What is a cyclone Class 6?
A cyclone is formed by a very low-pressure system with very high-speed winds revolving around it. The low-pressure region is called the eye of the cyclone.
What is a cyclone simple definition?
Definition of cyclone (Entry 1 of 2) 1a : a storm or system of winds that rotates about a center of low atmospheric pressure, advances at a speed of 20 to 30 miles (about 30 to 50 kilometers) an hour, and often brings heavy rain. b : tornado.
What is cyclone by Wikipedia?
In meteorology, a cyclone (/ˈsaɪ. kloʊn/) is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone).
What is a cyclone Class 7?
A cyclone is a weather condition consisting of a system of high-speed winds revolving around a central area of very low pressure. Cyclones develop over tropical seas. It is a violent storm with a wind speed of 150-250 km/h. It is accompanied by strong winds and heavy rains.
What is a cyclone Class 8?
A cyclone is a region of low atmospheric pressure. It occurs as a swirling atmospheric disturbance, accompanied by powerful cyclonic winds blowing in a clockwise direction in the Northern Hemisphere and in an anti-clock wise direction in the Southern hemisphere. The winds travel usually at speeds of over 300 km/h.
What is a cyclone Class 9?
Cyclones is a small low pressure system winds blowing from the surrounding high pressure areas.It rises causing swirls in the atmosphere. It then cools off to form clouds.
What causes a cyclone?
Cyclone is system of winds rotating inwards at a high speed with the area of low pressure in the middle. Tropical cyclones are formed only over warm ocean waters near the equator. When warm, moist air over the ocean rises upward from near the surface, a cyclone is formed.
What are types of cyclones?
There are 4 types of cyclones and they are:
- Tropical cyclone.
- Polar cyclone.
- Mesocyclone.
- Extratropical cyclone.
How is cyclone formed?
The cyclone is formed when the warm, moist air rises upward over the ocean. As this air moves up, there is a formation of a low-pressure area below. Now the low-pressure area is filled with the high-pressure air from the surroundings. Again, the next batch of cool air gets warm and moist over the ocean moving upward.
How are cyclones named?
The India Meteorological Department is one of the six regional centres. It gives a name to a cyclone that forms over the northern Indian Ocean and reaches a maximum sustained surface wind speed of 62 km/h. The name is taken from a list which contains suggestions categorised alphabetically and country-wise.
What are the different types of cyclones?
