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.

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。

In addition, a thought of how to use the mesoscale convergence center, TBB of convective cloud and the radar echo for rainfall rate to predict the mesoscale rain cluster is presented.

提出利用逐时的中尺度辐合中心、卫星红外云图云顶亮温及雷达回波降水率做中尺度雨团量级预测思路。

This mesoscale cloud cluster merges with the cloud cluster of a weakening TD in the end and the convective systems move into Shanghai area.

这个中尺度对流云团与减弱的TD云团最终合并，对流系统移至上海地区。
