中文摘要: 利用我国华南3省24个站1951～1995年2～4月的月平均气温资料分析该地区春季低温的气候特征,发现有6个严重低温年:1957、1968、1969、1984、1985和1988年。1968年最为严重。严重低温主要发生在3月和4月。福建的低温较频繁,广西的低温较严重。华南春季低温年际变化有明显的阶段性,80年代低温频繁,90年代低温最少,其它年代低温频数大体相当。春季低温和高温年份,亚洲中高纬度大气环流、西太平洋副热带高压以及太平洋热带海洋状况都有显著的差异。华南春季低温与亚洲极涡、纬向环流指数、西太平洋

Abstract:Based on the data of monthly mean temperature of Feb. to Apr. from 1951 to 1995 in three provinces of South China, the characteristic of low temperature during spring in South China is studied. Six serious low temperature years include 1957, 1968, 1969, 1984, 1985 and 1988. The low temperature in 1968 is the most serious. Serious low temperature is mainly in March and April. Low temperature is more frequent in Fujian and more serious in Guangxi. There is an obvious phase in interannual change of low temperature. The 80′s low temperature is more frequent, the 90′s is least, and others are normal. In years of serious spring low and high temperature years, there is remarkable difference between the mid high latitudes′ circulation of Asia, the subtropical high of western Pacific, and the SST of tropic Pacific. The close relation is obvious between Spring's low temperature of South China and Asia′s polar vortex, North edge of subtropical high in western Pacific, and the SST of warm pool in the Pacific.
