Study of an Elliptic Partial Differential Equation Modeling the Ocean Flow in Arctic Gyres

open access: yesJournal of Mathematical Fluid Mechanics, 2021
We study the ocean flow in Arctic gyres using a recent model for gyres derived in spherical coordinates on the rotating sphere. By projecting this model onto the plane using the Mercator projection, we obtain a semi-linear elliptic partial differential ...

Study of an elliptic partial differential equation modelling the Antarctic Circumpolar Current

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2019
We consider the ocean flow of the Antarctic Circumpolar Current. Using a recently-derived model for gyres in rotating spherical coordinates, and mapping the problem on the sphere onto the plane using the Mercator projection, we obtain a boundary-value ...
