摘　　要：利用红外和可见光云图亮温资料估算单站降水量级，结果发现红外和可见光云图结合估算降水量效果比单用红外云图效果要好，大雨的空报率明显降低。sing the brightness temperature data of infrared and visible cloud picture,the estimate of the magnitude order of rainfall at the single site reveals that the effect of comprehensive utilization of infrared and visible cloud picture for the estimate of rainfall is better than that with utilization of only the infrared cloud picture, and the rate of forecast in void of heavy precipitation decreases clearly.
