TITLE:		INTEGRAL EFFECTS OF EDDIES IN THE 
		LARGE SCALE OCEANIC FLOWS


SPEAKER:	TIMOUR RADKO

ABSTRACT:

We examine effects of the transient eddies for the dynamics of a stratified fluid forced 
by the anticyclonic stress and heated at the surface.  Analysis of several characteristic
large scale flows indicates that the buoyancy and potential vorticity budgets in the presence 
of eddies is dominated by a balance between the vertical advection by Ekman pumping and 
the eddy induced diapycnal fluxes.  Resulting patterns of the statistically steady flow fields are
discussed in terms of a combination of numerical simulations and asymptotic analysis.  
The importance of eddy buoyancy transfer in the western intensification region is emphasized 
by developing a boundary layer theory based entirely on the cross-frontal mass exchange due to eddies.
