Question

write three layer of wind. explain about each with example.​

Answer 1

Answer:

Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the Sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in the Solar System occur on Neptune and Saturn. Winds have various aspects: velocity (wind speed); the density of the gas involved; energy content or wind energy. The wind is also an important means of transportation for seeds and small birds; with time things can travel thousands of miles in the wind.

Explanation:

As simple as that.

Answer 2

Answer:

TYPES OF WINDS - DEFINITION

The various types of winds are:

(1) Permanent or Planetary winds

(2) Periodic winds

(3) Local winds

(4) Cyclones and Anticyclones

LOCAL WINDS - DEFINITION

The local winds are truly local. They occur over a much smaller land scale and are related to the topographical features of that particular place. They blow for a short period and are caused due to the particular shape of the land or nearness to a body of water that generates a specific movement of air.

The examples of local winds in India: Kalbaisakhi (West Bengal), Loo (North India).

PLANETARY WINDS - DEFINITION

Planetary winds, prevailing winds or permanent winds are those which blow continuously in the same belt all through the year. They blow from high pressure belt to low pressure belts. There are three main types of planetary winds - the trade winds, the westerlies and the easterlies. These winds are named according to the direction from which they blow.

PERIODIC WINDS - DEFINITION

These are the winds blowing at a much smaller scale in comparison to the planetary winds.

The planetary winds include:

(1) Land and Sea Breezes

(2) Monsoons.

ANTI-TRADE OR WESTERLIES - DEFINITION

These are variable winds and not as constant in strength and direction as the trade winds. The westerly wind belt is characterised by frequent cyclones and anti-cyclones. They blow from the subtropical high pressures belt 300

north and south of the Equator to the sub polar low pressure belt. In the Northern Hemisphere, they blow from SW to NE. In the Southern Hemisphere, the direction is NW to SE.

DEFLECTION OF WIND - DEFINITION

The rotation of the Earth causes a force known as the Coriolis Force due to which they deflect more than a slow wind. The change in the wind direction as a result of the coriolis force is stated in Ferrel's Law. This law states that any horizontally moving fluid or object would deflect to the right in the Northern Hemisphere and to its left in the Southern Hemisphere due to the Earth's rotation.
