数值化动态云图是一种在保留常规云图的基本信息的基础上，增加同窗定量化显示中尺度对流系统（ＭＣＳ）静态与动态特征功能的新型云图，它比通常的ＧＭＳ－ＩＲ云图具有更多的信息荷载，更丰富的信息内含与更好的实用性．文中提出了以双时次ＧＭＳ／ＩＲ通道数据合成数值化动态云图的技术原理和技术模式．
The numerical dynamic cloud image is a new type of cloud image that adds the basic information of the conventional cloud image and adds the function of classifying the static and dynamic characteristics of the mesoscale convective system (MCS) quantitatively. It has more than the usual GMS-IR cloud image The information load, richer information content and better usability. In this paper, the technical principle and technical mode of synthesizing numerical dynamic cloud image with double time GMS / IR channel data are presented.
