摘要
在利用WRF模式模拟2015年7月29日内蒙古中部地区一次典型冷涡天气系统影响下的冰雹过程基础上,初步探讨积云(KF、BMJ、GD、G3)和微物理(Lin、WSM6、GM、NT、MYDM7)参数化方案对冰雹模拟结果的影响。液态和固态降水粒子质量浓度时间变化受微物理与积云参数化方案共同影响,水汽、能量以及动力条件主要受积云参数化方案影响。综合考虑不同等级降水的TS评分和呼和浩特市两次对流过程的模拟效果,4种积云参数化方案中,KF表现最优,其次是G3和GD方案,BMJ的模拟效果较差。5种微物理方案中Lin和WSM6模拟效果较好,其中WSM6-KF模拟的降水粒子质量浓度的时间变化、水汽和能量条件以及动力条件的效果最优。
Based on the WRF model,a hail process was analyzed and simulated in central Inner Mongolia on 29 July 2015.The influence of cumulus and microphysics parameterization schemes on hail simulation was discussed preliminarily.The temporal changes of the mass concentration of liquid and solid precipitation particles were affected by microphysics and cumulus parameterization schemes,and water vapor and energy and dynamic conditions were mainly affected by cumulus parameterization scheme.Considering the threat score(TS)of different grades precipitation and the simulation effect of the two convective processes in Hohhot,KF scheme was better,followed by G3 and GD,and BMJ was worse in four kinds of cumulus parameterization schemes.Meanwhile Lin and WSM6 schemes were better in five kinds of microphysics parameterization schemes.WSM6-KF scheme had advantages in simulation of temporal changes of precipitation particles,water vapor and energy and dynamic conditions.
