GLOBAL TROPICAL CYCLONE TRACKS - JUNE 2011 !!!! IMPORTANT -- PLEASE SEE INFORMATION AT END OF FILE !!!! +++++ IMPORTANT NOTE BY AUTHOR -- PLEASE READ +++++ Effective this month, I am making a change in the manner in which I report the coordinates and MSW/CP for the Atlantic and Northeast Pacific basin tropical cyclones. NHC (and CPHC) issue advisories at three hours past the standard synoptic hours of 0000, 0600, 1200, and 1800 UTC. (In the following discussion, I refer to the advisory times as SynHr+3.) Whenever any coastline is under a tropical storm watch (or higher) intermediate bulletins are issued at the synoptic hours. The regular advisories issued at SynHr+3 contain a line giving the position coordinates for the previous synoptic hour. My procedure has always been to time stamp each line with synoptic hour and report the coordinates for that hour, but taken from the regular advisory issued at SynHr+3. However, there is no MSW estimate included for the previous synoptic hour; the MSW is always the best estimate available at SynHr+3. Hence, in the case of TCs with rapidly changing intensities, this can result in a discrepancy which could be significant in some cases. Whenever intermediate bulletins were being issued, I would glean the coordinates from the regular advisory at SynHr+3 (which might not match exactly the values reported in the intermediate advisory three hours earlier), but would take the MSW directly from the intermediate advisory issued at the synoptic hour. Whenever a hurricane is approaching the U. S. coastine and moves into radar range, NHC's procedure is to issue two intermediate advisories at SynHr-1 and SynHr+1 hours. In these situations, I would still use the coordinates for the synoptic hour taken from the SynHr+3 advisory, but average the MSW and CP from the two intermediate advisories and report those averages for the particular synoptic hour under consideration. My procedure now is going to be to time stamp the entries in the tabular tracks with the actual advisory time (SynHr+3) and report both coordinates and intensity parameters at the stated time. Whenever an initial (or otherwise) special advisory upgrading or downgrading a system is issued at an intermediate hour, I will include an extra entry to document that event. This will give the advantage of having the position estimate and MSW/CP estimates relate to the same time, plus will save me much time in that I won't have to store and then later click open all the intermediate bulletins--only those few I need to save for documenting an upgrade or downgrade or some other noteworthy event. ************************************************************************* 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.

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.

Kevin Boyle, of Stoke-on-Trent, UK, will be preparing the tracks for Northwest Pacific basin tropical cyclones during the most active part of the NWP season from June through December. Michael Bath, of McLeans Ridges, New South Wales, Australia, is now preparing the track files for Australian Region and South Pacific tropical cyclones. Also, Steve Young sends me tracks with data for the pre-warning and post-warning stages of tropical cyclones in all basins, prepared primarily from NCEP re-analysis data or else taken from NRL files. A very special thanks is due to Kevin, Michael and Steve for their assistance. ************************************************************************* SOURCES OF TROPICAL CYCLONE INFORMATION The purpose of this section is to list some websites where many and varied types of tropical cyclone information are archived. Many readers will know about these already, but for the benefit of those who don't, I wanted to include them. (1) Aircraft Reconnaissance Information --------------------------------------- Various types of messages from reconnaissance aircraft may be retrieved from the following FTP site: Information regarding how to interpret the coded reconnaissance messages may be found at the following URL: Links are also included to websites with further information about the U. S. Air Force 53rd Weather Reconnaissance Squadron and the NOAA Air- craft Operations Center. (2) Archived Advisories ----------------------- All the advisory products (public advisories, forecast/advisories, strike probabilities, discussions, various graphics) issued by TPC/NHC are archived on TPC's website. For the current year (using 2004 as an example), the archived products can be found at: Links to tropical products archives for earlier years are available at the following URL: JTWC warnings for past storms are archived on the NRL Monterrey website: On the NRL site, the link to past years can be found in the upper left corner of the screen. I am not aware at the moment of any other TCWC which archives all its tropical cyclone warning/advisory products for public access, but if I learn of any, I will add them to this list. (3) Satellite Imagery --------------------- Satellite images of tropical cyclones in various sensor bands are available on the NRL Monterrey and University of Wisconsin websites, courtesy of Jeff Hawkins and Chris Velden and their associates. The links are: On the NRL site, the link to past years can be found in the upper left corner of the screen. For the CIMSS site, a link to data archives is located in the lower left portion of the screen. Additional tropical satellite imagery, along with looping ability for composite microwave imagery for the Western Hemisphere north of the equator, can be found at: (1) For the Eastern North Pacific: (2) For the Atlantic, Gulf of Mexico and Caribbean Sea: (4) Cyclone Tracking Information -------------------------------- There is a U. S. Navy site that tracks tropical cyclones at 6-hourly intervals which often includes pre and post-advisory positions. The link to the site is: Steve Young has compiled many of these tracks onto a single webpage which is very user-friendly: ************************************************************************* !!!!!! 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 Kevin Boyle michaelpace@btinternet.com Michael Bath mbath@ozemail.com.au SIGNIFICANT CONTRIBUTIONS BY: Michael V.
