9. Anticyclone and local winds

As the name indicates, an anticyclone is the opposite of a cyclone. In an anticyclone, a high-pressure area is formed in the centre surrounded by low pressure. An anticyclone's winds rotate opposite to that of the cyclone, i.e. clockwise in the Northern Hemisphere.

In Anticyclone, the pressure circles' (isobars) pressures decrease by moving away from the centre. The air that comes in from above sinks to the ground. Generally, moderate weather is experienced at the high-pressure centre.

 

Local winds blow over a small area only during a particular time of a day or for a short period of a year. The effect of these local winds are experienced only in that particular area.

They are mostly seasonal and have local names.
