Abstract

The multi-factor integrated correlation probability method and the multi-parameter dot pitch line method are used to analyze 160 hailstorm cases occurred in the plain region of Ningxia in flood season from 2003 to 2008. The quantitative comprehensive forecast index of severe convection weather in the plain region of Ningxia discriminated by Doppler Radar was found. The result shows that the success rate of identification of hail,heavy rain and other severe convective weather could reach to 87.1% while the comprehensive forecast index reaches 2.8.
