Abstract

Abstract:

Based on the observed sea-surface temperature (SST) data from 10 ocean observation stations in the coastal region off South China (CRSC) from 1960 to 2009, the authors analyzed the variation characteristics of the high-SST events over the 50 year record. The results show that the high-SST events mostly happened during June to August, and most often in the northeast of the Beibu Gulf and least in the coastal waters off eastern Guangdong Province; the regional difference of high-SST events was caused by regional differences of upwelling and tropic cyclone, with yearly-averaged SST showing a rising trend under global warming. The past 50 years can be divided into two periods of relatively warm and cold. The yearly frequency and the number of days in all of the high-SST events in the relatively warm period and the lasting time of every high-SST event both showed rising trends compared with the relatively cold period.

Key words: coastal waters off South China, sea-surface temperature (SST), high-SST event, variation characteristics
