海洋对大气环流大尺度变化的影响,是研究气候异常的重要基础,而海洋信息区是海气相互作用的关键区,它的温度变化在很大程度上可以反映海洋热状况的大尺度变化。本文,根据1950～1979年热带太平洋(42°N～42°S,130°E～80°W)的表层水温资料(COADS),采用两次相关计算标准信息量指标的方法确定了信息区;讨论了各信息区的水温与全区水温同期相关的特征,对研究气候异常提供了海洋热力基础。
The impact of oceans on the large-scale atmospheric circulation is an important basis for studying the anomalous climate. Oceanographic information area is the key area for the interaction of the sea-air. Its temperature variation can largely reflect the large-scale changes of ocean thermal conditions. Based on COADS from 42 ° N to 42 ° S and 130 ° E to 80 ° W from 1950 to 1979, the information area was determined by two correlative calculation of standard information index. Discussed the characteristics of the water temperature in all the information areas and the water temperature in the whole area over the same period, and provided the ocean heat foundation for studying the climate anomalies.
