Anticyclone and other pressure system 2/M John Jaromahum

Cyclone characterized by rapid inward circulation of air masses about a low-pressure center, accompanied by stormy, destructive weather. counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

Anticyclone A region of relatively high atmospheric pressure thousands of kilometres in diameter. appear on weather charts as a series of concentric, widely spaced isobars of 1000 mbs and above. clockwise in the Northern Hemisphere, and anticlockwise in the Southern also known as a high.

NORTHERN HEMISPHERE

Weather in Anticyclones Varies from place to place

Weather in Cold anticyclones also known as continental highs Siberia and north-west Canada in winter Cool air

Weather in Subtropical anticyclones stable atmospheric conditions, and thus, fine, hot, dry weather. Strongest at 32° N and S.

Weather mid-latitude anticyclones located beneath the leading edge of ridges in the upper-air westerlies the weather is unusually fine

Winter anticyclones may bring cold, frosty weather, or fog.
