摘要： 利用1951～2000年营口夏季降水量和前期500hPa高度场、北太平洋海温资料,分析了夏季异常旱涝年的前期秋季(9～11月)、冬季(12月—翌年2月)500hPa高度场和北太平洋海温场及环流场特征。结果表明:前期秋、冬季海气资料与夏季降水相关较好,且存在“隔季相关”的现象。

Abstract: Based on the summer precipitation in Yingkou from 1951 to 2000 and preliminary 500hPa contour field as well as ocean temperature in North Pacific Ocean,the characteristics of 500hPa contour fields of preliminary autumn season(from September to November),winter season (from December to February)and ocean temperature field as well as circulation field in anomalous summer years were analyzed.The results indicated that the ocean temperatures in preliminary autumn season and winter season had close relationships with summer precipitations.
