressure system.
Moreover, this would place Matt's storm in the vicinity of the surface
front, favorable low-level convergence, thermodynamic, and the upper level
supporting features, where one would normally expect.
I was going to ask what I was missing but it is clear I am missing a lot of
other data. Other reactions?

as far as weather goes - there have been storms in southern NSW to the NW of
Albury all day - they aren't going anywhere and yes they really do
exist....Melbourne has Cu
and a few words from macca....."just had a look and there seems to be a cap
at about 6500-7000ft or so which is prohibiting development above that. Cap
is prolly going to weaken during the day but probably won't break down here.
More energy (from warmer temps and higher DP's) and weaker cap in the NE of
the state will cause/has caused it to break up there and the extra lift from
the ranges will help no end."
all I can say is, we have a long weekend...now all we need are the storms -
and from the BoM spokesperson on the radio this morning "there is a slight
risk that today might be fine...."

Just ignoring the maps a minute, the topography is very important too. All
the storms that day formed over higher ground, Lithgow itself is about 900m
above sea level, by US standards this is laughable, but it does make a
difference here. Lithgow is also the likely convergence point for winds off
the Tasman vs interior winds, and some lifting would occur.

MONTHLY GLOBAL TROPICAL CYCLONE SUMMARY
JANUARY, 2000
(For general comments about the nature of these summaries, as well as
information on how to download the tabular cyclone track files, see
the Author's Note at the end of this summary.)
NOTE: The January summary will be issued in two installments. This
first installment covers the Australian Region and the South Pacific.
The second installment, covering the Southwest Indian Ocean, will
hopefully be ready within a few days.
***********************************************************************
SPECIAL NOTE by the AUTHOR
I have been cranking out these summaries now for slightly over two
years, and from the beginning I have been overwhelmed by the reception
they have gotten from the tropical cyclone community--not only from
professional forecasters and researchers, but from those involved in
catastrophe modelling, insurance risk studies, emergency management,
etc, who have found material in the summaries useful to them, and also
from those who just have a keen interest in studying and following
tropical cyclones as a hobby. The time involved, however, spent in
constantly monitoring tropical cyclones, downloading warnings, and
preparing and proofreading the summaries is quite substantial; and,
considering that I have a long commute to work and am away from home
twelve hours every day, the task of writing the summaries becomes very
burdensome at times, especially during busy months.
In an attempt to continue keeping the summaries coming in the form
to which readers have become accustomed, I have enlisted the assistance
of some fellows in various countries who, like myself, have studied and
followed tropical cyclones for years and have a great interest in the
storms. A couple of guys, Matthew Saxby in Australia and Michael V.
Padua in the Philippines, limit their work to sending me tracking
information already typed in columnar format (which can require a
substantial effort in some months). Others, namely Patrick Hoareau
in France, Carl Smith in Australia, and John Wallace in Texas have
actually written some of the narratives for certain tropical cyclones
in recent months. Carl is currently writing reports for cyclones in
the Australian Region, and Patrick plans to assist with the North
Indian Ocean and at least some of the Northwest Pacific typhoons; and
if time permits, John Wallace will write the narrative sections for
Northeast Pacific tropical cyclones. Also, it should be mentioned
that Alipate Waqaicelua, Chief Forecaster of the Nadi, Fiji, Tropical
Cyclone Warning Centre sends me summaries and tracks for most South
Pacific tropical cyclones. I am very grateful to all these gentlemen
for their assistance (and also to many others who send me various
bits and pieces of information about tropical cyclones and their
effects).
That being said, it should be emphasized that I do carefully read
their contributions and edit as I see fit. Each one has his own
writing style with emphases on particular things, and I want their
individual personalities to shine through--in other words, I don't
want to edit and revise to the point everything sounds as if I had
written it. But I do try to insure that there is some consistency
and that the basic things I've always covered remain. No statement
gets through into the final product that I personally object to.
One other issue I'd like to address. The Atlantic and Northeast
Pacific basins are the only areas which essentially have only one
major TCWC issuing advisories/warnings. In all the other basins JTWC
issues official warnings for the U. S. Military Services and for the
benefit of any other parties who wish to use them. Also, with the
exception of the Australian Region, in the other basins there are
national meteorological services which issue warnings in addition to
the official RSMC and JTWC. From the beginning I have made
occasional comparisons between warnings from different warning agencies
when there were significant differences in position and/or intensity.
Analysis of tropical cyclone center positions and intensity by remote
sensing (satellite imagery) is often difficult and very subjective.
