Abstract:
The 3D quasi-geostrophic equation is a model used in climatology to model the evolution of the atmosphere for small Rossby numbers.  The surface quasi-geostrophic equation (SQG) is a special case where the atmosphere above the earth is at rest. The evolution then depends only on the boundary condition, and can be reduced to a 2D model.  In this talk, we consider the full 3D QG and describe recent progress on the questions of both non-uniqueness of weak solutions and existence of strong and weak solutions on cylindrical domains.  In each setting, the boundary conditions will play a crucial role.
