Using the data of surface observation, cloud classification and blackbody temperature from 1 April 2012 to 31 July 2013 and according to different weather types, this paper states the background, analyzes the cases and discusses the relationship among cloud classification of satellite data, TBB products, weather phenomena and cloudy shapes. The results show that after cancelling surface cloudy observation, we can carry out the cloud observing operation based on cloud classification and correct the errors by combining TBB and weather phenomena. When TBB<240 K and variability is close to zero in the course of changing from negative to positive value, thunderstorms are always prone to occur and the cloudy shape is cumulonimbus cloud. When TBB is between 240 K and 260 K, there will be stable precipitation and cloudy shape is stratocumulus or altocumulus.
