长期天气过程的隔季相关

CORRELATIONS AT 5-7 MONTH INTERVALS IN LONG-RANGE WEATHER PROCESSES

本文比较全面地讨论了大气中相隔5—7个月的相关现象——隔季相关,指出隔季相关是长期天气过程的一个重要现象,它具有明显的纬度效应和季节变化。进而讨论了这种现象与北太平洋海温的关系。

Tn this paper, correlations at intervals of 5-7 months are discussed in detail.Long range forecasting practice reveals an important phenomenon of correlations between predictands and predictors 5-7 months apart. In analyses of 500 hPa circulations, the correlation is the most significant in mid-and-high latitudes between winter and summer. Asia,the Pacific and Atlantic Oceans are the 3 key regions for this correlation in Northern Hemisphere. It is also found in ocean, possibly caused by air-sea interactions, partly.
