How do you explain cyclones to children?
A cyclone is a powerful spinning storm that contains strong winds and rain that swirl around a calm eye, or center. Cyclones form as warm, moist air rises over the waters of the South Pacific and Indian Ocean forming clouds and wind. When the wind speeds exceed 74 miles per hour, the storm becomes a cyclone.
What are cyclones PPT?
CYCLONES. Cyclone refers to any spinning storm that rotates around a low-pressure centre. Closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce a heavy rain.
What are tropical cyclones called in India?
The same kinds of storms in the Southern Hemisphere are easier to keep straight. In the southern Indian Ocean or the South Pacific, they are called tropical cyclones or severe tropical cyclones. In the Bay of Bengal or Arabian Sea, both in the northern Indian Ocean, they are simply called cyclones.
What is tropical cyclone in simple words?
Tropical cyclones, also known as typhoons or hurricanes, are among the most destructive weather phenomena. They are intense circular storms that originate over warm tropical oceans, and have maximum sustained wind speeds exceeding 119 kilometres per hour and heavy rains.
What causes tropical cyclones?
Tropical cyclones are low pressure systems that form over warm tropical waters. They typically form when the sea-surface temperature is above 26.5°C. Tropical cyclones can continue for many days, even weeks, and may follow quite erratic paths. A cyclone will dissipate once it moves over land or over cooler oceans.
What are the features of a tropical cyclone?
Characteristic features of tropical cyclones are the eye, a central region of clear skies, warm temperatures, and low atmospheric pressure; the eyewall, the most dangerous and destructive part where winds are strongest and rainfall is heaviest; and rainbands, secondary cells that spiral into the center of the storm.
What causes cyclones in India?
Cyclones are caused by atmospheric disturbances around a low-pressure area distinguished by swift and often destructive air circulation. Cyclones are usually accompanied by violent storms and bad weather.
What are the characteristics of tropical cyclone?
A tropical cyclone brings very violent winds, torrential rain, high waves and, in some cases, very destructive storm surges and coastal flooding. The winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
What is the effects of tropical cyclone?
The effects of tropical cyclones include heavy rain, strong wind, large storm surges near landfall, and tornadoes. The destruction from a tropical cyclone, such as a hurricane or tropical storm, depends mainly on its intensity, its size, and its location.