It is far from being an exact science. But I have always tried to
be objective in pointing out these to-be-expected discrepancies such
that there is no implied criticism of one TCWC over another, and this
rule likewise applies to any narratives written by my assistants.

AUSTRALIAN REGION (AUG) - From Longitude 90E Eastward to Longitude 160E
Activity for January: 2 tropical LOWs
1 hybrid LOW
1 severe tropical cyclone
The primary sources of information for Australian Region tropical
cyclones are the warnings and bulletins issued by the three TCWCs
at Perth, Darwin, and Brisbane. Information gleaned from JTWC's
warnings is used as a supplement for times when it was impossible to
obtain Australian bulletins and for comparison purposes. References
to sustained winds should be understood as being based on a 10-min
averaging period unless otherwise noted.
Matthew Saxby, a tropical cyclone enthusiast from Queanbeyan, New
South Wales, Australia, typed up the tracks for the cyclones and LOWs
in the Australian Region. Also, Carl Smith, another dedicated tropical
cyclone enthusiast from the Gold Coast of Queensland, authored the
narratives for Tropical Cyclones 06S and Kirrily. A very special
thanks to Matthew and Carl for their assistance.
A description of the Australian Cyclone Severity Scale can be found in
Chris Landsea's FAQ on HRD's website:
or on Michael Bath's Australian Severe Weather site:
Also, I performed some editing on Carl's write-ups. For anyone who is
interested in reading his complete cyclone reports, they are available
at the following URLs:
Australian Region Activity for January
--------------------------------------
Tropical cyclone activity in the Australian Region was somewhat on
the quiet side. Only one cyclone--Kirrily--was named, and this was
late in the month in the Southeast Indian Ocean off Western Australia.
Earlier there was a tropical LOW in the same region which persisted for
several days and eventually made landfall in Western Australia. JTWC
issued one warning of 35-kt winds with this system based upon a ship
report. Since Carl submitted a report on this LOW, I have included
it below.
There was a short-lived tropical LOW in the Coral Sea off the coast
of Queensland for which Brisbane issued a few warnings on 10 and 11
Jan. Gale-force winds to 35 kts were forecast for the southern
quadrant of the LOW at one point. There was also a gale center on 12
and 13 Jan well east of Brisbane which moved slowly westward toward
the southern Queensland coast. This system was likely a hybrid or
primarily baroclinic LOW. Tracks are given for these two systems in
the companion cyclone tracks file.
Additionally, there was an interesting example of a so-called
"landphoon"--a tropical LOW whose convective cloud signature seems to
improve even after it has moved over land. In mid-January a very weak
LOW formed near the coast of Western Australia and tracked southward
and inland. The maximum winds and minimum pressure when the system
was just off the coast were about 15-20 kts and 999 mb, respectively.
The cloud signature seemed to improve somewhat as the LOW moved
further inland over the Australian Outback. On Sunday, 16 Jan the
center passed just west of the Giles Meteorological Station (25.0 S,
128.3 E) and radar showed the circulation to be very weak.
Australia is one of the very few places where weak tropical LOWs
can drift inland and "appear" to intensify, even after they have
travelled well inland for a day or two. From a satellite perspective
these systems look like tropical storms, with persistent central
convection and a nice symmetrical pattern of cirrus outflow. It is
very possible that in the middle troposphere the circulation does
indeed intensify somewhat. From the standpoint of process, it seems
as if atmospheric conditions are extremely favorable for tropical
cyclone formation, and they do the best they can with land underneath.
(The above discussion was taken from some correspondence with Mark
Lander of the University of Guam and Andrew Tupper of BoM, Darwin.)
Tropical LOW (TC-06S)
18 - 23 January
----------------------
During the 3rd week of January, 2000, a tropical LOW formed in the
Gulf of Carpentaria, northwest of Weipa on Cape York Peninsula. It
drifted slowly west-northwestward into the Arafura Sea over the next
few days, passing to the north of Arnhem Land and Darwin.
By the 18th it had moved into the Timor Sea. BoM Darwin issued the
first shipping warning at 1200 UTC, indicating that a tropical LOW of
1000 mb was centred within 90 nm of 11.0 S, 127.5 E and moving west at
5 kts. Darwin continued issuing shipping warnings until 19/1200 UTC
when responsibility was handed over to BoM Perth as the system was by
then off the Kimberley Coast near 12.7 S, 125.3 E, moving southwest
at 10 kts.
