| 摘 要： | 角动量输送是维持、产生大气环流变化的一个重要物理量。把角动量的涡动输送写成谱函数形式,便于对不同波长的波动角动量输送进行分析研究。文献1]用3个冬半年资料研究中纬度情况。为了揭露不同纬度角动量谱的中期振荡及其相互关系,本文利用14年冬季资料进行分析,并对其中若干异常梅雨年前冬的情况进行对比讨论。

| Abstract: | By using 500hPa winter daily data of height from 1971 to 1989, the spatial and temporal spectral analysis is investigated. The main medium-range oscillalions of total amount and every components of The angular momentum transport at 70°N, 500N and 30°N and their coherence feature are revealed. The same analysis is also carried out preliminarily in order to obtain the difference of above feature at preceding winters of several anomalous Meiyu years in 1971-1984. |
