Modeling Open-Ocean Deep Convection
LONG-TERM GOALS. To understand the convective process in the ocean, develop numerical models to study it, and so improve the representation of convection in ocean circulation models. OBJECTIVES. To understand the relative importance of vertical mixing by convection and lateral advection by geostroph...
