Impact on the environment
Where cyclones occur
cause
A cyclone is caused when warm air over the water rises and cooler air replaces it. The cooler air warms up and rises. This cycle then causes huge storm clouds to form.These clouds will begin to rotate with the spin of the earth, forming an organized system.If there is enough warm water in the air the cycle will continue and the storm clouds and wind speeds will grow causing a cyclone to form.
What is a cyclone?
Cyclones are very strong spinning storm systems with low pressure centres that can be large in size. A low pressure system is a whirling mass of warm air that can bring stormy weather and strong winds. Cyclones form over warm oceans and cause great damage when they approach land.
Cyclones can be dangerous to animals.Farm animals have been known to be lifted off the ground by the wind's force.Or injured by moving debris.Cyclones can also damage ecosystems including the ocean, where coral reefs can take years to recover (see image of damaged reef after category 5 Cyclone Hamish.

World Map
Australian map
Cyclones occur in tropical places such as Australia, the Philippines, the Gulf of Mexico, Florida, and New Orleans. On the world map the orange parts are the countries where the cyclones occur. All of the countries are close to the equator, which indicates the warmest parts of the planet. On the Australian map (far right) the green strokes represent the wind formation and the pressure systems. The two recent cyclones Marsha and Lam can be seen on this map.
Help after a cyclone
diagram
Cyclones can have an enormous impact on
people.They can rip roofs off houses and flatten
buildings, leaving people without shelter,food,
clothing and running water. Sewerage pipes can
break causing pollution to run everywhere. This
can cause disease making people sick and they only have limited access to medical help because hospitals have been destroyed.
