Coupled WRF-GCE-LIS (High-resolution Weather Forecast Model)

Importance of the microphysics in high-resolution weather forecast models

Microphysical (cloud) processes developed at NASA Goddard were implemented into a next generation of weather forecast model (e.g. WRF). The explicit and realistic representation of microphysics in the high-resolution numerical weather forecast model is crucial for accurate prediction of the midlatitude mesoscale convective systems and the intensity and track of hurricanes.
