Miles Several topics dealing with geophysical fluid dynamics considered to be basic to the physical understanding of important phenomena in both the ocean and the atmosphere will be studied using analytical methods. Of primary interest are the effect of gustiness and parameterization of surface roughness on win to wave energy transfer, non-linear effects of wave age on effective roughness, wave propagation in water of variable depth, internal vs. boundary layer damping for surface waves, and the dissipation of barotropic (surface) tidal energy through conversion to baroclinic (internal) tides.

涉及地球物理流体动力学的几个主题被认为是对海洋和大气中重要现象的物理理解的基础，将使用分析方法进行研究。主要关注的是阵风和表面粗糙度的参数化对波浪能量传递的影响，波龄对有效粗糙度的非线性影响，波在变深度水中的传播，表面波的内部与边界层阻尼，以及正压（表面）潮汐能通过转换为斜压（内部）潮汐的耗散。
