NOVEMBER 2003 AMERICAN METEOROLOGICAL SOCIETY | L ogistical and scientific operations in Antarctica are critically dependent on numerical weather guidance. The extreme, unforgiving environment amplifies the risks stemming from poor forecasts, while the sparse observing network often leaves forecasters heavily reliant on numerical weather prediction (NWP). To the operation of real-time mesoscale...
Several aspects of modeling dynamics at the mesoscale level are discussed: (1) The construction of a mesoscopic description of fluid dynamics. The mesoscale dynamics consists of free streaming interrupted by multi-particle collisions. The multi-particle collisions are carried out by performing random rotations of particle velocities in predetermined cells in a manner that conserves mass, moment...

[1] Mesoscale variability where the East Australian Current (EAC) separates from the coast is studied using sea surface temperature and surface velocity streamfunction observed by satellite and a regional numerical model. The mean circulation simulated by the model (the Regional Ocean Modeling System (ROMS)) is compared to a high-resolution regional climatology, and the realism of the simulated...
Integrated modeling of aerosol, cloud, precipitation and land processes at satellite-resolved scales
In this talk, I will present recent results from a project led at NASAfGSFC, in collaboration with NASAfMSFC and JHU, focused on the development and application of an observation-driven integrated modeling system that represents aerosol, cloud, precipitation and land processes at satellite-resolved scales. The project, known as the NASA Unified WRF (NU-WRF), is funded by NASA's Modeling and Ana...
