This project is to study the dynamics of small-scale wind structures in the marine planetary boundary layer off the west coast of the U.S. The marine boundary layer will be modelled by a homogeneous rotating reduced-gravity model to understand the supercritical flow conditions which lead to enhanced upwelling favorable winds. Additionally, the model will be used to study the effects of topography in producing coastally trapped wind reversals. The understanding of these processes should enable better prediction of events in the coastal ocean as a result of better models of atmospheric forcing.

本项目旨在研究美国西海岸海洋行星边界层的小尺度风结构动力学。海洋边界层将采用均匀旋转减重力模型来模拟，以了解导致上升流有利风增强的超临界流动条件。此外，该模式还将用于研究地形对产生沿海困风倒转的影响。由于有了更好的大气强迫模式，对这些过程的了解应该能够更好地预测沿海海洋的事件。
