ARM Parameterization Improves Simulation of Precipitation
Published: April 18, 2005
Posted: April 29, 2005

The addition of a new ARM-developed parameterization on convection into the Community Atmosphere Model (known as CAM3) has resulted in a remarkable improvement in the simulation of climate and its variability on intra-seasonal timescales in the Tropics. In particular, several long-standing model biases are eliminated. The new parameterization improved simulations for precipitation in both winter and boreal summer seasons and more accurately simulates the annual cycle of the monsoon precipitation. The new convection parameterization also improves the simulation of tropical intra-seasonal variability.
