The potential prediction of 0 to 12 hours is conducted for strong convective weather based on MM5 and the diagnosis of instability and energy indexes. The stormtracing information of Doppler radar is used in the 0 to 1 hour nowcasting of strong convective weather. The stormtracing information contains the motion direction and velocity of radar echoes. By means of the trial use in severe convective processes, the comparison is made between prediction and real condition. The experiments are conducted on some strong convective weather events in recent years with the shortterm potential prediction method. The results show that both methods are valuable in forecasting strong storms.
