Whoops! forgot the footer!
Hi All.
This just came in, I thought I would share it with you (See message pasted
below).
By my calculations:
If :
1 min mean max sustained wind (msw) in knots
x0.88 = 10 min msw kt
x1.853= 10 min msw km/hr
x1.4= max gusts km/hr
Then:
127 knot 1 min sustained = 111kt 10 min sus. = 207km/hr 10 min sus. = 290
km/hr max gusts.
If this is the case, then this 'midget cyclone' sure packs a punch!!!!
Note: the conversion figures were given to me, I don't know the original
source, if these are incorrect conversion figures, does anyone know more
accurate ones?
Regards,
Carl.

Special Advisory Number FOUR for Vanuatu on TC IRIS issued from RSMC
NADI
Jan 08/1440 UTC 2000 UTC.
Tropical Cyclone IRIS 05F [975 hPa] was located near 16.7S 167.5E at
081200 UTC or about 90 miles northwest of Vila on Efate Island and
about 30 miles to the west of Epi island. Position Fair based on GMS
HIGH RES EIR imagery. Cyclone is currently moving east at 10 knots
but is expected to gradually turn southeast later and accelerate.
Maximum winds are estimated at 60 knots close to the centre and is
expected to increase to 70 knots within the next 12 hours. Winds
above 47 knots within 45 miles of the centre and above 33 knots
within 90 miles of the centre.
The cyclone is a very compact midget system with maximum winds
confined close to the centre. Though the system has currently
weakened slightly due to interaction with the islands located in its
path, it is expected to intensify further once it moves on to open
ocean waters later this morning. On its current track it is expected
to pass close to Epi around 081500UTC. Expect Storm to Hurricane
force winds about Epi, Southern parts of Malekula and near by smaller
Islands. Gales will extend over to the rest of Malekula, Ambrym and
Efate islands. The rest of Vanuatu Group can expect strong winds.
Heavy rain and squally thunderstorms associated with the cyclone is
expected over most parts of the group.
Forecast position near 16.9S 168.8E at 090000 UTC
and near 17.1S 170.0E at 091200 UTC.
The next Special Advisory for Vanuatu on this system will be issued
at 082030 UTC.

Perhaps Fiji will have to become and ASWA member to get radar so that they
can check for cyclones!
On a more serious note, weather here is indicating more showers around
coming from the SE but with a more easterly component aloft. I would say
the trough is starting to extend its influence more on our weather.
Yesterday, there was large congestus as well as an anvil from one of them
to the N.

THE SYSTEM HAS SHIFTED FURTHER NORTH. THE MID-LEVEL HIGH CURRENTLY
POSITIONED OVER THE FIJI ISLANDS IS EXPECTED TO BUILD WEST-
SOUTHWESTWARD OVER THE NEXT 12 HOURS THEN SHIFT MORE TO THE
NORTHWEST CREATING A MORE POLEWARD STEERING PATTERN WITH APPROACH OF
A MID-LATITUDE TROUGH FROM THE SOUTHWEST. TC 05P (IRIS) IS FORECAST

..ditto for the Illawarra, probably even cooler. January as we know had a
30C day, of course ruining the storm potential as it was associated with
west winds, but most other days have struggled to reach 23C.
I catch a bus to work around 7am and wore a jumper ( sweater for our US
friends ) over the past three mornings Wed - Fri.

I noticed that Glen Innes scored the top 9am - 3pm rainfall of 8mm. I was at
Gerringong watching a surf carnival and perhaps double that fell from
genuine ' super drizzle '. It started as drizzle around 12am, but became
larger drops and very thick, less than 500m visibility for total whiteout.

I've been given a similar set of figures by Jeff Callaghan at the BoM,
but I think he used 0.8 for the 10min average, but 1.4 is certainly the
same. These are of course, only a general rule of thumb - the true
speeds as you know can fluctuate somewhat. Jeff did point out to me
that there is some controversy on how say the US get their wind speeds,
as they send a recon plane into the hurricane, and measure wind speeds
above the surface in the low levels, rather than just above the
surface. They then calculate what they believe to be the surface
maximum wind speeds. The problem with this is, no one is really sure if
their method is reliable enough to be accurate! As friction at the
surface slows down the wind speeds.
This problem could have partially been solved in TC Vance, with a very
high tower having an anneometer on the top, and it could have been
compared with an anneometer near the surface. Unfortunately, it was
only new, and the little computer that ran it didn't record the data!!!

Hi Carl and everyone,
This appears to be a very interesting system that is behaving in some
usual ways. The eye-like feature that appeared at about 01072100Z
proceeded over the next 9 hours to move, well, not like you would expect
an eye to move. In fact, at a temporal resolution of 3 hours, it appears
to be rotating cyclonically about some centre, with a radius of about 100
km or so, and a period somewhat more than 12 hours. This gives the feature
a speed of about 25-30 km/h. To me, the system appeared to have multiple
centres at this time. This being the case, it would seriously call into
question the Dvorak T number of T6.5 and 127 knots. I think subsequent
estimates of 45 to 50 knots would be more reliable.
Having said that, Mark Lander has had more experience with TCs than me,
and he has actually done some research into mesovortices in TC
circulations and multiple TCs, so I would be very interested in his
thoughts on this. Can I ask you where you got the quote from Carl?
Cheers,
Jonty.

