GARY PADGETT'S GLOBAL TROPICAL CYCLONE TRACKS - DECEMBER 2003 !!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!! ************************************************************************* ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico Sources of Information ---------------------- The track coordinates, central pressure and 1-minute average maximum sustained wind values were obtained from the operational forecast/advisories issued by the Tropical Prediction Center/National Hurricane Center located in Miami, Florida. A 1-minute averaging period is the standard used by all U. S. civilian and military warning services for tropical cyclone warnings. A special thanks to David Roth of the Hydrometeorological Prediction Center (HPC) for compiling and sending me the track for the early, non-tropical stage of Tropical Storm Peter.

The CP and MSW values for that portion of the track were gleaned from ship reports. The TPC/NHC Best Track for Peter indicates that the system had achieved subtropical storm status at 07/1800 UTC and had become a tropical storm at 09/0600 UTC. The first operational advisory naming Peter was issued at 09/1500 UTC. Along with Tropical Storm Odette a few days earlier, the development of Peter makes December of 2003 the first time since 1887 that two tropical storms have formed in the month of December. Also, these two cyclones along with Tropical Storm Ana in April makes 2003 the first year since 1887 that three tropical storms have formed outside the nominal June to November season. ************************************************************************* ************************************************************************* NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180 Sources of Information ---------------------- The track coordinates and 1-minute average maximum sustained wind values in general were taken from operational warnings issued by the Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy, located at Pearl Harbor, Hawaii. The central pressure and 10-minute average maximum sustained wind estimates for most systems were obtained from warnings issued by the Japanese Meteorological Agency (JMA), which is the World Meteorological Organization's Regional Specialised Meteor- ological Centre for the basin. In a few instances, information from warnings issued by other Asian warning centers may have been utilized. The center position coordinates from JMA and other centers were com- pared with those from JTWC and annotations made in the Remarks column when the differences in general amounted to 40-50 nm or more. Michael V. Padua of Naga City in the Philippines, owner of the Typhoon 2000 website, sends me cyclone tracks based upon warnings issued by the Japanese Meteorological Agency and the Philippines' Atmospheric, Geophysical & Astronomical Services Administration (PAGASA). Also, Huang Chunliang of Fuzhou City, China, sends me each month tracks obtained from warnings issued by the National Meteorological Center of China (NMCC), the Central Weather Bureau of Taiwan (CWBT) and the Hong Kong Observatory (HKO). A very special thanks to Michael and Chunliang for the assistance they so reliably provide.

JMA downgraded the system to weak depression status (25 kts or less) at 26/0000 UTC. NMCC did not issue warnings on TC-27W as they normally issue warnings only for tropical storms/typhoons and did not adjudge this system to be of tropical storm intensity. HKO classified the system as a tropical depression but did not issue normal warnings as the depression remained outside that agency's AOR. Neither were any local numbered warnings issued by CWBT (Taiwan), but the agency did upgrade the disturbance to depression status at 24/0000 UTC, and then downgraded it back to a LPA at 27/1200 UTC. No specific wind estimations were given, but CWBT did not forecast the system to reach tropical storm intensity. ************************************************************************* ************************************************************************* NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea Sources of Information ---------------------- The track coordinates and 1-minute average maximum sustained wind values in general were taken from operational warnings issued by the Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy, located at Pearl Harbor, Hawaii. Occasionally some information may have been gleaned from the daily tropical weather outlooks and other bulletins issued by the Indian Meteorological Department (IMD), which is the World Meteorological Organization's Regional Specialised Meteor- ological Centre for the basin. The reported maximum sustained winds are based on a 1-minute averaging period, which is used by all U. S. civilian and military weather services for tropical cyclone warnings. For synoptic observations in the North Indian Ocean region, both 10-minute and 3-minute average winds are employed, but IMD makes no attempt to modify the Dvorak scale for estimating tropical cyclone intensity; hence, a 1-minute average MSW is implied. Thanks to Huang Chunliang for compiling, typing and sending me the tracks for TC-03B based on bulletins from the meteorological departments of India (IMD) and Thailand (TMD).

Initially, I attempted to supplement the JTWC-based track with positions and intensities gleaned from the IMD and TMD tracks in a manner similar to the way I treat the multiple tracks I normally have available for Western Pacific cyclones, but because those tracks contained data points at irregular hours and not at the standard synoptic hours, and also because JTWC's track was at only 12-hourly intervals, it quickly became very messy and subjective (on my part). So I've simply included the tracks based on IMD's and TMD's operational warnings below (with minor editing). +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ INDIA METEOROLOGICAL DEPARTMENT (IMD/New Delhi) ----------------------------------------------- -->Severe Cyclonic Storm BOB0303 Date Press MSW/Gust & Time Sta (hpa) (kt)/CI Position ====== === ===== =========== ============ 121112 D --- -- 4.5N 90.5E 121203 D --- -- 6.0N 89.0E 121212 D --- -- 7.5N 88.0E 121303 DD --- -- 9.0N 87.5E 121312 CS --- -- 9.5N 87.5E 121318 CS 998 -- 10.0N 87.0E 121400 CS 998 -- 10.0N 86.5E 121403 CS 996 -- 10.5N 85.5E 121406 CS 996 -- 10.5N 85.0E 121409 CS 996 -- 11.0N 85.0E 121412 CS --- -- 11.5N 84.0E 121418 SCS --- -- 12.0N 83.0E 121500 SCS 992 -- 12.5N 82.5E 121503 SCS 992 -- 13.5N 82.0E 121509 SCS 992 -- 14.5N 81.5E 121512 SCS 992 55/65/T3.5 15.5N 81.0E 121515 SCS 992 -- 16.0N 81.0E 121518 SCS --- -- Near Gunnavaram 121521 CS --- -- Near Gunnavaram 121603 DD --- -- Near Nidadavolu Note 1: This agency upgraded the LPA to depression status at 11/1200 UTC.

IMPORTANT NOTE - PLEASE READ !!!!!! To repeat the caveat which is included in the Author's Note at the end of the cyclone summaries--the tropical cyclone tracks I prepare are based upon the operational warnings/advisories/ advices/bulletins which are issued by the various tropical cyclone warning agencies around the world. Users of these tracks should be aware that they are preliminary and subject to revision during post-seasonal analyses of the cyclones by the forecasters and analysts at the several warning centers. For the Atlantic and Northeast Pacific basins, official tropical cyclone reports and "best tracks" can be found at the website of the Tropical Prediction Center/National Hurricane Center: The Joint Typhoon Warning Center's website contains links to their Annual Tropical Cyclone Reports which include that agency's "best tracks" for tropical cyclones in the Northwest Pacific basin, the North Indian Ocean, and the Southern Hemisphere: SPECIAL NOTE: Back issues of the global tropical cyclone summaries and monthly cyclone track files can be obtained at the following websites: PREPARED BY: Gary Padgett garyp@alaweb.com SIGNIFICANT CONTRIBUTIONS BY: Michael V.
