" Oceanic Mesoscale Versus Submesoscale Eddy Variability – Dynamics, Vertical Motion and Satellite Observability"

This presentation will focus on two aspects of mesoscale-submesoscale variability in the subtropical gyre circulation in the North Pacific Ocean. First, we analyze the output from a 1/30-deg high-resolution OGCM simulation and the AVISO gridded satellite altimetry product to contrast the seasonal Subtropical Countercurrent (STCC) variability in the mesoscale vs. submesoscale ranges. Importance of two types of baroclinic instability are emphasized.

The second topic utilizes the theoretical framework of effective surface quasi-geostrophic (eSQG) dynamics and explores the potential of reconstructing the 3D upper ocean circulation features, including the vertical velocity (w) field, from high-resolution sea surface height data expected from the forth-coming NASA-CNES's Surface Waterand Ocean Topography (SWOT) mission.
