What Are Planetary Winds

What Are Planetary Winds?

Any wind system of the earth’s atmosphere which owes its existence and direction to solar radiation and to the rotation of the earth. …

What are planetary winds answer?

Complete answer:

Planetary winds are defined as those winds which are distributed in the lower portion of the atmosphere and blow regularly throughout the year in limited areas of latitudinal belts in the north-east and south-east direction or from high pressure to low pressure regions.

What are examples of planetary winds?

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.

What are planetary winds for Class 7?

Permanent winds are also known as prevailing winds or planetary winds. They are called permanent winds because they blow throughout the year constantly in the same direction. They are of three types- trade winds westerlies and polar winds.

How are planetary winds formed?

When a difference in atmospheric pressure exists air moves from the higher to the lower pressure area resulting in winds of various speeds. On a rotating planet air will also be deflected by the Coriolis effect except exactly on the equator.

Why are planetary winds also called permanent winds Class 7?

Planetary winds constantly blow in the same direction all around the world throughout the year from one latitude to the other. They are also called prevailing or permanent winds because they blow in the same direction constantly throughout the year.

What are planetary winds describe the main planetary winds on Earth?

The main features of planetary wind are polar winds westerlies and trade winds. Explanation: Planetary wind refers to those wind that blows from one latitude to another and which are controlled by the factors such as changes in the temperature and pressure Coriolis effect.

What are planetary winds 6?

Planetary winds are also known as permanent winds. The trade winds the Easterlies and the Westerlies are known as planetary or permanent winds as they continuously blow throughout the year. These winds always blow in a particular direction.

Is Chinook a local wind?

Chinook is the warm and dry local wind blowing on the leeward side or eastern side of Rockies (Prairies). Chinook is more common in winter and early spring from Colorado to British Columbia in Canada. The winds after descending through eastern slopes of the Rockies have warmed adiabatically.

What are the different types of planetary winds and periodic winds explain briefly?

There are two types of planetary winds i.e. the trade winds and the westerly winds. On the other hand Sometimes wind change their direction with the change of season or time. Such winds are called periodic winds. Monsoon land and sea breezes and mountain and valley breezes come under the category of periodic winds.

What are planetary or prevailing winds Mcq?

What are planetary or prevailing winds? Explanation: Planetary winds are winds that blow from one latitude to another throughout the year due to latitudinal differences in air pressure. They cover large areas of earth. 7.

What is wind in geography?

Wind is the movement of air caused by the uneven heating of the Earth by the sun and the Earth’s own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes. … Landforms processes and impacts of wind are called Aeolian landforms processes and impacts.

What are the effects of planetary winds?

Planetary Winds affect climate because they cause the land to cool down. 2.) They also cause the moisture in the air to condense and then form clouds which results in precipitation.

What is planetary winds and pressure belts?

Complete answer: > Pressure belts are distinct identifiable zones of homogenous pressure on earth. Equatorial low subtropical highs sub polar lows and polar highs are the types of pressure belt on earth. Planetary winds are the winds in the lower atmosphere that are being controlled by these pressure belts.

How local winds are different from planetary winds?

Answer: Planetary winds are winds that blow on a global scale whereas local winds are mainly located on a smaller area in a given region. Planetary winds flow throughout the year without any seasonal changes whereas local winds are based on season and are shorter duration.

What are planetary wind belts?

The global wind belts are the three wind belts or wind patterns that cover the planet: the tropical easterlies (or the trade winds) are found near the equator the polar easterlies are found at the north and south poles and the prevailing westerlies are found between the two.

What are the 3 types of winds?

The three chief types of winds are Trade winds Westerlies and polar winds.

What are called permanent winds?

Permanent winds- The trade winds westerlies and easterlies are the permanent winds. These blow constantly throughout the year in a particular direction. 2. Seasonal winds – These winds change their direction in different seasons.

Which Wind is also known as permanent wind?

The wind blowing from sub-tropical high-pressure belts towards the equatorial low-pressure belt is known as trade winds. They are strongest during winter and weakest during summer. The trade winds blow with great regularity and steadiness. That is why trade winds are known as permanent winds.

What are planetary winds Shaalaa com?

Planetary winds are also called permanent or prevailing winds as they blow the year-round in the same areas.

What are the 4 types of winds?

Types of Wind – Planetary Trade Westerlies Periodic & Local Winds.

Why is Lethbridge so windy?

With average winds of 18.3 km/h and a record max gust of 171 km/h the winds in Lethbridge tend to come from the west or southwest largely due to its location on the prairie within blowing distance of Rocky Mountain chinooks.

Why is Calgary so windy?

Calgary has a windy climate which it owes to its prairie location – there are few natural barriers to the wind. At times the wind in Calgary takes the form of a Chinook a hot dry Foehn type wind that blasts down from the Rockies. … When the Chinook blows it can cause rapid thawing of snow to slush.

What is the hot wind called?

Sirocco. A sirocco is a hot desert wind that blows northward from the Sahara toward the Mediterranean coast of Europe. More broadly it is used for any kind of hot oppressive wind. … The sirocco was gently blowing the air was heavy she was tired she looked a little pale.

What is variable wind?

Variable winds are those winds which blow in a small area and are related to the pressure systems. They are known as variable winds as they do not blow in a definite direction and their speed and velocity varies with the pressure system. Two main kinds of variable winds are cyclones and anti-cyclones.

What are planetary or prevailing winds?

Planetary Winds Definition – The winds that flow throughout the year from one latitude to another latitude because of latitudinal differences in the air pressure are called planetary winds. They are also called prevailing winds. Planetary winds blow from a single direction over a specific area over the earth.

What causes the curved paths of the planetary winds *?

The Coriolis effect is the apparent curvature of global winds ocean currents and everything else that moves freely across the Earth’s surface. The curvature is due to the rotation of the Earth on its axis. The effect was discovered by the nineteenth century French engineer Gaspard C. Coriolis.

What are westerly winds Mcq?

Explanation: Westerly winds are winds blowing from sub-tropical high pressure areas to sub-polar low pressure areas. The direction of flow is from west to east between 30 and 60 degrees latitude. … Explanation: Monsoons land and sea breeze mountain and valley breeze are examples of periodic winds.

What are planetary winds Upsc?

Planetary Winds

These winds are in the form of large air masses which are being formed due to the earth’s rotation along with the shape of the earth and the sun’s heating power. Those winds which blow from one latitude to another due to the latitudinal difference in air pressure are known as Planetary Winds.
