摘要
本文研究了我国东部夏季降水的空间异常分布以及时间演变特征,探讨了冷空气低频振荡和东亚季风涌与多雨年淮河流域夏季降水的对应关系。研究结果表明:(1).我国东部夏季降水可分为四个地区,其空间分布及时间序列具有一定的独立性;(2)持续性降水都对应着冷空气低频振荡和东亚季风涌的正值。
Spatial distribution anomalies and temporal evolution characteristics of the summer precipitation in the eastern China are analyzed.The relationship between the low frequency oscillation of cold air and the east Asian monsoon surge and the summer precipitation in the Huaihe Valley in rainy years are discussed.The results show that:(a)the summer precipitation of the eastern China is divided into four areas,which has independent spatial distribution and temporal series;(b)the continuous precipitation corresponds to the positive of the cold air low frequency oscillation and east Asian monsoon surge.
