摘要

本文应用计算得到的1956-1975年北半球多年月平均的对流层平均大气加热场、历年逐月距平场及波谱的振幅等资料,与我国若干地区的气候异常进行了对比分析。指出:在某地区出现气候异常的前期,北半球月平均和热场、流场或加热场的谱振幅,表现出一定的异常特征,而且相同类型异常年的特征是一致的,因而这些特征具有先兆意义。

Abstract

In this paper, we use the computed data consisting the monthly mean in many years of the average atmospheric heating field in the troposphere, the field of departure in month by month over the years, the amplitude of wave spectrum, etc, to make an analysis and a comparison with the climatic anomaly of some areas in our country.The results point out that in the earlier stage of climatic anomalyappeared at somewhere the monthly mean of the theating field,flow field or the heating field's amplitude of wave spectrum over northern hemisphere displays a definite abnormal feature, while that in unusual years of identical type is consistent.These results,therefore, have a omen significance.
