PHYSICAL MATHEMATICS SEMINAR TITLE: INTEGRAL EFFECTS OF EDDIES IN THE LARGE SCALE OCEANIC FLOWS SPEAKER: TIMOUR RADKO EAPS, MIT 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.
