The System of Snowstorm Forecast with Analogue Method in Henan Province;

through summarizes the experience, find out some factors that influence rainstorm forecast firstly; and then making use of the complementary superiority of ANNA and RS each other, taking RS for former disposal data, constructed rainstorm forecast simu- lation model basing on RS and ANN, and put it up to the example validation.

This paper analyzed each kind of parameter of vertical energy outline chart of single station of 4 rainstorm examples from 2001 to 2003,found that using energy method as accessorial tools of conventional synoptic method had good application value in rainstorm forecast.

The rainstorm forecast system during the flood period in the region of Yellow River Delta was developed based on the classification of synoptical meteorology by combining the numerical forecast products in Japan and the actual data from 1990 to 1995.
