Geophysical Fluids and Mathematical Issues

The study of geophysical fluids presents many challenges to mathematicians. The full primitive equations are too general to be even appropriate for numerical simulations. Simplified models are needed that still capture the key features of a specific oceanic, or atmospheric, phenomenon. This is a problem in partial differential equations that can be, on account of conserved quantities, be posed in the Hamiltonian framework.

The Lagrangian view of fluid motion is particularly important in oceanography since only Lagrangian data can be obtained from sub-surface motion. The problem of assimilating such data into numerical models is thus of great practical significance. Lagrangian mixing poses many problems in dynamical systems. Since the only realistic models are numerical, this area involves incorporating the theory of geophysical fluids, computations and analysis.
