| 中文摘要:利用中尺度模式WRFV3.5中常用的云微物理过程参数化方案，对河南省3次典型强天气过程进行敏感性试验。结果表明：不同微物理方案对过程降水的预报效果存在差异，随着模拟降水量级的增大，各方案之间的差异也随之增大。模拟效果相对较好的方案存在不确定性，在所选过程的模拟中没有哪种云微物理方案明显优于其他方案。相对地，WSM6类冰雹方案在所选的局地干、湿对流过程中能更合理地表现出强降水量级、范围及落区。对于“2007-07-29”卢氏暴雨过程，采用WSM6类冰雹方案的模拟效果最理想，WSM3方案模拟效果次之，Thompson和Lin方案的模拟效果最不理想。对于“2011-06-24”豫西局地强风雹过程，3种相对复杂的微物理方案模拟结果差别不大，相对地，WSM6类冰雹方案模拟效果优于其他方案的，Lin方案的模拟效果相对较差。“2006-06-25”豫西北飑线过程的模拟结果表明，各方案虽不能完美再现飑线的影响时间、范围及其结构特征，但每种方案均有其自身特点且能表现出部分细节特征。相比于WSM6类冰雹方案和Thompson方案，Lin方案模拟结果在影响时段、范围及飑线结构等方面表现得更理想。 |

| Abstract:Sensitivity tests of 3 typical processes in Henan province are made with different cloud microphysical parameterization schemes in WRFV3.5. The results show that: there are differences in precipitation forecast effect with different microphysical parameterization schemes and they increase as the amount of precipitation goes higher. The selection of relatively suitable scheme exists uncertainty. In the simulations of selectedprocesses, there are no schemes obviously better than the others. Relatively, the WSM 6-class graupel scheme can show relatively reasonable amount, range and falling area of heavy rain in the chosen local dry and moist convection processes. In simulation of “2007-07-29”process, WSM 6-class graupel scheme simulates best, WSM 3-class simple ice scheme performs the second better while Thompson graupel scheme and Lin scheme are the worst.In “2011-06-24”process,the simulation results with 3 relatively complicated schemes have little difference, while the WSM 6-class graupel scheme performs better and Lin scheme relatively worse. The simulation results of “2006-06-25” squall line process show that:although the schemes can’t ideally reconstruct the impact time, area and structure characteristics of the squall line, they all have their own characteristics and can show some detail features separately. Compared to WSM6-class graupel scheme and Thompson graupel scheme, the simulation with Lin scheme are more ideal in terms of impact time, area and squall line structure. |
