摘要
本文用严格的统计方法和较长时间序列的观测资料对北半球月平均环流相似性的演变做了比较全面细致的分析。结果表明:两个不同年份的月平均距平场在某个起始月相似后相似性随之变差,但过了约半年左右变得又相似。这就是所谓的长期天气异常演变过程中半年左右的相似韵律现象。
The amdogous evolution of monthly mean circulation over the Northern Hemisphere have been, overall and in detail, analysed by utilizing strict statistical method and observation data for long-time sequence.The results show that the analogue of the monthly mean anomalous fields between two different years gets gradually worse from a certain starting analogous month onwards, but about 6 months afterwards the analogue again occurs. This is the so-called analogous rhythms phenomenon for about six months in the evolution processes of long-term weather anomaly.