Howdy all.
Great storm here atm. Just sitting off Darwin itself - lots of lightning
& deep deep thunder. Radar shows it developing rapidly with pink
area growing. Nice juicy boling towers shooting up either side of
the main updraft.
Seems to be skewing off towards darwin itself now - so heres
hoping it comes this way.

Hi all,
Jane ONeill has been chasing W and SW of Melbourne and has captured a
landspout funnel on video! It occurred at 0440z (3.40pm local) out of a
congesting cumulus on the NW flank of a small storm cell near Anglesea. It
lasted only a few moments, she has reviewed the video and confirms what see
saw - a funnel all the way to the ground, but not out of a wall cloud -
similar to the Cleve SA landspout a few years back.
Weak thunderstorm activity has been persisting in this area for several
hours, collapsing and reforming in pretty much the same location.
I have uploaded the Melbourne local scale radar to here:
http://australiansevereweather.simplenet.com/temp/20001090510.gif
Full report from Jane later tonight or tomorrow.
cheers, Michael

At 6.30pm EDT on Sunday many parts of Northern
Australia appear to be "on fire" storm wise - check out the the
200001090631 sat pic!! Darwin, the top end, western Cape York and the Kimberley
especially seem to be in the thick of it. Storms also appear to be active
through the eastern interiors of Qld, NSW and scattered through Vic, WA and to a
lesser degree SA.
Even Canberra has some storms not too far away
(after a very long bout of SDS here!!!).
And guess what?? No radar...!!!
Aaaargh......!!!

Howdy all.
Great savage squally storm slapping us around at the moment.
Great chunky low level gust front sreamed through - heavy rain now
falling. Lightning, thunder going off. Wind is the most impressive -
very strong - palms flailing in the wind. Doors slamming shut as
wind hit.
Baro pressure dropped 2 hcpascals. As i speak feels like roof my
blow off!
Excellent - radar shows some impressive intensity on the SW flank
- which is hitting here - and more rain behind. Could be an
allnighter!!
Will report when I know more.

This is really going off here now.
Visibility is about 10 - 15 meters as lagre curtains of rain lash
across driven by very strong winds - tree branches flying
everywhere. My garbage (thos big wheely ones) just blew over.
Water is slashing against windows.
Ohh I think I have died and gone to sds heaven..... :-)
Winds possibly 50 - 60 knots maybe more at this stage

G'day mate......
Your pics 17,18 and 19 are brilliant!!! How is the stacked mammatus!!
Beautiful and I think we had the best advanced gustnado we will see for a
while. I reckon it touched down over to the south of the river in the
Bundjalung National Park and then followed the Evans River down.....there
are heaps of bird feathers floating in the river today which means our
feathered friends they got either thrown from their nests or killed from the
hail wall. By the way the arcus shot I took at the Evans River
bridge.....five old Blackbutt trees were snapped off about two-thirds up
(about 40 feet from the ground) 200 metres west of me at the time of the
shot I have since discovered.....glad decision was made to get out of
there...
cheers Halden

so when and where can we see them? and if not, why not?

Actually I have just discovered a minor plus due to the cool weather, for
the first time in the 15 years I have lived here my peaches have no fruit
fly maggots. Lovely peaches too....

I just ran and checked my rain guage as the main severe part
passes and it turns to a rain event - I have had 81.2 mm in 30
mins!!!!!
Not bad hey!

As I'm sure quite a few people are aware, there is a fairly active MJO
propagating through the maritime continent region at the moment. This has
been observed to have a strong influence on the active/break periods in
the Australian monsoon, as I think Paul in Darwin is currently finding out
first hand! It also has a very strong influence on TC activity in the
Australian region, so I would expect the tempo to increase in this area
over the next week or two. If all goes to plan that is. :-)
Cheers,
Jonty.

Sorry for being a dummy, but im sure there are others like myself here who
have no idea what an MJO is... can someone explain ?
cheers

Hi Anthony and everybody,
Whilst it is true that many of the aircraft recon obs in the US are flight
level (normally >~ 700 hPa in the eye wall), there is also a dropsonde
routine on most missions that does allow surface (or near surface) wind
speeds to be directly inferred. Obviously the majority of obs on
routine recon are flight level or remote sensed, as GPS sondes are quite
costly. However, there have been specific research missions flown by the
hurricane research division of the AOML in which more dropsondes (either
the GPS or the older Omega dropwindsonde) have been used. I believe that
the knowledge gained from these missions allow reasonable estimates of
surface wind speeds to be estimated from the flight level obs over the
ocean in the majority of cases.
Once a landmass become involved it becomes a different kettle of fish. The
experiment set up on Northwest Cape was concerned mainly with observing
the boundary layer structure of a landfalling TC in detail, and certainly
would have provided extremely useful data if all had gone well.
Cheers,
Jonty.
