| Abstract: | By using 1°×1°NCEP reanalyzed data with 6 h intervals,the WRF V3.2 meso-scale model is used to simulate the rainstorm process in Zhouqu county on 8 August 2010 with three different cloud microphysical parameterization schemes.The result showed that the forecasting accuracy of numeric simulation is much sensitive to the cloud microphysical parameterization schemes.For precipitation,the Kessler scheme result is closer to the real condition.The simulated physical quantity features with different schemes are different.Therefore,the choice of different schemes may clearly impact the simulated precipitation results.The cloud microphysical features with three different schemes show different results,while the Kessler schemes could basically reappear the cloud microphysical process during the development process of rainstorm. |
