Effects of Wind on Convection in Strongly and Weakly Baroclinic Flows with Application to the Labrador Sea*
ABSTRACT
Large buoyancy loss driving deep convection is often associated with a large wind stress that is typically omitted in simulations of convection. Here it is shown that this omission is not justified when overturning occurs in a horizontally inhomogeneous ocean. In strongly baroclinic flows, convective mixing is influenced both by the background horizontal density gradient and by the across-front advection of buoyancy due to wind. The former process-known as slantwise convection-results in deeper convection, while the effect of wind depends on the relative orientation of wind ...
