Dynamics of the marine atmospheric boundary layer at high wind conditions

The impact of ocean spray on the dynamics of the marine atmospheric boundary layer (MABL) in conditions of very high (hurricane) wind speeds is investigated. To that end a model of the MABL in presence of sea spume spray is constructed. The model is based on the classical theory of the motion of suspended particles in a turbulent flow, where the mass concentration of droplets is not mandatory small. A description of the spume droplets generation in the model assumes that they being torn off from breaking waves are injected in the form of a jet of spray into the airflow at the altitude of breaking crests.
