The analysis of precipitation and cloud form in spring and autumn in Henan Province shows that the rainfall in these two seasons is mostly generated from s tratiform cloud and wave cloud. So the method of precipitation classification fo recast for subregions in Henan Province can be used to ascertain the time and region that are fit for artificial precipitation enhancement by aircraft. By usi ng the products from NWP model T213 and successive regression, predictive equati ons for precipitation classification forecast in different subregions are set up. In addition, a postprocessing method is used to improve the forecast of th e subregion which is of low accuracy. The results show that this method can be a guidance for artificial precipitation enhancement.
