Long‐Lived Anticyclonic Eddies Facilitate Convection in the Greenland Sea Over Multiple Consecutive Winters

Abstract Wintertime open‐ocean convection is a key process in renewing deep water; however, the processes that promote convection on local scale remain poorly understood. We investigate the role of long‐lived anticyclonic eddies in facilitating deep convection in the Greenland Sea using a new model simulation and observations. We find a previously undocumented anticyclonic eddy in the Boreas Basin, in addition to a well‐observed anticyclonic eddy in the Greenland Basin. Both eddies feature year‐round lenses of weak stratification with upper‐domed isopycnals, facilitating convection over multiple winters.
