物理过程参数化方案对加勒比海台风模拟的影响

针对大气模式的多个物理过程，研究不同微物理过程和积云对流参数化方案组合对WRF模拟加勒比海地区台风路径和强度的影响。结果表明：虽然台风路径模拟对于参数化方案组合的选择具有一定的“个例依赖”特性，但综合来看，WSM5-Kessler的组合方案对模拟加勒比海地区台风路径的模拟效果最好，其次是WSM6-Kessler组合。台风强度模拟“个例依赖”特征不明显，以KF积云方案为最优，微物理过程方案对强度模拟影响不明显。

Influence of physics scheme on cyclone simulation in Caribbean area

The numerical model WRF was applied to explore the impacts of different micro-physics schemes and cumulus parameterization schemes on the simulation of the track and intensity of cyclones which influenced Caribbean area.The results showed that even the best combination of parameterization scheme was different for each cyclone on the simulation of the track,the combination of WSM5-Kessler produced the best simulation of the track overall;Secondly,the combination of WSM6-Kessler was better.The simulation results of cyclone intensity are consistent.The result showed that the cumulus parameterization schemes KF was the best,and the effect of micro-physics schemes on the intensity simulation was not obvious.
