摘要/Abstract

摘要： 利用燕山南麓1951-2005年夏季降水資料和NCEP再分析資料，采用統(tǒng)計(jì)分析等方法，對燕山南麓夏季降水演變規(guī)律進(jìn)行了研究。結(jié)果表明：近55 a來，燕山南麓夏季降水線性減少趨勢顯著，平均每10 a年減少29 mm，夏季降水在20世紀(jì)70年代末發(fā)生了一次氣候突變。燕山南麓夏季降水和東亞夏季風(fēng)變化周期不一致。燕山南麓夏季降水減少主要是由于亞洲中緯度地區(qū)和極地地區(qū)環(huán)流變化造成的。

Abstract: Based on the summer rainfall data at the southern foot of the Yanshan Mountains and NCEP reanalysis data, by using statistical methods and contrast analysis, the evolutional tendency of summer rainfall at the southern foot was analyzed. The results show as follow: the summer rainfall has shown an obviously linear decreasing tendency of 29 mm/10 a during the past 55 years, an abrupt climate change took place in the later 1970s. And change periods of the summer rainfall differ from those of the East Asian summer monsoon.The decrease of summer rainfall at the mountain foot is mainly due to the change of atmospheric circulation patterns over mid-latitudes of Asia and the Arctic region.

Key words: southern foot of the Yanshan Mountains, summer rainfall, East Asian summer monsoon