Over the next couple of days the LOW continued moving southwestward
towards the Pilbara coast. JTWC issued the first TCFA on the 20th;
however, development was generally slower than either JTWC or Perth
expected, with JTWC issuing another TCFA later in the day.
Perth issued the first Tropical Cyclone Advice at 6:50am WST on the
21st (20/2250 UTC), stating that at 6:00am a tropical LOW was located
about 380 km (205 nm) north-northeast of Karratha and moving southwest
at 15 kts. The first cyclone warning was issued by JTWC at 21/0300
UTC, indicating that TC-06S had developed in the southeast Indian Ocean
about 350 nm northeast of Learmonth and was tracking southwestward at
10 kts within the steering flow of a subtropical ridge to the
southeast.
The 1st BoM warning for coastal communities was issued at 3:50pm
WST (0750 UTC) on the 21st for areas between Roebourne and Exmouth.
At 3:00pm (0700 UTC) the LOW with a CP of 1000 mb was estimated to be
about 290 km (155 nm) north-northwest of Karratha and moving south-
southwestward at 10 kts. At 21/0900 UTC JTWC noted that animated
satellite imagery indicated a rapid weakening of TC-06S, and animated
water vapour imagery revealed increasing vertical wind shear to the
southeast due to a mid-latitude trough and associated support of a
strong upper-level jet.
The difficulties JTWC had in tracking this marginal tropical cyclone
were revealed when it was relocated 60 nm to the east-northeast of the
previous warning position at 21/2100 UTC. The warning noted that the
system displayed a fully exposed LLCC with deep convection to the
southwest (based on DMSP night-time visible imagery), and animated
infrared satellite imagery depicted increasing convection over the
previous six hours.
Over the subsequent 24 hours TC-06S continued its west-southwestward
motion towards the Pilbara Coast, slowly deepening to 992 mb, but never
quite reaching tropical cyclone strength according to BoM criteria.
The only significant change was noted in a JTWC warning issued at
22/1500 UTC, which stated that, based on infrared satellite imagery,
the system had taken a turn to the southeast during the previous six
hours, and it appeared that the low/mid-level HIGH over the Western
Plateau had weakened and shifted further east than model guidance had
previously indicated, due primarily to the sudden eastward movement of
a mid-latitude trough which had been quasi-stationary off the southwest
coast of Australia. Water vapour imagery also indicated that the
trough had increased in amplitude.
The BoM issued its final warning on this system at 9:50am WST
(23/0150 UTC) on the 23rd, stating that the tropical LOW with a CP of
992 mb and wind gusts to 40 kts was, at 9:00am WST, estimated to be
about 70 km (40 nm) west-northwest of Port Hedland, moving south-
eastward at 14 kts. JTWC issued its final warning at 23/0300 UTC,
noting that the system was dissipating over land.
NOTE: JTWC only issued one warning (22/0600 UTC) estimating the 1-min
avg MSW at 35 kts. Satellite intensity estimates were 25 kts, but the
remarks indicated that there was a synoptic ship report of 35-kt winds
west of the center.
Severe Tropical Cyclone Kirrily (TC-09S)
25 January - 1 February
-----------------------------------------
A developing 1002-mb tropical LOW in the Indian Ocean southeast of
Christmas Island was first mentioned in an Australian Bureau of
Meteorology (BoM), Perth, shipping warning issued at 2157 UTC on
25 Jan when the LOW was centered about 250 nm southeast of Christmas
Island, moving east-southeastward at 11 kts. JTWC issued a Tropical
Cyclone Formation Alert (TCFA) at 26/2130 UTC with winds estimated to
be 25-30 kts. Satellite imagery at 1730 UTC indicated that a LLCC
was located about 400 nm north-northwest of Exmouth, Western Australia,
moving southeastward at 10 kts. Scatterometer data indicated a well-
defined LLCC associated with the convection and 200-mb analysis
indicated that the convection was slowly moving under the axis of an
upper-level ridge which would be expected to provide good outflow.
University of Wisconsin CIMSS Wind Shear charts also indicated
decreasing vertical shear in the path of the disturbance in the
direction of northwestern Australia.
The first tropical cyclone warning was issued by JTWC for TC-09S
at 27/0900 UTC. MSW (1-min) were estimated at 30 kts and the centre
was placed about 330 nm north-northwest of Learmonth, Western
Australia, moving south at 5 kts. Animated multi-spectral imagery
depicted new convection building over the LLCC and low-level cloud
lines were visible moving in toward the center from the southeast.
