The Greater Miami Chapter of the AMS presents
"Typhoon Cyclone Structure - 2008:
Plans for a multi-aircraft experiment in WPAC"

Dr. Pete Black
Naval Research Laboratory
Monterey, California
Distinguished Visiting Scientist
AOML, Miami, FL

May 06, 2008 at 3 PM.
Refreshments at 2:45 PM
1st floor Conference Room
Atlantic Oceanographic & Meteorological Laboratory
Miami, FL

Peter Black will be visiting AOML the week following the AMS Conference in Orlando. He will take this time to brief us on a coming research venture scheduled for this summer in the western Pacific. TCS-08 is a part of T-PARC (THORPEX Pacific Asian Regional Campaign) and will involve aircraft from NRL and the US Air Force in examining the structure of developing tropical cyclones.

Fifty people present

Neal Dorst convened the meeting and solicited nominations for chapter officers with elections scheduled for June. Names and the positions they are to be nominated for should be emailed to any current chapter officer. He also requested $10 dues for 2008. He then turned the meeting over to Hurricane Research Division (HRD) director, Frank Marks.

Dr. Marks recognized the recent winners of the Banner I. Miller award: Eric Uhlhorn and Pete Black (who were present) and their co-authores, Alan Goldstein, Mark Goodberlet, James Carswell, and Jim Franklin. He also presented plaques awarded by the U.S. Army Corps of Engineers to HRD personnel for contributions on an intergovernmental study of Hurricane Katrina.

Dr. Marks then introduced the day's speaker, Dr. Peter Black. A former HRD employee, Dr. Black is now a contract scientist with the Naval Research Laboratory and a distinguished visiting scientist with the Atlantic Oceanographic and Meteorological Laboratory. He spoke about plans for the Tropical Cyclone Structure (TCS-08) experiments scheduled for the summer of 2008. Part of the THORPEX - Pacific/Asia Regional Campaign, TCS-08 will use the resources of many Pacific-rim nations to investigate the evolution of typhoons in the western Pacific. Although the experiment will use drifting buoys, ships, land stations, satellites, and driftsondes to gather information, Dr. Black's talk focused on his area of expertise, use of aircraft platforms to probe the structure of developing tropical cyclones.

Using an idealized storm forming in the tropical Pacific, strengthening into a typhoon off the Marianas, recurving off Taiwan, and transitioning into an extratropical cyclone near Japan, he demonstrated how TCS-08 hoped to use its limited resources to monitor the storm. An Air Force C-130 from the 53rd Weather Reconnaissance Squadron and the NRL P-3 would be deployed to Guam from where they would monitor the cyclogenisis and strengthening stages. As it neared Taiwan, the U.S. aircraft would re-deploy to Kadena AFB on Okinawa while the Taiwanese Astra jet would monitor the synoptic environment. As the storm moves into the midlatitude region, the American aircraft would again redeploy, this time to Yokota AFB in Japan, while the DLR Falcon jet would take over the upper-air monitoring around the cyclone.

The purpose of TCS-08 is not only to document the life cycle of typhoons and examine their mesoscale structure, but also to provide 'ground truth' for satellite wind estimates that have been lacking in the region since the early 1990s, to test theoretical hypothesis about development mechanisms, and provide insights into the limits of model predictability of recurvature and extratropical transition. There was lively interaction between the audience and speaker during the talk and several pertinent questions asked during the follow-up session. The meeting adjourned at 4:10 PM.
