Characteristics and synoptics classification of rainstorm in Heilongjinang Province

通过普查 1961-2004年计 44年的历史气象资料, 对黑龙江省暴雨的降水特点及天气分类作了综述, 并对其预报问题进行了全面的探讨。指出黑龙江省的暴雨具有明显的时空分布特征, 大地形的背风坡对暴雨分布具有重要影响; 在适当的环流配置下, 东北冷涡和东北低压是产生暴雨的最主要的高、低空天气系统。

By general surveying the historical meteorologic data from 1961 to 2004, this paper analyzed synthetically the characteristics and synoptics classification of the rainstorm in Heilongjiang Province. The results show the spatio-temporal distribution of the rainstorm in Heilongjiang Province has specific characters. Great topography has great effect on the distribution of rainstorm. Under the proper circulating condition the Northeast cold eddy and low are the supreme weather system of high and low altitude.
