Influenced by the relief, these winds blow through the Ganga valley from west and north west, which forms an anticyclonic condition in northern part of India.
Anticy systems characterized by a central area of high pressure surrounded by closed boblari, with pressure docreasing outward. Air Rows outward because winds are deflected by the Coriolu forte to the right in the Northern Hemisphere and to the left the Southern Hemichere. centre, rotating clockwise uthern Hem rmation occurs
pressure the centre and periphery of an anticyclone is usually 10-20 mh, though it can be higher. Anticyciones are larger than tamperate cyclones, often about 75% wider, covering a ach larger area.
Temperate anticyciones are particularly expensive, sometimes covering nearly half of the United States. They can shit direction frequently and may remen in one location for up to four days, moving at an average speed of 30-50 km/h
Anticycranes form when either cold polar ar or warm tropical ar sinks from the upper atmosphere to the lower atmosphere. These systems are mast commonly found in sutitropical and polar regions and are almost never present near the equator.
