| 摘 要： | 文章应用多普勒雷达资料，并结合天气图、卫星云图等资料对2001年12月12日黑龙江省西南部地区一次大范围的较大降雪过程进行了分析。通过对这次较大降雪过程的多普勒雷达探测，分析了这次降雪回波过程的特征，分析了回波强度的不均匀性、速度场回波的低空急流和高度显示的二层云结构等特征，对大雪探测和预报都具有一定的意义。

| Abstract: | Based on the satellite images and synoptic charts and the radar(CINRAAD/CC) data of a heavy snow in southwestern of Hei Longjiang Province on December 12, 2001 ,the snowing weather process is analyzed. The result shows that the characteristics, such as the inhomogeneity of reflectivity, low level jet in speed field and two layer structure in height field can be obtained with the new generation weather radar ,as well as the difference of radar echoes of snow and rain is compared. |
