热带西太平洋海－气热量通量研究──Ⅲ．冬季天气过程海－气热量交换的特征

A STUDY ON ATMOSPHERE-OCEAN HEAT FLUX OVER TROPICAL WESTERN PACIFIC ──Ⅲ. ATMOSPHERE-OCEAN HEAT EXCHANGE UNDER WINTER WEATHER CONDITION

根据执行ＴＯＧＡ／ＣＯＡＲＥ研究计划在热带西太平洋进行考察的结果，对调查海区海－气界面热量交换进行了分析。结果表明：冬季在热带扰动的影响下，调查海区海－气热量交换非常强烈，在风速较小、天气情况良好的情况下，调查海区海水得到的热量远大于失去的热量，调查海区海水对大气加热的变化与表层海水温度的变化并不一致，热带太平洋信风的加强对暖池的建立似乎是至关重要的。

Based on data collected during TOGA COARE Cruise No. 1, an analysis is made on the atmosphere-ocean heat exchange over the Tropical Western Pacific. The results show that exchange was very strong over the area within tropical disturbance in winter,under condition of weak wind speed and very good weather the ocean received more heat than it lost. The variation of the area over which the atmosphere is heated by the ocean does not coincide with that of sea surface temperature. It seems that the intensifying of the tropical trade wind is a crucial factor for establishment of the Tropical Western Pacific warm pool.
