Despite rapid advances in numerical weather prediction models and ever increasing computational capability, our ability to accurately predict various severe weather phenomena in the short range and at the mesoscales remains limited. This talk will present an overview of recent progress in our understanding of the mesoscale predictability of various severe weather phenomena, including summertime mesoscale convective systems, tropical cyclones, and wintertime snowstorms, using both real-data studies and idealized simulations.

Despite the inherent limit of mesocale predictability, there is still significant room for improving the practical predictability of severe weather and tropical cyclones through advanced data assimilation techniques, better use of exiting or future observations, and improved forecast models. Inter-comparison and coupling of various variational and ensemble-based techniques for both severe weather and tropical cyclones will also be presented.

Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.

The University of Oklahoma is a smoke-free / tobacco-free campus.
