开封市一次暴雨的数值预报效果检验

摘要

利用EC模式和T639模式对2010年7月17-19日开封市暴雨进行了模拟,并将模拟结果与实况进行对比,发现两种模式在降水的落区和强度上均有较好的表现.在动力场和风场上的模拟结果虽然与实况略有偏差,但主要的降水系统与相差不多.与中尺度模式MM5的模拟结果则表明,在短期临近预报中,中尺度模式的效果更好.%By using EC model and T639 model, this paper simulated:the Kaifeng rainstorm on 17-19 July 2010, and the simulation results compared with the fact, show that the area and intensity of the two modes have better performance. In the power field and wind field simulation results and live a little bias, but the main precipitation system with similar. The simulation results with the mesoscale model MM5 show that in the short-term nowcasting, the mesoscale model will be better
