GARY PADGETT'S GLOBAL TROPICAL CYCLONE TRACKS - APRIL 2004 !!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!! ************************************************************************* 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). A very special thanks to Michael for the assistance he so reliably provides.

NMCC assigned a peak 10-min avg MSW of 100 kts for Sudal, and 100 kts was the peak estimated by PAGASA during the four days the typhoon was within that agency's AOR. The CWB of Taiwan's peak 10-min avg MSW was 85 kts--the same as Japan's. HKO estimated Sudal's peak MSW at 95 kts, but that agency did not issue real-time warnings on the cyclone as it remained outside their AOR. The HKO peak was taken from the "Overview of Tropical Cyclones in April 2004" written by the agency. (A special thanks to Huang Chunliang for compiling and sending the peak MSW information from the Asian TCWCs.) ************************************************************************* ************************************************************************* NORTHEAST AUSTRALIA/CORAL SEA (AUE) - Longitude 135E to 160E Sources of Information ---------------------- The track coordinates as well as the central pressure and 10-minute average maximum sustained wind estimates were obtained from warnings issued by the Tropical Cyclone Warning Centres at Darwin, Northern Territory; Brisbane, Queensland; and Port Moresby, Papua New Guinea.

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.
