Coherent Structures in Geophysical Flow

本研究涉及地球物理流体中模态和其他相干结构稳定性的分析和数值研究。模态是准等转方程在平面上的均匀平移、保形解。这些嵌入湍流中的相干结构是在自然界中观测到的长寿命结构（如大气块体和海洋涡流）的潜在模型。

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.
