Global Cloud Resolving Model Simulations toward Numerical Weather Forecasting in the Tropics

Research Project Outline

The global cloud resolving model which simulates the global atmospheric circulation with 3.5km-horizontal mesh is now available using the Earth Simulator. This model explicitly resolves cumulus convection whose horizontal scale is a few kilometers; the effects of cumulus convection is poorly representated in existing global circulation models. In this study, we explore its cloud and precipitation behaviours especially in the tropics and investigate scientific and technical problems to use it as a numerical weather forecasting model.
