| 摘要: |
| 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。这种结果是与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ElNino和LaNina的发生年份存在较好的对应关系。热带西太平洋和印度洋表层水温的变化与南极海冰面积的变化存在密切关系，特别是与东南极和罗斯（Ross）海区的海冰面积的变化关系更为密切，其显著的相关关系发生在热带西太平洋、印度洋表层水温滞后海冰面积变化的16个月左右。 |

| Abstract: |
| 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 vibration period difference of the two regions. A better corresponding relation exists between the SST of the tropical Indian Ocean and El Nino and La 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. |
