Coherent Structures in Geophysical Flow

这项研究涉及对地球物理流体中的调制子和其他相干结构的稳定性的分析和数值研究。模子是贝塔平面上准地转方程解的一致平移、保形。这些嵌入在湍流中的相干结构是自然界中观察到的长寿命结构的潜在模型，例如大气块和海洋涡流。

This research involves analytical and numerical study of the stability of modons and other coherent structures in geophysical fluids. Modons are uniformly-translating, form preserving solutions of the quasigeostrophic equations on the beta-plane. These coherent structures imbedded in a turbulent flow are a potential model for long-lived structures observed in nature such as atmospheric blocks and oceanic eddies.
