Sensitive Experiment of Meiyu Front Rainstorm in Different Physics Processes
Abstract：Based on a Meiyu front rainstorm of Jianghuai region in July 2005, it is simulated with two grids by different physics processes and the result is analyzed.It shows that all schemes can simulate the direction of the rain and the center of the precipitation,but the two schemes（New-Kain-Fritsch and Ferri er;Betts-Miller-Janjic and Ferrier） are consistent with the actualities;the si mulation of Ferrier is good in the initial stage,the simulation of Lin is good in the latter stage;when microphysical schemes are same,the changes of cumulus convective parameterization schemes impact on vertical velocity,pseudo-equiva lent potential temperature,and relative humidity are obvious;some cumulus conv ective parameterization scheme in wide grid is able to reproduce meso-α-scale vortex features.
