What are the factors that contribute to the development of cyclones Class 7?

What are the factors that contribute to the development of cyclones?

Factors like wind speed, wind direction, temperature and humidity contribute to the development of cyclones.

What are the causes of cyclones Class 7?

A cyclone is formed when warm, moist air near the ocean’s surface rises upward. When air rises away from the ocean’s surface, it generates a low-pressure zone beneath it. It causes air from higher-pressure places to travel towards the low-pressure area, warming the air and causing it to climb above.

What are the different factors that contribute to the development of cyclones explain how the thunderstorm becomes a cyclone?

Thunderstorm becomes a Cyclone

When water vapour changes back to liquid form as raindrops, this heat is released to the atmosphere. The heat released to the atmosphere warms the air around. The air tends to rise and causes a drop in pressure. More air rushes to the centre of the storm.

Which one is not contribute to the development of cyclone?

The Coriolis force that compels the surface winds to spiral towards the low-pressure system. As Coriolis force is negligible in the equatorial belt between latitudes 5 degrees north and 5 degrees south, cyclonic systems do not develop in this region.

What are the basic requirements for the formation of a cyclone?

The basic requirements for the formation of cyclone are as mentioned:

  • Large and continuous supply of warm and moist air.
  • Strong Coriolis force.
  • Unstable condition through the troposphere that creates local disturbances around which a cyclone develops.
  • Absence of strong vertical wind wedge.

What are the causes of wind generation in nature Class 7?

The Wind is caused by air moving from areas of high pressure to areas of low pressure. It is produced by the uneven heating of the earth’s surface by the Sun. Some parts of the earth are warm and some, cold. Warm air, which weighs less than cold air, rises.

What is cyclone Class 7 BYJU’s?

Cyclone is defined as the mass of air that rotates around the centre of low pressure on a large scale. Cyclone is characterized by inward spiralling winds, rotating clockwise (Southern Hemisphere) or anticlockwise (Northern Hemisphere).

How does a cyclone create thunderstorms?

The air moves from surrounding high-pressure areas to the central low-pressure area. This cycle is repeated. The chain of events leads to the formation of very low-pressure system surrounded by with very high-speed winds. This weather condition is a cyclone.

How it thunderstorm become a cyclone?

Explanation: The water requires heat when it changes from liquid to Vapour state. The water gives back heat when vapour condenses into liquid and a very low pressure area is created. This is how a thunderstorm becomes a cyclone.

Where do thunderstorms develop?

Thunderstorms can form and develop in any geographic location but most frequently within the mid-latitude, where warm, moist air from tropical latitudes collides with cooler air from polar latitudes. Thunderstorms are responsible for the development and formation of many severe weather phenomena.
