Description

Cloud-resolving models have been applied to various atmospheric phenomena and recognized as an effective tool to evaluate and develop its parameterizations. We examine the cloud-resolving simulations performed by the Weather Research and Forecasting (WRF) model in conjunction with the forcing framework developed in the FAst-physics System TEstbed and Research (FASTER) project. The simulations are driven by time-varying, continuous large-scale and surface forcings derived from the observation during March 2000 Cloud IOP at the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site. The simulation is evaluated against cloud properties obtained through the ARM observations. Sensitivity studies to WRF’s physics schemes and nudging strategies are also examined.
