* Cyclones: Characterized by low pressure at their center, causing air to converge and rise, leading to cloud formation and often precipitation. They rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

* Anticyclones: Characterized by high pressure at their center, causing air to diverge and sink, leading to clear skies and generally calm weather. They rotate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

Therefore, the commonality between them is their role in the large-scale atmospheric circulation that dictates weather patterns across the globe.
