| 摘 要： | 使用W RF的ARW动力核心模拟台风"珊珊",以研究各种积云参数化方案对于台风路径,强度和降水分布等的影响。研究表明,环境场对积云参数化的选取不敏感,积云参数化对台风的强度和路径模拟有明显的影响,KF方案模拟的台风强度较强,增强过程明显,后期移速偏快。KF和BM J对降水的模拟较好,GD方案不够理想。

| Abstract: | Though the numerical simulation of typhoon "Shanshan"by using ARW of WRF,the path,intensity,precipitation distribution of the typhoon affected by different types of cumulus parameterization schemes were analyzed.The result shows that: Cumulus parameterization schemes are not sensitive to atmospheric environment.but it would affect typhoon's path and intensity evidently during numerical simulation.Scheme KF has the advantage of simulating typhoon's intensity,especially during its growing course,except it would display that typhoon move more faster than normal in the last course.Schemes KF and BMJ are better than GD in precipitation simulation. |
