Study on the Variation of Feathers and Cause of Formation of the Oceanic Warm Pool

Abstract:

Based on the COADS data, the feathers of the seasonal variation and interannual change of the Oceanic Warm Pool are studied. The results show that the seasonal variation of the area and the center of the Warm Pool is connected with the seasonal variation of the solar radiation, while the highest value of the interannual change of area take place in the year of El Nino. The study of the seasonal variation of SST shows that the smaller the sea area and the nearer to warm pool center are chosen, the smaller the seasonal variation is presented, and there is a good positive correlation between interannual change of SST and that of area. The solar radiation and wind field are the key factors for the cause of formation of the Oceanic Warm Pool.

Key words:

oceanic warm pool; seasonal variation; interannual change; cause of formation
