Aiming at the two heavy rainfalls over Jianghuai area on 14 July, 2007 , and 16 August, 2008, the cloud liquid water path retrieved from the visible, i nfrared and nearinfrared data of FY-2C satellite is compared with the precipi ta tion data of the same period. The results show that when the cloud liquid water path maintains large value, strong precipitation occurs on the surface. There ex ists a positive relationship between the precipitation and the cloud liquid wate r path. It indicates that the cloud characteristic parameters product is usab le in the precipitation analysis.
