摘　　要：应用单多普勒天气雷达观测资料、天气实况和卫星云图对１９９５年６月２２日出现在北京地区的冰雹天气过程进行了分析．从单多普勒雷达资料反演出的水平流场和垂直气流结构可以看出这次过程沿着辐合带发生，垂直剖面上的气流有良好的组织，表现出强烈的旋转和上升．这种气流结构不同于传统的超级单体雹暴中的气流模式，有其局地地形特点．By using the singleDoppler weather radar observations, synoptic situations and satellite cloud pictures, the hailstorm occurring on June 22, 1995 in Beijing area is analyzed. From the retrieved horizontal and vertical wind fields, it is shown that this process occurring along a convergence band and the air flow in the vertical sections are wellorganized with upward and strong rotations. The wind structure, different from traditional supercell storm conception, has its local topographic characteristics. 
