Abstract

The Global Cloud-Resolving Model is a next-generation atmospheric global model with potential to open up new areas in numerical weather forecasting and climate simulation. The new model, called NICAM, has shown realistic behavior for precipitation systems over the global domain, particularly over the tropics. One impact of the global cloud-resolving model is the attainment of realistic simulation of rainfall in the tropics realizing a multiscale nature from kilometer to planetary, because rainfall in the tropics affects short-term local tropical weather and the long-term global climate. We review the global cloud-resolving model using simulation results from NICAM, and discuss its applicability in reducing natural weather disasters.
