海洋环流的涡度分析是其动力学的最基础问题之一。 潮振荡占优势的陆架、海湾或河口环流问题,由于其紧密地联系于长期输运过程的描述,故应以水微团的随体平均速度——拉格朗日平均速度来描写;在一个弱非线性斜压浅海系统中,物质输运速度可以用来体现在最低阶近似意义上的浅海环流的速度场。显然,探讨物质输运速度场的涡动力学是一个非常有兴趣的问题。 The vorticity analysis of ocean circulation is one of the most fundamental problems in its dynamics. Tidal oscillation dominated circulation, shelf or bay or estuarine circulation problems, due to its close contact with the description of the long-term transport process, it should be water-based microsatellites with the average speed of the body - Lagrangian average speed description; in a The weak nonlinear baroclinic shallow sea system, the material transport velocity can be used to reflect the velocity field of shallow sea circulation in the lowest order approximation. Obviously, exploring the eddy dynamics of the velocity field of material transport is a very interesting issue.
