摘要
普查1998～2001年4～9月的资料,得到全疆438个降雹云团。2000年降雹云团出现最多,4年内出现在5月的最多。按尺度大小将降雹云团分为雷暴云、对流云、中尺度对流系统、冷云核、系统云系云区及云团边缘6类。强对流云团是冰雹云的主体。新疆降雹云团尺度小、形状不规则、云顶温度较高。
hail clouds were found from April to September during 1998 to 2001 in Xinjiang. There were most hail clouds in 2000, most in May in four years. Hail clouds were classified 6 kinds according to scale: thunderstorm cloud, convective cloud, mesoscale convective system, cold-cloud-nuclei, cloud field of system clouds, and edge of cloud cluster. The major hail cloud was strong convective cloud. In Xinjiang, hail clouds were small scale, irregular figure, high TBB.
