摘　　要：利用国家气候中心月动力延伸模式地面气压场格点输出资料,通过普查计算春季历史上的地面气压场,确定了影响兴安盟春季降水的地面环流分型,并利用地面环流分型作兴安盟春季降水量预测,效果较好。Using the surface pressure field grid data that come from monthly dynamic extended mode of national climate center, and seeking surface circulation model of spring precipitation weather in Xing＇an city,. Surface circulation model which influenced Xing＇an city spring precipitation was confirmed in Xing＇an city by investigating and calculating the surface pressure field in history, and spring precipitation was forecasted base on it. The practice shows that the effect was very well to forecast precipitation.

关 键 词：地面环流分型 短期气候预测 降水量 月动力延伸模式
