摘　　要：在汛期的短时预报工作中,常规资料从时间分辨率和空间分辨率都不能满足短时预报,尤其是灾害性天气的临近预警的需求。TBB资料以其高时空分辨率能够很好地反映强天气系统的发生、发展和消亡,尤其能定量指示对流云的发展高度,通过分析TBB资料,找出了可以进行强对流天气临近预警的关键区和关键指标,尤其当亮温在-63℃～-80℃时对暴雨的产生有很好的指示作用,强对流的面积和层次的变化对暴雨也有很好的指示作用,不但可以大大降低灾害性天气的漏报率,也在短时预报的精细化和准确率上有明显提高。同时,还提供了TBB资料处理和实时显示系统,处理部分包括用MATLAB编程将9210下传的每小时1次的TBB资料转换成图像文件,实时显示系统具有动画、统计和单点显示等功能。The data of TBB has high temporal-special resolution. And it can describe how the heavy convective cloud generates, develops and dissipates, especially TBB can be used to determine the top height of convective cloud. Based on the hourly data of TBB obtained from CMA, the key areas for severe convective weather warning and the key indicator for nowcasting of heavy convective system are found. In addition, the displaying system of TBB, which consists of the functions such as animation, statistics and point displaying, is set up.
