报告摘要：In this talk, we shall study the well-posedness, blowup in a finite time, and the backflow phenomenon of the geophysical boundary layer problem, in the large Reynolds number and beta parameter limit of the oceanic current motion at midlatitudes under the action of wind and the Coriolis force. In contrast with the classical Prandtl boundary layer equation, the geophysical boundary layer equation has an additional integral term arising from the Coriolis force. By analysis, we find that this integral term triggers the formulation of singularities earlier, comparing with the corresponding results of the classical Prandtl equations. This is a joint work with Xiang Wang.
