高分辨率GRAPES模式中云微物理方案对强降水的模拟和诊断研究
Simulation and Analysis of Heavy Precipitation Using Cloud Microphysical Scheme Coupled with High-Resolution GRAPES Model
摘要
Abstract
In this study,two heavy precipitation processes are simulated using the two-moment cloud mi-crophysical scheme coupled with high-resolution GRAPES model.The scheme is compared with WSM6 scheme,NCEP5 scheme and a variety of observation data to diagnose the prediction performance and ana-lyze the key cloud microphysics process in deep convective precipitation.The simulation study shows that ice phase particles,especially graupel particles,play a leading role on the convection and precipitation in the deep convection clouds and the melting of graupel is the main source of heavy precipitation,while grau-pel distributes rarely in the stratiform precipitation region which is mainly affected by the melting of snow and warm cloud precipitation.The results derived from the two-moment scheme fit better with observa-tions on rain belt direction,precipitation range and intensity.The scheme also has certain advantages on the maximum echo height and strength of convective cells,ice content distribution and cloud anvil struc-ture.However,the ice content and echo height are slightly lower than observations.All these results would provide meaningful support for the improvement and operational application of the two-moment scheme.关键词
