摘　　要：文章针对2010年12月9—10日兴安盟出现的大雪天气过程,分析了这次大雪过程在各站历史上的排位和对白灾的影响;从高空环流形势的影响系统及风场的分布特征,地面低压移动方向和位置进行分析;分析了物理量场中的相对湿度、涡度、散度、垂直速度、风场等对本次大雪的作用。最后对欧洲预报,T639、德国、日本降水格点,日本传真图等数值预报场在本次大雪预报中的效果进行检验分析。Aiming at the heavy snow weather process occurred in Hinggan League on December 9, 2010, this paper analyzed the sequencing of this heavy snow weather process in every, meteorological station in history and it＇s impact for white disaster. The influence of the relative humidity, vorticity, divergence, vertical velocity and wind field in physical quantity field for this heaW snow weather process were analyzed in the aspects of the influence system of high altitude circulation feature, the distribution characteristics of wind field and the moving direction and location of ground infrabar. Finally, the forecast effect of numerical forecasting products in Europe and T639, Germany and Japan grid precipitation, Japan fax diagrams were tested.
