Northern Hemisphere 2006 Tropical Cyclone Season Review [Summaries and Track Data] [Prepared by Gary Padgett] |
A REVIEW OF THE 2006 TROPICAL CYCLONE SEASON
FOR THE NORTHERN HEMISPHERE
Following is a tabular summary of all the tropical depressions,
tropical storms, hurricanes, and typhoons which occurred in the
Northern Hemisphere between 1 January and 31 December 2006, as
reported in the Monthly Global Tropical Cyclone Summaries prepared
by the author.
(1) Number - this is the sequential cyclone number assigned by either
TPC/NHC, CPHC in Honolulu, or JTWC. If neither of these
agencies issued any warnings, no number will be given.
(2) Name - the name (if any) assigned by either TPC/NHC, CPHC, IMD,
or JMA (and PAGASA for Western North Pacific systems in
their area of warning responsibility).
(3) Dates - range of dates for which tracking information for the
cyclone is available in the Global Tropical Cyclone
Tracks files prepared by the author.
(4) Pressure - Lowest central pressure (either estimated or recorded)
during the lifetime of the cyclone. For Atlantic and
Northeastern Pacific systems these will be the values
reported in operational advisories from TPC/NHC or
CPHC. For Northwest Pacific systems the central
pressure estimates are taken from advisories issued by
the Japanese Meteorological Agency. An asterisk (*)
following the pressure indicates the reading was an
actual measured pressure normally obtained by a drop-
sonde released during an aerial reconnaissance
flight. Central pressure is given in millibars,
which is numerically equivalent to hectopascals.
(5) MSW - maximum 1-minute average sustained windspeed in knots.
For the Northwestern Pacific and North Indian Ocean
basins, these will be the highest value assigned
operationally by JTWC. For the Atlantic and Northeastern
Pacific basins, the MSW values are taken from the
official tropical cyclone reports prepared by the
TPC/NHC Hurricane Specialists and which are available
on TPC/NHC's website: .
(6) Basins - tropical cyclone basins where the cyclone tracked during
its life:
ATL - North Atlantic, Gulf of Mexico, Caribbean Sea
NEP - North Pacific east of Longitude 180
NWP - North Pacific west of Longitude 180
(including South China Sea)
NIO - Bay of Bengal and Arabian Sea
For tropical systems in the NWP basin, two additional columns of
information are given:
(1) The tropical storm serial number assigned by the Japanese
Meteorological Agency to tropical depressions which are deemed
to have reached tropical storm intensity. This does not always
agree with JTWC's assessment.
(2) An estimate of the maximum 10-minute average sustained wind.
The value given represents the highest 10-min avg MSW assigned
by any agency. If from any warning center other than JMA, a
numbered note below identifies which center's value is given.
For tropical systems in the NIO basin, an additional column lists
the alphanumeric storm identifier assigned by the India Meteorological
Department (IMD) for those systems deemed to have reached cyclonic
storm (i.e., tropical storm) status by that agency.
A number in parentheses (e.g. (1) ) following an entry refers to
a note following the entries for the given basin. A separate table
is given for each of the four Northern Hemisphere basins.

NOTES:
(1) Ioke's JMA tropical storm number after crossing into the Northwest
Pacific basin was 0612.
(2) The lowest CP of 1006 mb was assigned by JMA after system had moved
into the Northwest Pacific basin.
(3) This system's NRL invest number was '91C', and it occurred at a
rather high latitude in the Central and Eastern North Pacific.
The system definitely appeared to be at least subtropical in nature,
and very possibly was a tropical cyclone. The intensity is based
upon a track prepared by Dr. Karl Hoarau of Cergy-Pontoise
University, Paris.

NOTES:
(1) The highest 10-min avg MSW was assigned by PAGASA.
(2) PAGASA classified this system as a tropical depression on 24 June,
and later that same day upgraded it to tropical storm status.
(3) The highest 10-min avg MSW estimated by JMA was 60 kts. PAGASA was
the only warning agency (known to the author) who upgraded this
system to typhoon status.
(4) The PAGASA name for Typhoon Xangsane was Milenyo.
(5) The peak 1-min avg MSW of 155 kts was obtained from Dvorak analyses
performed by Dr. Karl Hoarau of Cergy-Pontoise University, Paris,
and is in agreement with intensity estimates from SAB and AFWA. The
highest 1-min avg MSW estimated by JTWC was 140 kts.
(6) This system appeared to be subtropical in nature. However, it was
assigned some tropical "T" Dvorak classifications by SAB who
designated it as '99W'. The peak intensity is based upon QuikScat
data.
(7) Dr. Karl Hoarau estimated the peak intensity for Chebi/Queenie at
135 kts. I have used JTWC's peak 1-min avg MSW of 125 kts, which
is good agreement with SAB's and AFWA's peak Dvorak ratings of
T6.5/6.5.

NOTES:
(1) I have learned that IMD discontinued using the former alphanumeric
designators when official naming of tropical cyclones in the NIO
basin was initiated in 2004. The IDs listed above are unofficial
and will not appear in the future in any summaries, track files, and
hemisphere reviews prepared by the author.
