Question

What is a cyclone? Where do they occur?how do they impact on humans and the environment?

Answer 1

Answer:

The Hazard

Tropical cyclones are among the most destructive natural phenomena. The impact from cyclones extends over a wide area, with strong winds and heavy rains. However, the greatest damage to life and property is not from the wind, but from secondary events such as storm surges, flooding, landslides and tornadoes.

Factors of Vulnerability

Man made factors:

Settlement located in low lying coastal areas (direct impact);

Poor building design, or construction;

Insufficient lead time for warning and evacuation;

Non compliance with evacuation procedures;

Inadequate shelter.

Main causes of Morbidity and Mortality

Direct Impact

Injuries, trauma, and asphyxiation due to entrapment are observed and result from building collapse and wind-strewn debris. Electrocution or drowning happen while securing property such as television antennas or boats.

Short and long term mental health effects are observed.

Indirect Impact

The impact of tropical cyclones on the transmission of communicable diseases is limited. Outbreaks of communicable diseases are rarely observed. Nonetheless, the risk for water borne disease and vector transmitted disease can be exacerbated: human exposure to disease vectors can be increased due to changes in the physical environment.

The impact on the health infrastructures and all lifeline systems is massive and can result in food shortages and interruption of basic public health services (water, etc).

In case of floods and sea surges, risks of drowning and water borne and vector borne disease increase.

Answer 2

In meteorology, a cyclone refers to any low pressure area with winds spiralling inwards. Cyclones rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. Cyclone is the general term for a variety of low pressure system types, such as tropical cyclones, extra tropical cyclones and tornadoes.
