Abstract.
The basic problem faced in geophysical fluid dynamics is
that a mathematical description based only on fundamental physical
principles, the so-called the ``Primitive Equations'', is often
prohibitively expensive computationally, and hard to study
analytically. In this talk I will survey the main obstacles in
proving the global regularity for the three-dimensional
Navier--Stokes equations and their geophysical counterparts. Even
though the Primitive Equations look as if they are more difficult to
study analytically than the three-dimensional Navier--Stokes
equations I will show in this talk that they have a unique global
(in time) regular solution for all initial data.
