摘要
我国６月份的降水趋势按大范围多雨区的分布位置可以分为三种类型；北方类、长江类和华南类。这种不同的降水分布型与亚洲地区西风环流、西太平洋副高以及印缅低槽等环流系统的变化有关。分析表明，近４０年来６月降水分布型存在着年代际的气候振动，他们可能是大气环流以及海温的短期气候变化的结果。
Distributions of large rain regions and precipitation tendency of the whole country in June can be divided into three types: North China type,Changjiang type and South China type. Such distributions of precipitation types associate with Westly circulation change and position in Asia and West Pacific Subtropical high and Indian-Burma low trough. The analysis suggests that the precipitation types in June is related to climatic oscillation of a adecade in recent forty years. It may be associated with influences of atmospheric circulation as well as short-term climatic change of SST.
