热带西太平洋、印度洋表层水温的变异特性及其对南极冰面积变化的响应

应用海洋表层水温资料（ＣＯＡＤＳ资料），分析研究了对全球气候有重要影响的热带西太平洋、印度洋海洋表层水温的年变化和年际变化的特性，探讨了与ＥＮＳＯ和南极冰面积变化之间的联系。结果表明，热带西太平洋及印度洋表层水温具有明显的年变化和年际变化而且它们之间存在不同的变化趋势。这种结果是两大洋的水温振荡周期不同有较大关系。热带印度洋表层水温的年际变化与Ｅ１ Ｎｉ￣／ｎｏ和Ｌａ Ｎｉ￣／ｎａ的发生年份存在较

THE CHARACTERISTICS OF THE SST IN THE WESTERN PACIFIC AND INDIAN OCEAN AND ITS RESPONSE TO THE ANTARCTIC SEA ICE AREA CHANGE

In this paper, the monthly and annual characteristics of the SST of the tropical western Pacific and indian Ocean, which have an important influence on the climate change of whole world, are analyzed using COADS, together with their relation to ENSO and the Antarctic sea ice. The result shows that the monthly and annual variations in the SST of the tropical western Pacific and Indian Ocean are significant and are different betWeen the tWo regions. The result is closely related to the vibrations period difference of the two regions. A better corresponding relation exists between the SST of the tropical Indian Ocean and EI Mino and in Nina. The SST of the tropical western Pacific and Indian Ocean and Antarctic sea ice area has a close relation, and the Ross Sea area in particular. The outstanding correlation is that there is a 16 month SST lag for the Antarctic sea ice area.
