Question

What are the different types of wind? Explain each of them?​

Answer 1

Answer:

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.

Answer 2

Explanation:

Types of Wind

Wind blowing above the earth surface may be classified into five major types:

1. Planetary winds

2.Trade winds

3.The westerlies

4.Periodic winds:

Monsoon winds

Land breeze

Sea breeze

Mountain and valley breeze

Local winds

Planetary Winds

Planetary winds comprise winds distributed throughout the lower atmosphere. The winds regularly blow throughout the year confined within latitudinal belts, mainly in north-east and south-east directions or from high-pressure polar-regions to low-pressure regions.

Trade Winds

These winds are also known as tropical easterlies and blow from the right in Northern hemisphere and to the left in the Southern hemisphere due to Coriolis effect and Ferrel’s law. They start blowing from the sub-tropical high-pressure areas towards the equatorial low-pressure belt. In the Northern hemisphere, they blow as northeastern trades, and in the Southern hemisphere they blow as southeastern trades.

Periodic Winds

These winds change their direction periodically as there is a change in the seasons. Following are the types of periodic winds:

Monsoon winds: The temperature difference created by the Indian Ocean, Arabian Sea, Bay of Bengal and Himalayan wall forms the basis of monsoon in the Indian subcontinent.

Land breeze: These winds blow from land to sea, carrying no moisture but dry and warm.

Sea breeze: These winds blow from sea to land, carrying some moisture.

Mountain and valley breeze: Valley breeze is the hot air blowing from the valley which flows up to the slopes of mountain slopes. In contrast, mountain breeze is the valley breeze that is the cold air from the mountain flow towards the valley.

Local winds

The local winds include the sea and the land breeze created due to the pressure difference between the air over the sea and the land regions. Loo is the local winds that blow in the northern part of India.
