Science / Wind, Storms and Cyclones

Science / Wind, Storms and Cyclones

Cyclone

Air exerts pressure on its surroundings. Air expands when heated and contracts when cooled. When the air is heated it becomes lighter and it rises. This causes the air pressure to reduce.

The cooler air in the surrounding areas moves in to balance the pressure. This movement of air is called the wind.

Wind movements are caused by uneven heating of earth. The water vapor in the air causes the rain. High speed winds with severe rain are called cyclones.
