摘要
通过对两个冬季个例的诊断分析,讨论了赤道东太平洋海表具有不同温度时,沃克环流与哈得来环流的三维结构以及它们在角动量和热量输送中的作用。阐述了赤道东太平洋海温异常对东亚西风强度影响的物理过程。
According to the abnormal sea surface temperature of the east equatorial Pacific Ocean,two winter months(a cold and a warm)are selected.The differences of the structure of Hadley and Walker circulation in the pairs of opposite cases and their influences on the poleward transport of angular momentum and the vertical transport of heat in the atmosphere are given.So that the physical mechanism of the effect of the abnormal sea surface temperature of the east equatorial Pacific Ocean on the westerlies over East Asia is revealed.
