In order to meet the need of nowcasting，the Doppler radar products were developed and an operational nowcasting display system was set up，which is for monitoring and forecasting weather disasters such as hails and rainstorms in Ningxia. Based on the analysis of the radar observation data and automatic station data，the radar working parameters were adjusted and the function of auto - monitoring，editing and releasing graphic - text files was realized.

Based on routine weather materials and T213 numerical prediction product , the main influence system and the physic
quantities prediction field related to T213 numerical forecast of the first soaking rain process which occurred on May 5 to 6 in 2003 i
Ningxia were analyzed in this paper. The results show that T213 has excellent prediction ability and direction sense to the precipita
tion in Ningxia, and its credibility is improving constantly with shortening of the forecast prescription.
