Coastal Trapped Waves Around the Hawaiian Islands

这个项目将调查海洋对岛屿附近风力的反应。预计岛屿困波（ITW）将在数天至数周的时间内成为这一响应的重要组成部分。现有的海平面、流计和天气观测将用于检查夏威夷群岛周围ITW的运动学、结构和动力学。越来越复杂的分析模型将用于阐明基本的物理原理。现有的数值模型，修改包括地形增加真实感，将用于模拟。预计ITW将远距离传输能量，促进局部上升流和下升流，并扰乱更深的流动。因此，提高对ITW的了解将有利于航运和渔业，并改进对岛屿附近污染物扩散的预测。由于现在可供分析的数据集范围扩大，该项目特别及时。* * *

9522092 Luther This project will investigate the oceanic response to wind forcing in the vicinity of islands. It is expected that Island Trapped Waves (ITW) will be an important part of this response at periods of days to weeks. Existing sea level, current meter, and weather observations will be used in the examination of the kinematics, structure, and dynamics of ITW around the Hawaiian Islands. Analytical models of increased complexity will be used to elucidate basic physical principles. Existing numerical models, modified to include topography of increasing realism, will be used for simulation. ITW are expected to transmit energy over long distances, contribute to local upwelling and downwelling, and perturb deeper flows. Thus, an improved understanding of ITW would benefit shipping and fisheries, and improve predictions of contaminant dispersal in the vicinity of islands. The project is particularly timely due to the increased scope of the data sets now available for analysis. ***
