Abstract

Deep convection in the Greenland, the Labrador and the Irminger seas, as part of the global ocean conveyor belt (the Atlantic Meridional Overturning Circulation), is an important component of the climate system of the Earth. In situ investigations of interannual variability of the convection depth are challenging due to a small size of convective cells and interannual variations of their locations within the basins. In this work, using ARMOR data-set, which combines in situ and satellite data, the areas of the most frequent occurrence of deep convection in the North Atlantic are refined. It is shown that in the Labrador and the Irminger seas, deep convection (exceeding 1000 m) can develop in any point of a single region, covering almost all the water area of the seas. Within this region there are three sub-regions of the most frequent development of the deep convection. In addition to two traditionally allocated areas in each of the seas, the deep convection often occurs also at the junction of the two seas, south of Cape Farwell. Convection typically reaches its maximum depth in March. In the Greenland Sea deep convection occurs most often in the central and the south-eastern parts of the sea, as well as in the Boreas basin. Convection typically reaches its maximum depth in April.
