Improving Mesoscale Prediction of Shallow Convection and Cloud Regime Transitions in NRL COAMPS

Abstract

Accurate predictions of cloud and precipitation processes in the marine boundary layer are critical to U.S. Navy operations, as well as being more broadly important to improving seasonable predictability and the performance of NWP models. The major goal of the project is to develop and test state-of-the-art boundary layer and microphysical parameterizations in order to better represent the continuum of cloud regimes from stratocumulus to trade cumulus, with particular emphasis on cloud regime transitions. Accurate prediction of cloud-topped marine boundary layers regional forecast models is currently hindered the ability of the models to represent shallow cumulus boundary layers and transitions between different cloud regimes.
