Single-column model and cumulus ensemble model simulations of GARP Atlantic Tropical Experimental Data

This ARM project consists of developing and demonstrating improved cloud formation parameterizations by using both a single-column model (SCM) and a cumulus ensemble model (CEM), together with ARM data. These two models can be driven with large-scale forcing. The SCM does so through its physical parameterizations, while the CEM does so by directly simulating convective cloud circulations. To further test these improved parameterizations, progress in the following areas is discussed: Develop improved cloudiness parameterizations; Develop improvements to the CEM, with emphasis on cloud-radiation interactions; Drive both models with ARM data; Transfer the improved parameterizations developed in this way to the CSU general circulation model (GCM)
