When a cyclone hits it leaves a path of destruction. Cyclones have a bad history in Australia. Like in 2006 when cyclone Larry hit in Cains and the entire banana trees were destroyed.

Cyclones

Strong tropical storms happen when heavy winds blow into an area of a low pressure being to spin very fast. They form over warm seas and build up speed until they get to land. Where there is no more moist air to feed them some storms bring fierce rain.

This part is called the, eye, as the eye of the storm pass over. There is a pause in the scary rains and wind.

How does a cyclone form


A cyclone is a low pressure system. A cyclone forms over the ocean were the sea is warmer then 26.5*c and were a low pressure system.


A cyclone forms in the tropical regions only.

A cyclone cannot survive to travel across Australia.

A cyclone can bring lot of rain clouds like cumulonimbus clouds.

The water has to be 26.5*c and more for a cyclone to form in a low pressure system.

When a tropical cyclone reaches 17 meters per second called a tropical storm.

A cyclone is a low pressure system that has formed of 26*c while it is over warm water it will build up speed and froce until it hits land then it slowley disnergrates
