Gwyn Evans

Gwyn is a physical oceanographer based at the National Oceanography Centre (NOC), Southampton. Gwyn is interested in the dynamics of the ocean on a range of spatial and temporal scales, and in particular the roles of diabatic and adiabatic process in driving the global overturning circulation using water mass transformation frameworks in observational- and model-based data.

Why do mesoscale eddies disappear at ocean western boundaries?

Why do mesoscale eddies disappear at ocean western boundaries?

In the ocean, mesoscale eddies are everywhere. In fact, about 90% of the ocean’s kinetic energy is contained within these ubiquitous, ~100 km swirling vortices. We know how these eddies form, through a process known as baroclinic instability, where density surfaces are tilted too steeply and become unstable. What remains unclear however, is what happens to this energy when eddies die. This knowled ...[Read More]
