This is one of seven regions of year-round relatively high pressure where barometric values are typically higher than adjacent areas and where the air is drier, skies clearer, and surface wind speeds slower. The other six regions are the Siberian (Asiatic), Pacific (Hawaiian), and North American (Canadian) Highs in the northern hemisphere, and the Indian Ocean, South Atlantic (St Helena), and South Pacific Highs in the southern hemisphere.
The Azores (or Bermuda) High is a large subtropical anticyclone centered between 25°N and 35°N in the Atlantic Ocean. The high often extends westward as far as Bermuda; when this occurs it is known in North America as the Bermuda High. It extends to great elevations, with deep tropical easterlies on its equatorward side and midlatitude westerlies on its poleward side. This very persistent and quasistationary feature of the atmosphere’s circulation is elongated in an east-west direction, with its center of highest pressure located over the eastern...
