摘要：Typhoon is composing of strong winds causing upwelling/mixing of sea water, which reduces Sea Surface Temperature (SST). SST cooling depends on intensity and translation speed of typhoon. In this paper, typhoon Haikui induced SST cooling variations were analyzed with satellite-derived data. Typhoon produces SST cooling in both sides of the track, right side cooling is due to upwelling/mixing (depends on the intensity of the typhoon) and rainfall induces SST cooling in the left side. Typhoon Haikui induced SST cooling over the coastal region is found about 1.9°C due to lower translation speed leading to upwelling, also due to rainfall. The spatial extent of the cooler SST increased after typhoon landfall, especially over coastal regions. SST cooling over study area is having an inverse relation with typhoon translation speed as well as rainfall. Due to heavy rainfall and air-sea interaction process, SST cooling is higher at coastal waters and cool waters persisted for few days after typhoon landfall.
