印度洋海温信息区和海面热交换的特征分析
AN ANALYSIS OF THE CHARACTERISTICS OF SST SIGNAL AREAS AND SURFACE HEAT EXCHANGE FOR THE INDIAN OCEAN
-
摘要: 本文分别研究了印度洋海温信息区和海-气能量输送的年、季分布特征,讨论了印度洋热带地区海-气相互作用的一般形态。得出,印度洋海温可划出三个信息区,在20°s附近和阿拉伯海10°N附近各有—个东西向的最大海-气能量输送区。它们都有明显的季节变化,印度洋重要海区是阿拉伯海和东赤道印度洋,因为该两个海区不仅能表征印度洋海洋热状况的基本性质,而且是印度洋海-气相互作用过程的关键海区。Abstract: In this paper, annual and seasonal features of the distribution of SST signal areas and air-sea energy transport are studied and general ways discussed in which air-sea interaction takes place in the tropical Indian Ocean. Three SST signal areas are identified and separate maximum zonal areas for the transport of energy between the air and sea are located near 20°S and 10°N (in the Arabian Sea), showing significant seasonal variations. In the area of the Indian Ocean, the Arabian Sea and eastern equatorial Indian Ocean are two key areas, for they not only depict the basic characteristics of the conditions of maritime heat of the ocean, but act as key regions where the air-sea interaction takes place.
