The Penn State/NCAR Mesoscale Model 5 (MM5) includes parameterization for the surface and planetary boundary layer, and cloud microphysics. It also includes prediction of rain water/snow, cloud water/ice and graupel, cumulus convection, and atmospheric radiation.
The ability to predict the behavior of large storm systems is an important and necessary tool for helping save lives and property that can be lost during severe weather events. The MM5 numerical model is used here to simulate the structure and evolution of an East Asia coastal cyclone that occurred in June of 1993.
Typhoon Herb roared across northern Taiwan resulting in the loss of many lives and damage to property due to high winds, flooding, and landslides. Researchers are using advanced computer models and high resolution radar data to study this complex and deadly storm system. This visualization shows a comparison between the observed and model data.
This model simulates a complete eyewall with multiple rain bands with a structure similar to the radar analysis.
Simulation of Hurricane Diana Genesis
This simulation marks the first time a cloud-resolving simulation has been able to reproduce the formation of a tropical cyclone, given only information about atmospheric conditions on a scale much larger than that of the cyclone.
