Monthly Global Tropical Cyclone Tracks December 2014 [Summaries and Track Data] [Prepared by Steve Young] |
Global Tropical System Tracks - December 2014
The following Tropical System tracks are compiled from various centers, but
unless otherwise cited, the data is from the Naval Research Laboratory (NRL)
or from a reanalysis using GRADS. NCEP Reanalysis data provided by the
NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their Web site at
http://www.esrl.noaa.gov/psd/.
The data usually does not match the information from the advisories, but is
closer to the Best Track data. However official Best Track data should
be considered the final and official tracks. The data also includes
Investigation areas as well as pre- and post-advisory information
With the September 2014 issue, I added a column, labeled "ST" to document the
Status or Strength of the system. Several times in 2014, we have had systems
with gale winds (35+ kts) but the systems were not closed and thus did not qualify
as a Tropical Cyclone. This classification is an attempt to clarify the system's
status. Codes to be used are:
W - Wave
B - Disturbance
L - Low
D - Depression
T - Tropical Storm
H - Hurricane/Typhoon
R - Remnent Low
E - Extropical
SS - Sub-tropical Storm
SD - Sub-tropical Depression
SPECIAL SUMMARY 1. COMPARING 23W (JANGMI) AND 90W (INVEST)
There has been discussion on the question of the relationship between 23W (Jangmi) and 90 W.
JTWC considered this to be separate systems however JMA analysis and discussion imply that
these are the same system. The following table lists the positions from NRL and JMA. NRL
data can be considered to be "Best Track" while the JMA data is operational data.

Note that reanalysis does not show any low pressure area near the (NRL) 90W position until 01 January 2015 1200z but
there is a significant jump of the low between 0600z and 1200z. At the time of this writing, we do not know what
the JMA or JTWC "best track" will show, but this Author feels that 23W disappated 01 January 2015 after 1200z and
the system designated as 90W represents a distinct system which JMA considered to be a Tropical Depression.
SPECIAL SUMMARY 2 02S (2010-2011) TROPICAL CYCLONE ANGGREK
Tropical cyclone ANGGREK formed in the South Indian Ocean in late October 2010. Operationally, the system was
tracked by Joint Typhoon Warning Center (JTWC) and the Australian Bureau of Meterology (BOM). The JTWC Best
Track lists the maximum 2-minute winds at 55 knots and a central pressure of 982 mb. The BOM operational
warnings listed maximum 10-minute winds of 50 knots and a central pressure of 986 mb. However the BOM
Best Track lists the maximum 10-minute winds of only 21 knots and considers the system as a tropical low
rather than a tropical cyclone. The Author has re-examined this system in an attempt to determine the
actual status of the system.
Using reanalysis data from Earth System Research Laboratory - Physicial Sciences Division *, we performed
a 6-hour sea-level pressure analysis and found a large and symmetrical cyclone with a track similar to
both the operational and best track data. This track passed approximately 70 kilometers from Cocos
Island airport (WMO number 96996) which provided the only observations near the system. Maximum
reported winds were from 01 November 2010 at 19:30 U.T. and were 24 knots. We were unable to locate
any observations of gale (35 knot) winds associated with the system.
Therefore, we examined satellite observations. Polar satellite visual pictures showed a well formed
cyclone with a feature consistent with a developing eye on 01 November 2010. Additionally, an operational
analysis by NOAA Regional and Mesoscale Meterology Branch (RAMMB) using an experimenta; Multiplatform
Satellite Surface Analysis shows an asymmetric wind field with maximum winds of 55 knots in the
west quadrant. It should also be noted that the 35 knot winds extended only approximately 50 kilometers
in the direction of Cocos Island airport.
Thus, the Author feels the Satellite presentation with a possible eye feature as well as the RAMMB wind
field analysis are consistent with this system being a Tropical Cyclone with maximum winds of 50 - 55
knots.

* A question has been asked about the first three positions in the track of 93P - 03F.
These positions are taken from Naval Research Lab information which, in the early
stages often track satellite features rather than a defined low pressure area. This
often leads to abrupt shifts in location as convection wanes, especially during the
disturbance stage. Reviewing satellite pictures, I believe that the positions are
part of a large disturbance where the western part waned as the easten part developed,
At times, NRL will assign a new invest number when this occurs, apparenly in this
case they retained the initial number. As the author of these tracks, I usually choose
NOT to question the data, but present the data for the readers to evaluate. In this
case, I leave the initial data, but suggest that it could be appropriate to ignore the
track prior to 20 December 2015 1200 UTC.
