Sensitivity of WRF precipitation simulation to the microphysics schemes:Results from the SoWMEX IOP-8 Case

摘要：

　　The heavy rainfall event on 14-15 June 2008,also categorized as the IOP-8 case,during the SoWMEX/TiMREX field experiment is investigated in this study.The precipitation simulation results using the WRF (Weather Research and Forecasting)model nested down to 1.67 km are compared with the observations from NCAR S-POL and NCU TEAM-R radars during the Mei-Yu frontal system near Taiwan area.Four dimensional data assimilation (FDDA; nudging relaxation) is used on the coarse grids (with grid sizes of 5,15,and 45 km) to capture the large and synoptic-scale forcings.Four microphysics schemes (including the WSM6,WDM6,Thompson,and Morrison) are chosen to compare the simulated microphysics structures.
