Abstract:

The generation, dissipation, transfer and cascade of energy in mesoscale eddy field are important in the world ocean energy budget, because mesoscale eddies are widely found, dominate the ocean kinetic energy, and are involved in energy cascade at different scales. Due to limited observations, however, the energy structure of ocean mesoscale eddies and associated dynamic processes of eddy generation and termination remain unclear. Combining with our new results, this paper reviews the results on the amount, distribution, and sources and sinks of mesoscale eddy energy.

Key words: mesoscale eddy, eddy kinetic energy, eddy available gravitational potential energy, dissipation, source and sink
