Abstract:

The characteristic of Chaidamu vortices is statistically analyzed,and the evolution characteristics of Chaidamu vortices occur-
rence and development are summarized by using synoptic map and observational data in eastern Hexi region. Forecast equation is es-
tablished by using subject function, based on selection of high correlation predictor, and this forecast equation obtains better results t
forecast precipitation of low clouds in eastern Hexi region.

Key words: Chaidamu vortices, characteristic, forecast
