Through many field campaigns (including GIMEX) from 1999 to 2002, the Taiwan Aerosonde Team (called TAT) ,organized by the National Taiwan University, Central Weather Bureau (CWB) and Chung-Shang Institute of Scientific Technology (CSIST), has accumulate mature experience on Aerosonde operation and data analysis. The sixth Typhoon observation mission on Oct.16,2001, Aerosonde entered Typhoon Haiyan circulation and got more exciting in-situ meteorological data. The preliminary comparison between Radar derived parameters and Aerosonde in-situ observations has been presented in academic conferences. In the past one year, TAT worked a 7-day field experiment called 「Bashi Channel Weather Experiment (BCWEX)」. We navigated Aerosonde with the real-time Radar image at Ken-Ding weather station. The launch and recovery site is 30 km away from the radar station, then Aerosonde was remote controlled to approach the precipitation systems. We also tested the 400-km remote navigation of Aerosonde through telephone modem by Central Weather Bureau at Taipei. During BCMEX, Typhoon Rammasun approached north-eastern Taiwan, TAT moved soon to I-Lan base and launched Aerosonde there. No available reconnaissance flight in this case, because Typhoon Rammasun didn’t close the coast at all. Typhoon reconnaissance observation will be operated continuously by TAT in this year. Cooperating with GPS-dropsonde surveillance operation for W48~W60 Typhoon warning, Aerosonde takes the near-coast reconnaissance observation during W12~W24 time window. The NOAA/FSL Local Analysis and Prediction System will be used to provide hourly marine wind field for turning the flight route of Aerosonde. After the field task, LAPS will be used again to diagnose Aerosonde flight-level data.颱風觀測無人飛機探空投落送探空typhoon observationAerosondedropsonde
