Abstract

The evaluation of the improved convective triggering mechanism in community atmosphere model (CAM2) under the Climate change prediction program (CCPP)- Atmospheric radiation measurement program (ARM) Parameterization Testbed (CAPT) framework, in which the climate model is run in Numerical Weather Prediction (NWP) mode, is discussed. The triggering mechanism introduces a dynamic constraint on the initiation of convection. It is observed that the model with the triggering mechanism can effectively reduce the problem associated with the overreactive convection in the original model. This results in a more realistic precipitation field simulated by the model.
