摘要
本文以游程理论和Markov链模型探讨北半球中纬度500hPa超长波(2,3波)波谱参数的时变规律,获得各个分波波幅增衰及位相进退的持续性和转折性的有关信息,从而为中长期天气预报提供一种统计气候学背景。
The temporal variation features of spectrum parameters ofthe 500hPa ultra-long waves in the Northern Hemisphere are inves-tigated based on the run theory and Markov model. Information of thepersistence and translation of amplitude increase/decrease and phaseadvance/retreat is obtained, thus providing a statistical climatological background for long-range weather forecasting.
