Oceanic vortex mergers are not isolated but influenced by the β-effect and surrounding eddies.

Oceanic vortices are ubiquitous in the ocean. They dominate the sub-inertial energy spectrum, and their dynamics is key for the evolution of the water column properties. The merger of two like-signed coherent vortices, which ultimately results in the formation of a larger vortex, provides an efficient mechanism for the lateral mixing of water masses in the ocean.

Interaction of the Gulf Stream with small scale topography: a focus on lee waves.

The generation of lee waves in the Gulf Stream along the U.S. seaboard is investigated using high resolution realistic simulations.
