Nonlinear Waves in the Ocean and Atmosphere and Numerical Algorithms

9986368这是一个多学科项目，旨在研究海洋和大气中的各种非线性波过程，并试图改进一些用于模拟地球物理流体动力学的数值方法。前者是与大气科学和海洋科学有关的问题，包括斜压波包、热带不稳定波和中尺度（大气意义上的）孤立内重力波。此外，PI将解决与地球物理问题中使用的一些光谱和谱元代码相关的计算数学问题，特别是滤波和兼容性条件的问题。

9986368This is a multi-disciplinary project to examine a variety of non-linearwave processes in the ocean and atmosphere as well as attempting to refine some of the numerical methods used to model the dynamics of geophysical fluids. The former are problems relevant to both atmospheric and oceanic sciences and include baroclinic wave packets, tropical instability waves, and mesoscale (in the atmospheric sense) solitary internal gravity waves. In addition, the PI will address computational mathematics issues associated with some of the spectral and spectral-element codes used in geophysical problems, particularly the issues of filtering and compatibility conditions.