A mid-level HIGH situated over southwestern Western Australia was
forecast to build northwestward over the Kimberley region within
36 hours and should cause TC-09S to track initially south-
southeastward, then southwestward.
The LOW was named Kirrily by BoM Perth at 28/0016 UTC. The CP was
given as 985 mb and the 0000 UTC position was about 300 nm northwest
of Exmouth. Kirrily was moving southwestward at 6 kts and was causing
rough to very rough seas with moderate swell and 30-40 kt winds within
100 nm of the centre and winds to 50 kts within 30 nm of the centre.
The first public Tropical Cyclone Update was issued by Perth at 8:45am
WST (0045 UTC) on Friday, 28 Jan, stating that Kirrily, a Category 1
cyclone, was located about 295 nm northwest of Exmouth.
At 28/0600 UTC JTWC placed Kirrily's center about 325 nm northwest
of Exmouth, moving west at 9 kts with 55-kt winds (1-min avg). A TRMM
pass at 0314 UTC indicated that the system was developing an eye and
that convective banding was surrounding about 8/10 of the vortex. BoM
TC Update #2 at 2:30pm WST (0630 UTC) upgraded Kirrily to a
Category 2 cyclone that was moving southwestward at 6 kts. Only one
more public update was issued since it had become clear that Kirrily
posed no real threat to the Western Australian coastline.
At 29/0600 UTC JTWC placed Kirrily's center about 600 nm south-
southeast of Christmas Island, moving southwestward at 10 kts with
MSW (1-min) of 80 kts and sporting a 13-nm wide cloud-filled eye. A
minimum CP of 965 mb was estimated by Perth at 1100 UTC when Kirrily
was located approximately 625 nm south-southeast of Christmas Island.
The BoM warning indicated that winds to 65 kts were likely occurring
within 30 nm of Kirrily's centre.
By 1800 UTC JTWC had decreased its MSW estimate to 70 kts as the
cyclone continued to move to the southwest at 9 kts. Kirrily at this
time was located about 675 nm south of Christmas Island or about
470 nm west of Learmonth. Animated satellite imagery showed weakening
of the system and elongation to the southeast. A 29/1404 UTC SSM/I
pass indicated a very bload LLCC; however, convection was confined to
the very center and there was no longer any evidence of any type of
eye. A 200-mb analysis indicated that the upper-level ridge axis
remained south of the system and an upper-level jet was evident to the
southeast. Kirrily was tracking west-southwestward under the steering
influence of a mid-level subtropical ridge to the south and was moving
into an environment of increasing vertical shear.
Subsequent warnings issued by both centres indicated a continued
weakening trend, with the final BoM shipping warning being issued at
2225 UTC on 31 Jan. The weakening remnants of Tropical Cyclone
Kirrily with a CP of 999 mb were located about 750 nm south of
Christmas Island at 2200 UTC and were moving north-northwestward at
4 kts. Winds were forecast to ease below gale force within the next
three to six hours. The last warning was issued by JTWC at 2100 UTC
on 1 Feb with the MSW (1-min) estimated to be only 25 kts. Infrared
satellite imagery indicated a fully exposed LLCC which was moving
northwestward at 6 kts. The final JTWC warning placed the dissipating
centre about 625 nm west of Learmonth or about 700 nm south-southwest
of Christmas Island.
***********************************************************************
SOUTHWEST PACIFIC (SWP) - South Pacific Ocean East of Longitude 160E
Activity for January: 2 tropical depressions
2 tropical cyclones of storm intensity
Most of the information presented below was taken from the
operational warnings and advisories issued by the Fiji TCWC at Nadi.
References to sustained winds imply a 10-minute averaging period
unless otherwise noted. Also, the basic definition of a cyclone in
WMO Region 5 (Australia and the South Pacific) has the unique
requirement that a depression must have gale-force winds more-or-less
completely surrounding the center before the system is named as a
tropical cyclone. Hence, often gales of 35-40 kts may be present in
one or two quadrants but the system is not considered a tropical
cyclone. Last season Fiji initiated their own numbering scheme for
tropical disturbances (01F, 02F, etc) that form in the Nadi AOR.
Some of the numbered disturbances never warrant depression status.
The reports on Tropical Cyclones Iris and Jo were written by
Alipate Waqaicelua, Chief Forecaster at the Nadi TCWC, with only
minimal editing by myself. A very special thanks to Alipate for
sending me the summaries and the cyclone tracks. I wrote the
discussion on Tropical Depression 08F; also, I added some discussion
about the extreme Dvorak objective T-numbers generated for Tropical
Cyclone Iris.
