Anticyclone

Like the cyclone, anticyclone occurs in temperate lands. Unlike cyclones, anticyclones have a high-pressure area at the centre. Wind diverge (i.e. blow outwards) clockwise in the northern hemisphere and anticlockwise in the southern hemisphere, it is the opposite of cyclone or depression.

It is associated with fine weather. Anticyclones generally develop in the high-pressure belts, but sometimes they make inroads into other areas, bringing to those areas fine, pleasant and enjoyable weather, which may last for several days.

Anticyclones are bigger than cyclones and produce, settled and calm weather lasting many days or weeks. Anticyclones often block the path of depressions, either by delaying bad weather or forcing it around the outside of the high-pressure system. This is known as Blocking Highs.

As air descends, air pressure increases. When air reaches the ground level, it has to go somewhere. The earth's rotation causes a change in direction air. In the Northern Hemisphere, the air is pushed clockwise. In the Southern Hemisphere, the air is pushed anticlockwise. This can be seen in the image below (which shows a northern hemisphere anticyclone).
