How is a cyclone formed
A cyclone is formed out at sea usually when the temperature of the sea is over 26 degrees Celsius after which the warm water evaporates and form clouds. If there is low air pressure where the clouds are formed the warm air will start to rise. This causes the surrounding air to fill the space causing it to rotate. More clouds will form and the cyclone will grow bigger. When the cyclone reaches land it will begin to weaken and fade due to the lack of moisture. The cyclone must produce gale winds of at least 63km/h for it to be considered a cyclone. If the sustained winds reach 118km/h it is considered to be a severe tropical cyclone.