Southwest Pacific Activity for January
--------------------------------------
January saw the formation of the first two South Pacific tropical
cyclones of the 1999-2000 season. In addition to Tropical Cyclones
Iris and Jo, there were a couple of systems carried in warnings from
Fiji as tropical depressions. One of these, TD-08F, persisted for
several days with associated gale-force winds, so I have included a
separate report on this system below. Another depression, TD-06F,
formed on 3 Jan near Vanuatu and moved slowly east-southeastward over
the next couple of days. The system formed and operated in a sheared
environment which did not allow it to strengthen. The depression
passed south of Fiji and had weakened just east of the Dateline by
6 Jan. A track is included for this system in the companion cyclone
tracks file. (A tropical disturbance numbered 07F was mentioned in
Nadi's Tropical Disturbance Summary on 16 Jan, located well to the
west-southwest of Tahiti. This disturbance subsequently dissipated
without being accorded depression status.)
Tropical Cyclone Iris (TC-05P / TC-05F)
7 - 10 January
----------------------------------------
A disturbance was first identified around 03/0600 UTC just north-
west of Espiritu Santo, in Vanuatu, embedded in a stationary monsoon
trough. The system was located under a moderately sheared environment
aloft, with slightly hostile conditions at lower levels. This
basically denied the system any chances for further development.
For another 36 hours, the system was subjected to shear and diurnal
influence, making it at times extremely difficult to locate the general
centre. However, after 06/0000 UTC, the outflow around the system
improved significantly with convection increasing and getting slightly
more organised. Twenty-four hours later, at 07/0000 UTC, convection
was getting better organised still, with the LLCC gradualy moving under
the western edge of the deep convection. Gale warnings were issued
but for certain sectors only. Overnight the depression, displaying
midget characteristics, intensified further under weakening shear
aloft. A compact CDO had also formed which was now moving southeast
at 5 kts.
The depression continued to develop under favourable conditions, and
at 07/2100 UTC was named Tropical Cyclone Iris while located about
180 nm northwest of Port Vila, moving southeast at 5 kts with an
intensity of 35 kts (10-min avg) and forecast to increase to 40 kts
during the next 6 to 12 hours. The cyclone was anticipated to track
more easterly under a westerly steering current. Six hours later, at
08/0000 UTC, winds around the compact centre were estimated to be about
45 kts. Gales were confined to within 60 nm of the centre. Iris
reached storm intensity at 08/0600 UTC while located about 130 nm
northwest of Port Vila, tracking east-southeastward at 8 kts. The
cyclone moved close to or over the island of Epi overnight, but its
compactness was quite evident as recorded winds over Vila, about 60 nm
due south, were only 15 to 20 kts. No damage reports could be
obtained from Vanuatu, but it is most likely that damage, if any,
would be minimal. This was despite an intensity of 60 kts at its
peak, which occurred around 08/1200 UTC.
Iris gradually accelerated eastward as it left Vanuatu, but always
tracking more and more south of east with time. The system was also
becoming more and more asymmetric as it moved closer to Fiji, evidence
of strengthening shear and environmental influence. After 09/0000 UTC,
the cyclone began its weakening trend. Intensity was down to a gale
18 hours later, at 09/1800 UTC, when it was located about 210 nm west-
southwest of Nadi and moving east-southeastward at 13 kts. After
10/0000 UTC, while only about 120 nm southwest of Nadi, Iris was
shunting east-southeastward at 15 to 20 kts into increasing shear
and cooler waters. The cyclone was downgraded to a depression 48 hours
after it had reached its peak intensity--the final warning placing
the centre on the Dateline about 150 nm southeast of Fiji.
Though it was expected that as the system weakened gales might
expand further out from the centre, only fresh to strong winds and very
rough seas with heavy swells were experienced over the western and
southern parts of Fiji. Once the system was named, the intensity curve
took a rate much steeper than any 'normal' cyclone. This was also the
case during the decay phase, though at a much gentler trend. Damage
in Fiji, if any, would have been either minimal or negligible.
JTWC's positions and 1-min avg MSW estimates agreed very well with
Nadi's for Tropical Cyclone Iris. The peak MSW (1-min) from JTWC
was 65 kts while the peak 10-min avg MSW estimated by Nadi was 60 kts.
