Bermuda High

The Azores High, also referred to as the North Atlantic Subtropical High or more rarely, the Bermuda High, is a large semi-permanent center of high atmospheric pressure typically found around the Azores in the Atlantic Ocean, at the Horse latitudes. It forms one pole of the North Atlantic oscillation, the other being the Icelandic Low. The system influences the weather and climatic patterns of vast areas of North Africa, Europe and to a lesser extent, eastern North America. The aridity of the Sahara Desert and the summer drought of the is primarily due to the large-scale subsidence and sinking motion of air in the system.
