摘要: 文中分析了影响中国的寒潮冷高压的活动情况,对冷高压活动的天气气候特征有了较明确的了解.冷高压次数有明显的年、月、季变化.冷高压主要出现在亚洲大陆中部,有两个中心:主中心在50~55°N,95~100°E,次中心在鄂木斯克南方.强高压分布与上述高压中心位置一致;弱高压在中国东部和沿海以及欧洲地区.迅速增强的高压分布与强高压相似,迅速减弱的高压位于中国中部.高压移动路径以自西向东为主,北方有4条路径补充,寒潮爆发时向东偏南和东南方各有一条移动路径.Abstract: This study was performed to investigate the climatic characteristics of the cold wave high with the .The number of cold high was changed with year and season.The majority of cold high was distributed in the continent of Asia and with two centres,The main centre was located at 50-55°N,95-100°E,the locat ion of the strong cold high and the fast strengthen cold high was same as the main cold high distribution centre.The weak cold high was located at the East China and the European.The fast weaken cold high was located at centre of China.The major path of cold high was east ward,and there are four supplement paths southward to the major path from high latitude.
