Submesoscale coherent vortices
From Glossary of Meteorology
submesoscale coherent vortices
(Abbreviated SCV.) Isolated, long-lived eddies, having spatial scales smaller than mesoscale eddies; usually anticyclonic, having a geopotential maximum and stratification minimum in the center, with a velocity field having an interior maximum.
SCV types include thermocline SCVs, subthermocline SCVs, Meddies, Arctic Ocean SCVs, and others.
