Tropical Cyclones In Australia

Location: Tropical cyclones occur in the northern part of Australia, around the periphery, or in the tropics. The areas most affected by tropical cyclones are Queensland and Western Australia, with New South Wales being one of the states rarely affected. The season for tropical cyclones in the southern hemisphere is from November to April.

What is a tropical cyclone: Tropical cyclones are a type of low-pressure systems which generally form in the tropics. They are violent storms, which rotate anti clockwise. Cloud and wind rotates a calm central area, in the tropics (area north or south of the equator) and causes damage to people's properties, death, destruction of recourses, and leaves people severely injured. Tropical cyclones occur when warm air rises from the seas, and condense into the clouds, causing huge amounts of heat to be released. As a result of the mixture of heat and moisture, a collection of thunderstorms are produced, from which a tropical storm can develop. There are various names given to tropical cyclones depending where about on the world you are, what is called a typhoon in the western north Pacific and Asia including Japan is called a hurricane in north and central America, and a cyclone in other areas of the world such as here in Australia.

Impacts of tropical cyclones in its surroundings:

Tropical cyclones affect the social, environmental, and economic part of the world. People who have experienced a natural disaster will never be the same again.

Social: They have also affected people socially by leaving people severely injured or dead. Tropical cyclones have also had an emotional effect on people, leaving them homeless and affected by the devastation and damages around them.

Environmental: Tropical Cyclones affect the world environmentally by causing damage to houses, properties and destruction of resources. They are also very important environment because of the ecosystems. Reefs and the distribution of plants and sand have adapted to the heat produced by the tropical cyclones.

Economic: Tropical cyclones have also affected the economic part of the world, because hundreds of homes are being destroyed each year, it is causing the government millions of dollars to financially rebuild people's lives. It cost about $1467 million for the government to pay each year. Some other natural disasters for example, droughts are non insurable events.

Tropical Cyclone Ingrid

Unrelenting Tropical Cyclone Ingrid caused a great impact on the Australian

coast in March 2005. It was unusual because it is the only cyclone in

recorded history to impact, on the coastline of three different States or Territories. It began as a category 4 cyclone but finally emerged as a category 5 cyclone (the strongest category). Ingrid was a small cyclone in size, but made up for its size with its intensity and power. Some effects of Tropical Cyclone Ingrid included significant rainfall, (eg 445mm in 24 hours at Emma Gorge in the Kimberley). Large sea swells formed by the cyclone in the Coral Sea were also a great effect and 5 people died as a result of it, (they capsized). Other effects included Tree Damage, damage to infrastructure, loss of vegetation, etc.

The communities, however, all received good warning, and much preparation, including the clearing of loose materials around the populated

areas, reducing the final damage toll.
