| 摘 要： | 北疆降雹云团按其卫星云图特征分为对流性和系统性两大类，又将对流性降雹云团按尺度大小分为雷暴云和对流云，系统性降雹云团按所处位置分为冷云核、云系云区和云系边缘。据此方法对1998-2001年4-9月期间北疆出现310个降雹云团进行归类分析。北疆降雹云团以对流性云团为主，它们尺度小、形状不规则、云顶亮温较高。主要出现在北疆西部和北疆沿天山中段。各类降雹云团在各地区的出现机率不同。

| Abstract: | The hail cloud-clusters in North Xinjiang were classified as convective and systematic cloud-clusters by their satellite cloud picture features. As well as the convective cloud-clusters were classified as thunderstorm clouds and convective clouds by their scale,the systematic cloud-clusters were put into three classes according to their positions: the cold-cloud-nuclei, the cloud-field and the edging of systematic cloud-clusters.There were 310 hail cloud-clusters in North Xinjiang from April to September during from 1998 to 2001. The majority of them were convective cloud-clusters, small scale, irregular figure and high cloud top brightness temperature,and appeared above the west and middle of Tianshan Mountain North Xinjiang. Each classification cloud had differ probability of appearance in every area. |
