Abstract: This paper is mainly about the performance verification and comparative analysis of three precipitation processes in July 2014 in Shanxi through the T639 model, EC model, Japan model and NECP model. In order to better interpret and apply the forecast products of numerical model, the verification and analysis were based on the objective analysis and ETS score method. The results showed that the four models had good performance in forecasting the large-scale circulation evolution and the adjustment of Eurasia in high latitude circulation and the ground system. The four numerical models had good forecast in basic direction of the rainfalls and fall area, but their forecasts in precipitation intensity and the stability of the heavy rain center were worse than the actual situation. For the ETS score, the score of the NECP model was higher in all the three rainfall processes, and the 24 hours forecast effect of different numerical models was superior to other forecast validity. Overall, EC model is the best for the evolution of the circulation form, followed by NECP model, and T639 model and Japan model take the last place; NECP model is more accurate for the forecast of precipitation and fall area than the EC mode, while the forecast stability of the T639 model and Japan model are poor. So NECP model has the high reference value, it can be used in the actual forecast operation.
