The position of the circulation center relative to a deep convective cloud cluster is associated with the upper tropospheric environmental flow.
这种环流中心与云团的相对位置关系和对流层上部的环境流场密切相关。
Study shows that the process is caused by cold vortex in the east of Mongolia and subtropical high, and mesoscale convective cloud cluster is the direct reason of the local severe heavy rainfall.
发现本次过程是由蒙古东部的低涡与副热带高压共同作用发生的，而局地大暴雨的直接原因是中尺度对流云团所造成的。
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。