However, Iris exhibited some features which hinted that the midget
cyclone could have been far more intense for a brief time than either
warning centre estimated. According to Dr. Mark Lander, T-numbers
obtained with the objective (digital) Dvorak method reached T6.5 or
slightly higher for a 4-hour period on 8 Jan from around 0230 to 0630
UTC. The Dvorak scale equates T6.5 with a MSW (1-min) of 127 kts or
a 10-min avg MSW of 112 kts. A satellite bulletin from JTWC at
08/0625 UTC assigned a T-number of 4.0, but the comments indicated
that there was a great inconsistency between the visible and infrared
methods with an IR-derived T-number of 6.0. These extreme T-numbers
persisted for only a short time, however. By 0915 UTC the eye had
disappeared and a JTWC satellite bulletin indicated that the system
had lost much convection over the past two hours.
Mark Lander further comments that such rapid strengthening followed
by rapid decay seems to be a common occurrence with very small, midget
tropical cyclones. They seem unable to remain at peak intensity for
very long--often for just a few hours--before beginning to fall apart.
Typhoons Ellie (1991) and Virgil (1999) were two recent NWP systems
which behaved the same way as Iris. No one will ever know just how
intense Iris became since the core of the small cyclone did not pass
over any weather station and of course there was no aerial
reconnaissance available.
Tropical Depression (TD-08F)
20 - 26 January
-----------------------------
A tropical disturbance was noted near Apia, Western Samoa, around
0600 UTC on 20 Jan. Over the next few days the system drifted slowly
southwestward and gradually became better organized. By 23/1800 UTC
the disturbance had become sufficently developed to be classed as a
tropical depression with the Fiji TCWC initiating gale warnings and
Tropical Disturbance Advisories. TD-08F was then located between
Fiji and the Kingdom of Tonga and displayed a CDO-type cloud pattern.
However, the system had moved south of the 250-mb subtropical ridge
and was being affected by increasing westerly and northwesterly shear.
The depression recurved to a southeasterly course and passed through
the southern Tongan islands on 24 Jan. At 24/0600 UTC the LLCC was
still exposed and the gale-force winds were confined to the south-
eastern semicircle. Six hours later the LLCC had moved closer to the
CDO feature and the cold cloud tops had increased in areal extent.
By 1800 UTC the LLCC was near the southwestern edge of the deepest
convection which had continued to increase in extent with cooling
cloud tops. The depression seems to have reached its peak organization
about this time but there was still evidence of fairly strong vertical
shearing. Gales were reported to be occurring within 40 nm of the
center from the north around the eastern side into the southwestern
quadrant of the system.
Thereafter the LLCC began to be sheared farther and farther away
from the convection as the depression continued to move southeastward
into a region of increasing vertical shear. By 26/0000 UTC the
system was entering Wellington's AOR, and gales were expanding in
area, indicating that extratropical transition was beginning.
Occasionally, in most tropical cyclone basins, poorly-organized
depressions will be seen with little deep central convection but with
peripheral gales on the poleward side due to a tight pressure gradient
with a neighboring area of high pressure. The basic definition of
a tropical cyclone in WMO Region 5 (Australia and the South Pacific)
contains the requirement that sustained gale-force winds should
surround the center before a developing depression is named as a
tropical cyclone. This criterion was ostensibly added to provide
some objective guidance for weeding out poorly-organized systems which
might contain gale-force winds but which do not have the appearance of
a typical, developing tropical cyclone.
In the case of TD-08F, the gales never surrounded the center, but
they were very close to the center--within 30-40 nm, based upon the
warnings from Nadi. In looking at the depression in some infrared
satellite imagery, to me it appeared to be similar to some sheared,
weak tropical storms which I've seen in the Atlantic; however, I do
not have available any Dvorak ratings on this system from any agency.
To my knowledge, NPMOC at Pearl Harbor did not issue any warnings or
alerts on this depression, which suggests that it was poorly organized
with only a very low potential for development.
Tropical Cyclone Jo (TC-07P / TC-09F)
23 - 28 January
--------------------------------------
A weak disturbance was first identified over the northern parts of
Vanuatu on the 19th, embedded in an active and slow-moving monsoon
trough. On the 20th the disturbance was located to the south of the
250-mb ridge with northwest winds of 40 kts to 55 kts above it.
