Abstract：According to the data from ECMWF and CFSV2,we analyzed the response of sea surface temperature to typhoon.Three typical typhoons affecting South China Sea were selected.The results showed that SST decreased during typhoon,and the cooling range on Typhoon path was asymmetrically distributed.The maximum cooling center appeared on the right path.For instance,during typhoon Rammasun,the maximum anomaly of SST was on the right side if the cooling center was-2.5762℃,and on the left side if the cooling center was-1.441℃.Meanwhile,the correlation between SST anomaly and significant wave height,heat flux and wind speed was also studied.Statistics showed that the correlation between SST anomaly and significant wave height was high during typhoon,and the correlation coefficient ranged from 0.6 to 0.7.The minimum correlation was found to be with heat flux,and the correlation coefficient varied between 0.2 and-0.4.The higher the correlation coefficient was,the stronger the typhoon was.
