A Three-Dimensional Mesoscale Model for the Simulation of Clouds, Precipitation and Airflow.

Abstract

A simulation of a heavy rainfall event has been carried out over southern France using 2-D Neph data to initialize a meso-alpha model. That model was subsequently run for a period of three hours and the resulting meteorological fields were then interpolated to a smaller grid to provide balanced initial conditions for a meso-beta model with parameterized microphysics. The meso-beta model is shown to be capable of simulating many features of an orographically forced precipitation event, including the temporal and spatial evolution of liquid water, as well as the number concentration (and hence size distribution) of raindrops. The model is especially suited for the simulation of clouds, precipitation, and airflow over complex terrain. Keywords: Numerical weather prediction; Mesoscale models; Atmospheric precipitation; NOAA; Clouds.