Strong vertical shear had arrested development, which was also strongly
influenced by diurnal effects. However, atmospheric pressure at the
surface continued to gradually fall, but within a fairly broad area
surrounding the system. At 21/2100 UTC, a LLCC could be located by
satellite about 300 nm northeast of Port Vila in Vanuatu and about
340 nm northwest of Nadi in Fiji; hence, the upgrade to tropical
depression phase. The potential for development into a tropical
cyclone in the next 24 hours was still low as shear was still
significant over the system. However, on the 22nd shear was gradually
decreasing and pressure was also falling at a steeper rate. By the
23rd convection had significantly increased with slight improvement in
organisation. The depression was then located in a relatively weakly
divergent area at 250 mb; hence, at 22/2100 UTC the potential for this
depression to develop into a cyclone in the next 24 hours was assessed
to be moderate to high.
The first Tropical Disturbance Advisory on this system was issued
at 23/0000 UTC when it was centered about 460 nm northwest of Nadi and
expected to drift slowly southeastward. Deep convective tops were
cooling and organisation, as well as outflow, was continually
improving. Aloft, the depression was placed along the subtropical
ridge axis in a very favourable area for further intensification.
Gale warnings were also issued around this time, though over certain
sectors only. Overnight TD-09F continued to develop while moving
slowly southward, with cold spiral bands beginning to wrap around the
LLCC. At 24/0300 UTC the depression was named Tropical Cyclone Jo
with winds of 35 to 40 kts close to the centre, which was located about
240 nm west of Nadi. The cyclone was moving south-southeastward at
about 10 kts.
Tropical Cyclone Jo attained storm-force intensity 15 hours later,
at 24/1800 UTC, with gales spreading to within 80 nm of the centre.
Cold spiral bands were still wrapping tightly around the centre. Warm
air intrusion was quite evident on satellite imagery throughout most of
the life of Jo while inside Nadi's area of responsibility. This, to an
extent, made locating the LLCC a little difficult while also preventing
the system from attaining hurricane intensity. Jo's intensity peaked
around 26/0000 UTC, while it was situated about 350 nm south of Nadi,
with a MSW of 60 kts close to the centre. Gales gradually spread
out from the centre to about 180 nm in the southeast semi-circle and
to 150 nm elsewhere around 26/1200 UTC.
Jo's closest approach to Fiji on its way towards the southeast was
on 24 Jan when the centre was located about 240 nm to the west-
southwest. The system had originally been tracking more south-
southeastward but gradually turned to the southeast under a west to
northwest steering flow on the 25th. With gales fanning out more,
strong 10-minute average winds to 32 kts with gusts to 50 kts were
affecting the western parts of Fiji's largest island, Viti Levu, and
nearby islands to its south. Frequent squally rainbands lashed these
areas from late on the 24th until late on the 26th, inducing flash
flooding. There was no major river flooding reported. On the 25th
a building 500-mb ridge from the east prevented any closer approach of
Jo to Fiji. This ridge was basically responsible for keeping the
cyclone on its southeasterly track, entering Wellington's AOR around
26/1200 UTC. Wellington assumed primary responsibility for warnings
on Jo after this time. Tropical Cyclone Jo was finally declared
extratropical at 28/0600 UTC when located well over 1000 nm east of
New Zealand's North Island and a similar distance southwest of Tahiti.
No damage reports in Fiji have been received as yet. If any become
available later they will be reported in a future summary.
Position and intensity estimates by JTWC compared extremely well
with those from Nadi for Tropical Cyclone Jo. As was the case with
Tropical Cyclone Iris, JTWC's and Nadi's peak 1-min avg and 10-min
avg MSWs were 65 kts and 60 kts, respectively.

EXTRA FEATURE
In order to shorten the amount of typing in preparing the narrative
material, I have been in the habit of freely using abbreviations and
acronyms. I have tried to define most of these with the first usage
in a given summary, but I may have missed one now and then. Most of
these are probably understood by a majority of readers but perhaps a
few aren't clear to some. To remedy this I developed a Glossary of
Abbreviations and Acronyms which I included in the July, 1998 summary.
I will include this glossary from time to time, primarily in "lean"
months without a lot of tropical cyclone activity to cover. But if
anyone missed receiving it and wishes to obtain a copy, send me an
e-mail privately and I'll forward them a copy.
***********************************************************************
AUTHOR'S NOTE: This summary should be considered a very preliminary
overview of the tropical cyclones that occur in each month. The cyclone

The other factor at play that day was probably the existence of
a dry-line or moisture discontinuity rather than a cold front (or
temperature discontinuity).
