Final states of two-dimensional turbulence above large-scale topography: stationary vortex solutions and barotropic stability
Jiyang He, Yan Wang
The final states of freely decaying two-dimensional (2D) topographic turbulence consist of a background flow and localized vortices. While the background flow satisfies a linear po…

Zonal flows driven by libration in rotating spherical shells: the case of periodic characteristic paths
Xu Chang, Jiyang He, Benjamin Favier +1
This work investigates the weakly nonlinear dynamics of internal shear layers and the mean zonal flow induced by the longitudinal libration of an inner core within a spherical shel…

Internal shear layers generated by a vertically oscillating cylinder in unbounded and bounded rotating fluids
Jiyang He, Benjamin Favier, Stéphane Le Dizès
In rotating fluids, the viscous smoothing of inviscid singular inertial waves leads to the formation of internal shear layers. In previous works, we analysed the internal shear lay…
