碩士 / 國立臺灣海洋大學 / 海洋環境資訊系 / 102 / The typhoon-induced sea surface temperature (SST) reduction related to typhoon intensity and translation speed is studied using remote sensing SST data from the TRMM and typhoon tracks from the Unisys website during 1998-2012. This kind of SST reduction is called cold wake. The results reveal the amplitude of cooling is well correlated with typhoon intensity and translation speed. More obvious ocean response is observed either under a more intense typhoon or under a slower-moving typhoon. SST reduction related to typhoon intensity is 4.2°C as the maximum cooling in the wake usually occurs 1 day after a typhoon passed by. SST related to translation speed even reduced by up to 5.0°C while the maximum cooling usually occurs 3 days after a typhoon passed by. In addition, the study area is divided into two individual zones, the lower latitude zone (12°~20°N) and the higher latitude zone (20°~27°N). It is found the amplitude of cooling is larger in the latter part which is assumed to be affected by the pre-existing mixed layer depth.
