Abstract

The relationship between the upper ocean thermal structure and the genesis locations of tropical cyclones (TCs) in the South China Sea (SCS) is investigated by using the Joint Typhoon Warning Center (JTWC) best-track archives and high resolution (1/4 degree) temperature analyses of the world’s oceans in this paper. In the monthly mean genesis positions of TCs from 1945 to 2005 in the SCS, the mean sea surface temperature (SST) was 28.8°C and the mean depth of 26°C water was 53.1 m. From the monthly distribution maps of genesis positions of TCs, SST and the depth of 26°C water in the SCS, we discovered that there existed regions with SST exceeding 26°C and 26°C water depth exceeding 50 m where no tropical cyclones formed from 1945 to 2005 in the SCS, which suggests that there were other factors unfavorable for TC formation in these regions.
