Cyclones


Cyclones are huge revolving storms caused by winds blowing around a central area. Cyclones begin in tropical regions like Australia and Asia and many other pacific islands. Australia for example has about five or six cyclones every year during the summer. To occur a cyclone the sea must have a temperature of at least 26º C.
