Abstract: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.
