- Agulhas — A geographical proper name denoting Cape Agulhas (Cabo das Agulhas), the official southernmost tip of the African continent located in South Africa, marking the dividing line between the Atlantic and Indian Oceans; the term also names the famous warm western boundary ocean current (Agulhas Current) flowing southward along the east coast of Africa.
- Anticyclone — A large-scale atmospheric formation characterized by an area of high barometric pressure (barometric maximum), where values decrease from the center toward the periphery. This structural phenomenon induces a divergent movement of air masses, which circulate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere, typically being associated with stable, clear weather, devoid of precipitation, or with the formation of thermal inversions during winter.
- Anticyclonic — Pertaining to an anticyclone, specific or characteristic of high atmospheric pressure systems; rotating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere. In synoptic meteorology, the term describes stable weather regimes, descending air movements (subsidence), and wind mass circulation around a barometric maximum.
