Cyclone vs Anticyclone


Cyclone vs Anticyclone
Cyclones and anticyclones are generated when areas of high and low air pressure collide. These are created by differences in temperature and humidity.

Air temperature affects the molecules’ kinetic energy. The higher the temperature, the more the molecules move and collide. Humidity, on the other hand, affects the air itself. The atmosphere’s main constituents – diatomic oxygen and nitrogen – are heavy compared to water vapour. The water in humid air replaces some of the heavier molecules, making it lighter than dry air, and therefore of a lower pressure.

An anticyclone is a region of high atmospheric pressure. The air descends through the system, spreading out sideways as it makes contact with the ground. The compressed air causes a rise in temperature – hence why anticyclones are associated with summer weather and dry winter days.
In contrast, a cyclone is centred around a region of low pressure. Inward spinning winds draw air upwards into the system – as it rises, water vapour cools and condenses, resulting in cloudy weather and storms.
