GARY PADGETT'S GLOBAL TROPICAL CYCLONE TRACKS - JUNE 2001 !!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!! ************************************************************************* ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico NOTE: The tracking and intensity information for Atlantic Basin tropical cyclones is based upon operational advisories from the Tropical Prediction Center/National Hurricane Center, located in Miami, Florida, USA. The MSW are based on a 1-min averaging period, which is used by all U.S. civilian and military weather services for tropical cyclone warnings. In the case of Tropical Storm Allison, the majority of the track given below was obtained from the storm summaries issued by the Hydrometeorological Prediction Center (HPC) in Camp Springs, Maryland. The HPC assumes warning reponsibility for dying inland tropical cyclones until the threat of flooding from heavy rains is past. A special thanks to David Roth for sending me the track for a subtropical system in early May. This was covered in the May summary, and the track was also included as well. I am including the track for this system below so that it will be contained in one of the cyclone tracks files.

I did not do so for Allison for two reasons: (a) the initial special advisory at 05/1900 UTC and the next regular advisory at 05/2100 UTC gave different coordinates for 1800 UTC, and (b) for continuity with the positions in the storm summaries issued by HPC which form the vast majority of the track for Allison. Note #2: Track coordinates and intensities for 06/1500 UTC through 18/0300 UTC were obtained from storm summaries issued by HPC. The exact hour of analysis was often not explicitly stated, and when it was, some- times differed from the hour given in the table by an hour or two, but since the center was usually broad and ill-defined and also slow-moving, I made no attempt to adjust the positions to the exact advisory hour. Note #3: A location in the Chandeleur Islands off the Mississippi and Louisiana coasts reported a peak gust of 50 kts at 11/1200 UTC. Note #4: Eglin AFB (near Valparaiso, Florida) reported a gust of 47 kts shortly before local noon (11/1700 UTC). Note #5: Shortly after 2000 UTC a gust of 28 kts was measured at Vidalia, Georgia. The highest gust of 31 kts was recorded at an offshore buoy northeast of St. Simons Island. Note #6: Diamond Shoals Lighthouse reported a peak sustained wind of 32 kts at 17/0300 UTC. Note #7: Atlantic City, New Jersey, reported sustained winds of 25 kts with gusts to 34 kts at 17/0200 UTC. ************************************************************************* ************************************************************************* NORTHEAST PACIFIC (NEP) - North Pacific Ocean East of Longitude 180 NOTE: The tracking and intensity information for Northeast Pacific Basin tropical cyclones is based upon operational advisories from the Tropical Prediction Center/National Hurricane Center in Miami, Florida, for systems east of Longitude 140W; and from the Central Pacific Hurricane Center, Honolulu, Hawaii, for systems west of Longitude 140W.

Comparisons were made with track coordinates given in advisories from the meteorological services of Japan (JMA) and the Philippines (PAGASA). In general, whenever the center position differed by more than 40-50 nm from JTWC's, an entry was made in the Remarks column. Michael V. Padua, owner of the Typhoon 2000 webpage, sent me the PAGASA and JMA tracks for Typhoons Chebi/Emong and Durian, and for Tropical Depression Darna. Roger Edson, of the University of Guam, also sent me his version of a track for Darna. Huang Chunliang, of Fuzhou, China, sent me tracks for the two typhoons from the National Meteorological Center of China and the Hong Kong Observatory. A special thanks to these gentlemen for their assistance. The 1-min avg MSW were taken from the JTWC advisories while the 10-min avg MSW and central pressure estimates were obtained from JMA's advisories. The 10-min MSW estimates from the other centers follow the main track in a separate table.

Also, a special thanks to Karl Hoarau of Cergy-Pontoise University, near Paris, for sending me the results of a Dvorak analysis he performed on satellite imagery of the subject tropical cyclone. The 1-min avg MSW given in the primary track below were taken from Karl's analysis. JTWC's MSW estimates follow the track in a separate tabulation.

The peak intensities on 21 June are significantly higher than those estimated in the warnings from MFR and JTWC; however, both Roger Edson and Chip Guard of the University of Guam have expressed the opinion that the cyclone most likely was of hurricane intensity on that date. The 10-min mean winds above were obtained from MFR's warnings. JTWC's 1-min avg MSW operational estimates are listed below: Date Time MSW (1-min) in Kts (GMT) JTWC ----------------------------------- 01 JUN 21 1800 45 01 JUN 22 0600 35 01 JUN 22 1800 35 01 JUN 23 0600 25 ************************************************************************* ************************************************************************* !!!!!! 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 (ATCR) which include that agency's "best tracks" for tropical cyclones in the Northwest Pacific basin, the North Indian Ocean, and the Southern Hemisphere: For the actual Best Tracks files, click on the link for Best Tracks (in the menu on the left side of the screen) and follow instructions. In the ATCR for 2000, the Chapter 5 tab contains verification statistics of JTWC warnings for all the 2000 tropical cyclones in the Northwest Pacific, North Indian Ocean, and the Southern Hemisphere. There are gaps in the Best Tracks presented here for certain cyclones during periods in which no warnings were being issued. ************************************************************************* ************************************************************************* ************************************************************************* 07.25.01 / Typhoon2000.com
