anticyclone
Clear skies bringer
An anticyclone is a weather system in which winds rotate around a center of high atmospheric pressure—clockwise in the Northern Hemisphere, counterclockwise in the Southern.
Anticyclones typically bring clear, calm weather, in contrast to cyclones, which produce storms.
A stubborn anticyclone kept the skies sunny all week.
