Inter-annual variation of Sea Surface Temperature in the Bohai Sea

Sea Surface Temperature (SST) is an auxiliary parameter of quantitative detection of the sea environment, which has showed comprehensive results of the sea thermal, dynamic process and the air-sea interaction, such as the research of oceanography issue, which includes ocean circulation, water mass, ocean temperature and salt peak, upwelling and sea water mixture. In this paper the SST in the Bohai Sea has been analyzed based on the remote sensing data from 2003 to 2009, which shows in the same seasons there are significant changes 3 years period in winter and spring, and change little in summer and fall. But in the same months there are 2-3.5 years period. From the SST spatial distribution in the Bohai Sea has a significant seasonal difference, overall, the temperature distribution in the Bohai Sea change from low to high according to the situation from north to south.
