Abstract: O(100 km) scale vortices, known as mesoscale eddies, contain more than 90% of the kinetic energy in the world's oceans. Although energy sources of these large scale long lived vortices are more or less well understood, oceanographers have not yet figured out the mechanisms by which these vortices lose their energy. This talk will explain my work exploring the possibility of fast internal gravity waves, generated by atmospheric winds and lunar gravitational tides, acting as an energy sink for slowly evolving vortices in the world's oceans.
