| 摘 要： | 本文使用中尺度数值模式WRFV3.4中的8种不同云微物理过程参数化方案，模拟2010年5月6～7日华南一次暴雨事件，探讨不同云微物理方案对华南暴雨模拟的影响。结果表明:不同云微物理方案对不同量级降水模拟效果总体较好。WSM3方案对小到大雨和大暴雨的模拟效果最好，对暴雨的模拟最差；WDM5方案对暴雨模拟效果最好。结合TS评分和误差分析结果，整体效果最好的是WSM5方案，最差的是Lin方案。对于同一云微物理参数化方案，不同分辨率的降水模拟结果差异不大，但同一分辨率的不同云微物理参数化方案的降水结果差异较大，这说明云微物理过程比模式分辨率对暴雨模拟的影响更大。

| Abstract: | In this study, eight cloud microphysics parameterization schemes (schemes Kessler, Lin, WSM3, WSM5, Eta, WSM6, WDM5, and WDM6) in the weather research and forecasting (WRF) model were used to simulate a rainstorm that occurred over South China during May 6-7, 2010, to study the effects of the cloud microphysics parameterization schemes on the simulation ability of the rainstorm. A comparison of the experimental results with the observation revealed an overall agreement in the simulation skills of various cloud microphysical schemes to various precipitation scales. The WSM3 schemes performed best for light to heavy rainfall and downpours. For simulating the rainstorm, however, WDM5 performed best, and WSM3 performed worst. According to the analysis results of threat score (TS) and error, the WSM5 scheme performed best, and the Lin scheme was worst. One parameterization scheme showed a small difference among various resolutions and a large difference in the simulation ability of the rainstorm among various microphysics parameterization schemes, which suggests that cloud microphysics parameterization schemes are more effective than resolution for simulating heavy rain. |
