| 摘 要： | 利用NCEP/NCAR再分析资料驱动中尺度天气模式MM5和WRF,模拟2005年4月6日辽宁强雷暴降水天气过程。结果表明:MM5和WRF模拟雷暴发生的天气系统结构相似,但对于降水量模拟,WRF模式模拟的结果与实况更为接近。分析其天气系统结构表明,降水过程中来自不同地区的冷暖空气交汇和来自不同地区云团的汇合造成了此次强雷暴天气的发生。

| Abstract: | Based on NCEP/NCAR data,the strong thunderstorm weather process on April 6,2005 in Liaoning province was simulated by MM5 and WRF models.The results showed that the simulations of weather system structures by MM5 and WRF models were similar,while the simulations of precipitation by WRF model were closer to the observation.According to the weather system structures,the convergence of cold and warm air and cloud clusters from different regions in rainfall process resulted in the strong thunderstorm weather process. |
