Geographical processes associated with tropical cyclones
Tropical cyclones form over warm oceans (above 26.5˚ C) as low pressure systems and gradually build up intensity. They have clockwise wind circulations and produce gale force winds. These winds can extend hundreds of kilometers from the cyclone center
Tropical cyclones can persist for many days and many follow quite erratic pats. they usually break up or dissipate over land or cooler oceans the circular eye or center of a tropical cyclone is an area carctorise by light winds and often by clear sky. The diameter of the eye is usually aprrox 40 km but can rang from 10 to 100km.the eye is surrounded by a dense ring of cloud about 16 killomiters high,know as the eye wall,witchmarks the belt of the stongest winds and heviest rainfall. The severty ofa tropical cyclone is described in terms of categories ranging from 1 to 5 realated to the the zone of maximum winds
Natural disasters and hazards
A hazard is an event that is a potential source of harm to human life/health/and possessions
Natural hazards are dangerous occurrences in the physical environment event such as a river flooding and earth quakes occur naturally but are only considered hazards in relation to human occupation of a particular place
It’s only a hazard if human life is affected
A natural hazard becomes a natural disaster when damage to people property or society is sufficient to cause a long recovery and rehabilitation process
The four major hazards that affect are
1. drought
2. bush fires
3. tropical cyclones and storms
4. floods
