Abstract:

The long-term goal of this PI team is to understand the physical processes of the air-sea interaction and coupling of the atmosphere-ocean system in high-wind maritime regimes, with a particular emphasis on hurricanes. One of the most complex aspects in the air-sea coupling is the effect of surface waves at the air-sea interface that is not clearly defined in the high-wind conditions. We aim to determine the changes that must be made to the coupled atmosphere-wave-ocean models in order to simulate the coupled boundary layers under extreme wind conditions. The main objectives of this study are 1 to develop and test new parameterizations of wind-wave coupling in high wind conditions, 2 to improve hurricane intensity forecasts in a high-resolution, fully coupled atmosphere-wave-ocean modeling systems, 3 to test the sensitivity of mixing schemes in the ocean mixed layer OML and examine the effects of the ocean waves on the OML dynamics, and 4 to develop atmosphere-wave and atmosphere-ocean generic couplers to allow the flexibility of testing various physical parameterizations.
