Description
The WRF-ARW model with high resolution was employed for the real-time forecast during the Midlatitude Continental Convective Clouds Experiment (MC3E) field campaign (April 22–June 6, 2011) over the SGP site. The model features new Goddard microphysics (Lang et al. 2011) and Goddard radiation schemes and runs twice a day with 00Z and 12Z forecast cycle.
The objects for the post-mission simulations are: (1) improving WRF model simulations with different model configuration and input data resources, (2) validating model results with available observational data sets, and (3) investigating the effects of key physical processes (microphysics, radiation, surface fluxes, and terrain) on model simulations.
In this poster, we will present the simulation results of three cases from MC3E: April 25–26, May 20, and May 23. A significant improvement in depicting the May 20 squall line event is found by coupling WRF with Land Information System (LIS), indicating the importance of a more realistic representation of land-surface processes on simulating midlatitude mesoscale convective systems. The simulation will be compared with ground-based radar observations and also will incorporate Goddard Satellite Simulator Unit (GSDSU) to compare with satellite products (TRMM PR and AMSR-E).
