Improving Air-Sea Coupling Parameterizations in High-Wind Regimes
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.