>From Canberra's perspective - on the
wrong side of the dry-line - winds were a dry NW tending
W - I recall that dew-points fell off quite rapidly to
the west that day. Temperatures gradually increased to
the west - as would be expected at this time of year.
The storms, higher humidity and lower cloud bases were
clearly visible to the far NE.
Today (10/3/00) the thickening of the high level cirrus
has inhibited storm development. There are a few decent
cu around but it looks like the main action as Jane
has observed is going to happen further west.
An STA has been issued for the Riverina.

--------------------------------------------------------------------
Just ignoring the maps a minute, the topography is very important too. All
the storms that day formed over higher ground, Lithgow itself is about 900m
above sea level, by US standards this is laughable, but it does make a
difference here. Lithgow is also the likely convergence point for winds off
the Tasman vs interior winds, and some lifting would occur.

Minneapolis had a max/min of 21/15 yesterday and -2/-3 today.
I've seen more impressive than that, though. In 1989 Dallas had maxima
of +31 C and -8 C on successive days in February! I also arrived in
Denver in September 1993, 36 hours after a max of 34, to find snow
on the ground...
Amazing what a decent landmass extending into higher latitudes will
do. Even the narrow Patagonian landmass makes a difference; Buenos
Aires has winter mean temps not too far out of line with Sydney's,
but they get a few single-digit maxima most winters, and snow every
few years.

Hi Jane,
I would highly recommend that you spend lots of money! There are a lot
of cameras out there (ie. under $4-500) that IMHO are just no good for
weather photography.. i would class my camera as somewhere between cheap
and nasty, and good quality.. i take up to 100 pictures on any day with
decent weather, and the majority of the time i only get 10-15 images
that are worth keeping.. the main problem i have is the camera focusing
on the foreground, and leaving the background either blurred, or
terribly overexposed.. it also doesn't show the smaller features of
bases that make them look nice in real life..
An SLR would be the go - but of course they cost and arm and a leg..
Jason Bush from Western Australia has a great little camera - it's a
Kodak DC 120 - he paid around $1000 dollars for it in mid 1998 and it's
a great camera for weather photography!! I've seen pictures he's taken
(of distant anvils) that would never turn out with my camera..
I would also recommend buying a high quality brand - my AGFA camera has
already got major problems after only 2 months of use (mind you it's
under warranty - i'm just till winter to take it back :P).. if you're
anything like me and you take pictures of anything with vertical extent,
then the cheaper brands might not last as long..
Oh yeah, i would LOVE a zoom on my camera! There are just so many
situations where something would look better if you could just zoom in a
little bit..
I also have a 28mm lens on my camera - i would highly recommend buying
something with at least a 35mm or 50mm lens..
One more thing - i have a screen on the back of my camera where i can
view any image in the camera, either in thumbnail format or full size
picture (the screen would be about 1 1/2 by 2 inches or so).. which is
BRILLIANT when you're on a chase, and you run out of room on the camera!
You can scroll through the images and delete anything you want.. not
sure how many cameras have this feature - but it's certainly very handy
(especially when you're not sure if a picture will come out well - you
can just look at it on the screen and take another one if it looks
crap!)
I could go on and on.....

We had a thunderstorm go through here this
morning, Rutherglen, Victoria (40 km west of Wodonga) at 8am to 9am that
dumped 44mm of rain. More rain in one hour than we've had the previous
two months combined nearly. The local schools were flooded inside
apparently. I know the streets certainly were. Best gutter cleaning I've
seen for a while! Everyone noticed that it is un-usual here to get a
thunderstorm at that time of day and certainly to get dumped with that
much rain in that period of time. I drive a school bus to two local towns
and both had dry roads and both are only approx 15ks from here. Raining
again now (12.20pm). The storm moved in from the North-east which is
again abnormal, as they usual come from the west here. Catch ya,
Ross

You have to wear proper shoes, not white sneakers. Just dress nicely in a
pair of pants and a shirt., just found this out now.

I've been using a Fujifilm DX-10 with 64Mb flash RAM since Christmas, it's
had some halfway decent reviews in the UK photo / computing press. All the
images of the "mini - tornado" damage in Wallsend on Christmas Day (MSC
humour section - see for yourself) and the UK single cell action of the last
few weeks (ask if you want pix of single cell Cb in deep cold air UK style,
folks) have been taken with this baby.
I can also stick it out of the window and use it for timelapse jpeg video
with the PC as its got a video output.
Don't use them with standard alkaline batteries they don't last a day, I've
got a couple of sets of NiMH batteries and they last for weeks...
