摘要/Abstract

摘要： 利用燕山南麓1951-2005年夏季降水资料和NCEP再分析资料，采用统计分析等方法，对燕山南麓夏季降水演变规律进行了研究。结果表明：近55 a来，燕山南麓夏季降水线性减少趋势显著，平均每10 a年减少29 mm，夏季降水在20世纪70年代末发生了一次气候突变。燕山南麓夏季降水和东亚夏季风变化周期不一致。燕山南麓夏季降水减少主要是由于亚洲中纬度地区和极地地区环流变化造成的。

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
