Randomness, Symmetry, and Scaling of Mesoscale Eddy Life Cycles

Creator:: Samelson, R. M., Schlax, M. G., and Chelton, D. B.
Abstract:: It is shown that the life cycles of nonlinear mesoscale eddies, a major component of low-frequency ocean physical variability, have a characteristic structure that differs fundamentally from that which would be expected on the basis of classical interpretations of ocean eddy evolution in terms of mean flow instability and equilibration...

Satellite Observations of Mesoscale Eddy-Induced Ekman Pumping

Creator:: Gaube, Peter, Chelton, Dudley B., Samelson, Roger M., Schlax, Michael G., and O'Neill, Larry W.
Abstract:: Three mechanisms for self-induced Ekman pumping in the interiors of mesoscale ocean eddies are investigated. The first arises from the surface stress that occurs because of differences between surface wind and ocean velocities, resulting in Ekman upwelling and downwelling in the cores of anticyclones and cyclones, respectively. The second mechanism...
