On Turbulent Behavior of the Generalized Surface Quasigeostrophic Equations
Chengzhang Fu, Michael S. Jolly, Anuj Kumar +1
Turbulent behavior of the two-parameter family of generalized surface quasigeostrophic equations is examined both rigorously and numerically. We adapt a cascade mechanism argument…

Reconstruction of wide spectrum forcing in transport-diffusion and Navier-Stokes equations
Jochen Bröcker, Giulia Carigi, Tobias Kuna +1
This article considers the problem of reconstructing unknown driving forces based on incomplete knowledge of the system and its state. This is studied in both a linear and nonlinea…

Averaging principle for the stochastic primitive equations in the large rotation limit
Quyuan Lin, Rongchang Liu, Vincent R. Martinez
It is known that the unique ergodicity of the viscous primitive equations with additive white-in-time noise remains an open problem. In this work, we demonstrate that, as the rotat…
