摘要

本研究探讨了二次切变基本带流作用下，次中尺度地形对气压不稳定性的影响。在β平面近似上，采用准地转模型进行数值模拟，并采用多尺度模型对该问题进行讨论和验证。多尺度框架用于解释中尺度涡流、次中尺度变率和地形效应之间的相互作用。多尺度方法可以用一组只包含中尺度变量的封闭系统来表达控制方程的动态特征。研究发现，中尺度以下地形与气压不稳定性之间的相互作用会影响中尺度变率的某些特征，如促进中尺度涡的形成以及涡的能量和动量传输。

Effect of Submesoscale Topography on Baroclinic Instability Under the Quadric Shear Basic Zonal Flow

This study explores the effect of submesoscale topography on baroclinic instability under the quadric shear basic zonal flow is discussed. On the beta plane approximation, the quasi-geostrophic model is used for numerical simulation, and the multiscale model to discuss and verify this problem. A multiscale framework is used to explain the interaction between mesoscale eddies, submesoscale variability, and topographic effects. The multiscale method makes it possible to express the dynamic characteristics of the governing equations with a set of closed systems containing only mesoscale variables. It is found that the interaction between submesoscale topography and baroclinic instability affects some characteristics of mesoscale variability, such as promoting the formation of mesoscale eddies.

and the energy and momentum transport of eddies.
