Abstract:

The main objective of this article is to study the double-gyre
phenomena of the mid-latitude Atlantic ocean from the numerical and
structural analysis points of view.  A wind-driven, double-gyre,
mid-latitude, quasi-geostrophic ocean model is adopted.  An efficient
and accurate spectral-projection method is developed and implemented
for this model. A number of numerical simulations are carried out and
their structural stability and structural transitions/bifurcations are
investigated using a new dynamical systems theory of two-dimensional
incompressible flows.
