A large-scale atmospheric circulation system characterized by high pressure at its center, with air flowing outward and clockwise in the Northern Hemisphere. Anticyclones typically bring clear skies, calm weather, and stable atmospheric conditions.
From Greek 'anti' meaning 'opposite' and 'cyclone' (from Greek 'kyklon' meaning 'moving in a circle'). The term was coined in the 1860s when meteorologists recognized this weather pattern as the opposite of cyclonic systems.
