anticyclone etymology

Etymology:

• Anticyclone is derived from the Greek words:
  • ἀντί (anti) meaning "opposite" or "counter"
  • κύκλος (kyklos) meaning "circle" or "ring"

Meaning:

An anticyclone is a large-scale atmospheric circulation characterized by high pressure at its center, with the air circulating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

Origin:

The term "anticyclone" was first coined by Francis Galton in 1883. He used the term to describe a counter-rotating atmospheric circulation that formed over the North Atlantic Ocean. Galton's initial definition of an anticyclone included both the high-pressure region and the surrounding area of descending air.

Over time, the term "anticyclone" has come to specifically refer to the high-pressure region at the center of the circulation. The surrounding area of descending air is now typically referred to as a subsidence inversion.

Characteristics:

Anticyclones are typically associated with:

• Clear skies and calm winds
• Stable atmospheric conditions
• Warm, dry, and shallow air
• Slow-moving weather systems
• Light precipitation (if any)

Anticyclones form due to a combination of heating and cooling in the atmosphere, as well as the rotation of the Earth (Coriolis force). They are often found in the subtropics and over the oceans.
