Sub-Mesoscale Modelling of the Labrador Sea
We will showcase over a decade of results that illustrate the need for high resolution in this region, particularly as it impacts the spatial and vertical extent of deep convection. Irminger Rings, eddies shed from the west coast of Greenland, are tracked and investigated. These eddies evolve as they travel into the interior of the Labrador Sea, carrying a significant amount of buoyancy that coarser resolution simulations often misrepresent. These eddies, as well as other mesoscale features, influence the production of Labrador Sea Water, an important component of the Atlantic Meridional Overturning Circulation. Four passive tracers have been included and will be discussed: Greenland runoff, Canadian Arctic outflow, Labrador Sea Water produced during convection, and Irminger Water which flows west past Cape Farewell.
