The numerial prediction model of the local torrential rain enhancement is an operationalsystem of regional numerical prediction and the established system is to be realized on localstation's microcomputers.The model is introduced from Lanzhou Plateau Atmosphere Institude to this observatory.The contrast experiment of the numerical model has been done inthe mean time.It was processed in batches during the plum rain season from 15th June to15th July in 1994.The result shows that the model runs with no problems,the calculation isstable.It possesses certain ability to precipitation forecasts.
