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.

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. NOTE: In the case of the third system included below, the LOW was classified as a tropical depression only by the Meteorological Department of Thailand. Huang Chunliang sent me their track for this depression--a special thanks to Chunliang for sending the information.

In the case of Tropical Cyclone Upia, the track presented above was taken from JTWC's warnings except for the last three positions. The reasons for excepting my normal procedure were: (1) Port Moresby had computer problems which prevented their earlier warnings from being received, (2) Brisbane apparently placed some of their own analyses of Upia on BoM's website for certain synoptic hours due to the unavailability of Port Moresby's warnings, and (3) even with Brisbane helping out, I still missed some of the warnings, which explains the gaps in the Central Pressure and 10-min avg MSW columns. However, the center position coordinates in general agreed quite well with those from JTWC with only three annotations needed in the Remarks column. ************************************************************************* ************************************************************************* !!!!!! IMPORTANT NOTE - PLEASE READ !!!!!! It has been brought to my attention that I should repeat in the cyclone tracks file the caveat which is included in the Author's Note at the end of the cyclone summaries. The tropical cyclone tracks which I prepare are based upon the operational warnings/ advisories/advices/bulletins from 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: In the near future I shall contact the other tropical warning centers to see if I can locate any links to sites where their "best tracks" might be archived. ************************************************************************* ************************************************************************* ************************************************************************* Revised 08.01.02 / Typhoon2000.ph, Typhoon2000.com
