For a anticyclone to form a air mass must be cooling faster than the surrounding air. This causes the air to contract which in turn makes the air more dense. Because dense air weighs more, the air atmosphere over this area increases causing increased air pressure.

∙ 12y agoIn mid-latitudes, areas of high pressure often take the form of ANTICYCLONES (also called HIGHS). ANTICYCLONES alos tend to be roughly oval in shape.
THEY are often even larger in size than depressions.Pressure is highest at the centre of each ANTICYCLONE.

∙ 13y agoAnticyclones are caused by winds moving down a pressure gradient --- from an area of high to low pressure. In addition, the Earth's coriolis effect gives winds within the high pressure regions a clockwise circulation in the Northern hemisphere and an anti-clockwise circulation in the Southern Hemisphere.

Thunderstorms often form along these fronts. This is how most tornadoes form. Anticyclones generally tend to suppress thunderstorms ans thus tornadoes rather than produce them.

Why don't fronts form in anticyclones?
because they havent got the cheddar cheese required for them to form

What are facts about anticyclones?
# Anticyclones are also known as high pressure systems. # The sinking air in an anticyclone stabilizes the atmosphere, bringing clear, sunny weather. # Anticyclones have anticyclonic rotation, meaning their winds circulate clockwise if they are in the northern hemisphere and counterclockwise if they are int he southern hemisphere. # Anticyclones often form the centers of warm and cold air masses. # Like other large scale weather systems, anticyclones play a key role in steering other weather systems. # Anticyclones can create temperature inversions that trap pollutants near the ground. # Very large anticyclones in the middle latitudes can become blocking highs, halting the normal eastward movement of weather systems. # Two anticylones can produce a low pressure called a trough between them. This trough can develop into a storm system. # Winds between an anticyclone and a cyclone can be especially strong. # Air in a high pressure system flows inward at upper levels and outward at lower levels.
How long do anticyclones last for?
"anticyclones tend to be fairly static once developed and they sometimes persist in the same location in the mid-latitudes for a few weeks. "
What describes both cyclone and anticyclones?
Both cyclones and anticyclones are large storms that travel over water. A cyclone has properties not seen in an anti cyclone such as lower central air pressure and a clockwise rotation.

How do cyclones and anticyclones affect weather?
Cyclones - air cools and clouds form and may cause rainy or stormy weather. Anticyclones - it brings dry and clear weather.
Which characteristic do cyclones and anticyclones have in common?
Isobars form a concentric pattern around the center
What air pressure do anticyclones have?
Anticyclones produce high barometric pressure.
What are anticyclones and depressions?
Anticyclones are high pressure arear and depressions are low pressure areas.
Can anticyclones be affected by climate change?
Anticyclones can be affected by climate change. When air temperature increases it causes clouds to evaporate and anticyclones create dry weather in the summer time.
How do cyclones and anticyclones form?
Cyclones produce thunderstorms that can potentially produce tornadoes. Mid latitude cyclones often produce fronts from their rotation by forcing contrasting air masses together. Thunderstorms often form along these fronts. This is how most tornadoes form. Anticyclones generally tend to suppress thunderstorms ans thus tornadoes rather than produce them.
