Two-Way Coupled Model Studies of Diurnal Convection Over the Tropical Pacific.

摘要

Our long-range objectives are to encourage and facilitate the incorporation of improved aerodynamic bulk formula into operational marine forecast models and demonstrate the marine forecast sensitivity to coupled boundary layer parameterizations. The main objective of this proposal is to explore the physical processes of the air-sea coupling that may be responsible for accurate simulation of tropical convective cloud systems and SST on the diurnal to synoptic time scales over the western Pacific warm pool. In this exploratory study we propose to examine the model sensitivity to an interactively coupled non-advective upper ocean mixed layer model with a full three-dimensional high resolution atmospheric model. We will explore how changes in the coupled boundary layer parameterizations and two-way air-sea coupling may impact forecast fields.
