Abstract:
In the high resolution model (6 to 3 km), there are still controversies for using the cumulus parameterization scheme. The impact of using different cloud precipitation schemes on the simulation of a hurricane is studied by using the WRF model at a grid spacing of 5 km, and the causes of the impact are investigated. The results indicate that even in this high resolution, the cumulus parameterization scheme can improve the simulations of TC tracks. The sophisticated mixed ice phase schemes have the greater advantage of simulating the TC tracks than the simple mixing ice phase schemes. The simulation of TC intensity is sensitive to the choice of cumulus parameterization schemes. The best simulation of precipitation can be obtained by employing only the microphysics scheme. Using the cumulus parameterization scheme can cause more false rainfall, but improve the simulation of the third day precipitation. By affecting the simulations of the typhoon asymmetrical structure, the cumulus parameterizations can improve the simulations of TC tracks. These findings provide a reference for typhoon simulation by using the high resolution model and improve the cumulus parameterization scheme.
