The directions of the Westerlies are opposite to trade winds and that is why they are also called antitrade winds. Westerlies blow in the middle latitudes between 30 and 60 degrees latitude, and originate from the high pressure area in the horse latitudes towards the poles.
What is the difference between westerlies and Tradewinds?
The Westerlies are winds from the west and southwest predominant from roughly 30° to 55°N, with a symmetrical belt of westerlies to northwesterlies from 30° to 55° S. the Trade Winds are the much more paradigmatic belt, with more consistent and commonly stronger winds than those of the Westerlies.
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth’s equatorial region.
What are the westerlies winds?
Westerlies are prevailing winds that blow from the west at midlatitudes. They are fed by polar easterlies and winds from the high-pressure horse latitudes, which sandwich them on either side.
Answer: Trade winds are the breeze that streams towards the equator from the north-east in the Northern Hemisphere or from the south-east in the Southern Hemisphere. These are otherwise tropical easterlies and are known for their consistency in force and heading.
What is westerly and easterly winds?
Easterly winds blow from the east, while westerly winds blow from the west.
Why are easterlies called trade winds?
The trade winds were named by the crews of sailing ships that depended on the winds during westward ocean crossings.
What are the three types of trade winds?
What direction do westerlies move?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
What causes the westerly winds?
What Causes Westerlies? Westerlies are formed due to high-pressure systems within the mid-latitudes. The hot air near the equator rises, and the cold air from surrounding areas replaces the hot air. The air begins to circulate, which is how the westerlies are formed.
What is the main role of the westerlies?
The Westerlies play an important role in carrying the warm, equatorial waters and winds to the western coasts of continents, especially in the southern hemisphere because of its vast oceanic expanse.
Are westerly winds cold?
A true, classic north westerly wind brings polar maritime air towards the UK. This is an air mass that has polar origins, yet has travelled over the mid-Atlantic. So it is cold, but has been warmed from below by the relatively warm Atlantic Ocean.
What is the definition for westerlies?
/ (ˈwɛstəlɪz) / Save This Word! pl n. meteorol the prevailing winds blowing from the west on the poleward sides of the horse latitudes, often bringing depressions and anticyclones.
What are westerlies winds Class 7?
Westerlies are also known as Shrieking Sixties, Furious Fifties and Roaring Forties. These winds blow from the subtropical high-pressure belts towards sub-polar low-pressure belts. The westerlies of the Southern hemisphere are stronger and constant as compared to that of the Northern hemisphere.
What are westerlies Class 7?
The Westerlies: The westerlies blow from the sub-tropical high pressure belt to the sub-polar low pressure belts. They are called the westerlies as they blow constantly from the west.
What are trade winds class 11 physics?
What Are Trade Winds? Trade winds can be defined as the wind that flows towards the equator from the north-east in the Northern Hemisphere or from the south-east in the Southern Hemisphere. These are also known as tropical easterlies and are known for their consistency in force and direction.
Are westerlies cold or warm?
The winter westerlies, often from the southwest, bring in warm tropical air; in summer, by contrast, they veer to the northwest and bring in cooler Arctic or subarctic air. In Mediterranean Europe the rain-bearing westerlies chiefly affect the western areas, but only in winter.
What kind of wind is the southeast trade winds?
trade wind, persistent wind that blows westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone (ITCZ).
Are monsoon winds trade winds?
The easterly winds that blow in the tropics near the equator are called trade winds. a. Winds that blow from the Indian Ocean and South Asia and which carry moisture are called monsoon winds.
What are variable westerlies?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.
What are the 4 types of local winds?
The local difference in temperature and pressure causes local winds. It is of four types: hot, cold, convectional and slope.
Is an example of local wind?
Examples of local winds include sea breezes, which blow from the sea to the land and keep coastal temperatures more mild, and land breezes, which blow from the land toward the sea, usually at night.
How do prevailing westerly winds affect North America?
How do prevailing westerlies affect North America? These prevailing winds blow from the west to the east, and steer extra-tropical cyclones in this general direction. … The westerlies explain why coastal North America tends to be wet, especially from Northern Washington to Alaska, during the winter.
Why do the trade winds and the westerlies curve?
Because Earth rotates as the air is moving, the winds in the Northern Hemisphere curve to the right and air in the Southern Hemisphere curves to the left. This phenomenon is called the Coriolis Effect and it’s why the trade winds blow toward the west in both the Northern Hemisphere and Southern Hemisphere.
Are westerly winds from the west?
The name of these unique winds comes from the direction of their origin; the westerlies run west to east while other winds run east to west.
Are westerly winds cold in Australia?
To the south of the anticyclonic system, westerly winds and a procession of cold fronts associated with the “roaring forties” (windy zone between latitudes 40° and 50° S) bring cool, cloudy weather and rain and westerly gales along the southern coast.
What are westerly winds Mcq?
What are westerly winds? 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.
What is equatorial westerly wind?
Quick Reference. The westerly winds that sometimes develop within the equatorial trough when the Intertropical Convergence Zone is well north or south of the Equator. The north-easterly or south-easterly trade winds cross the Equator and, because of the reversal of the Coriolis effect, acquire a westerly component.
What is meant by local winds?
Winds which are generated over a comparatively small area by local terrain and weather. They differ from those which would be appropriate to the general pressure pattern.
What are local winds Name any two local winds?
The main types of local winds are sea breezes and land breezes, Anabatic and katabatic winds, and Foehn winds.
What Are winds explain different types of winds Class 11?
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.
What are local winds 7?
What are local winds 7? Local Winds: Local winds are unique to certain well-defined areas. They blow over a small area from a small area from a particular period. They affect only the local weather conditions of that place.
What is wind explain seasonal and local winds?
Type of Wind ” Seasonal Wind The winds that change their direction with onsets of different seasons. These are hence called as Seasonal Winds. A monsoon is a type of seasonal wind in low-latitude climates that seasonally changes direction between winter and summer. Monsoon is prevalent in India.
What is wind How are winds classified Class 7?
Wind. Moving air is called Wind. Since air is a mixture of gases, wind is the flow of gases on a large scale. Winds are caused by heating difference between different parts of the world and the movement of the earth.
Where are the trade winds?
The trade winds can be found about 30 degrees north and south of the equator. Right at the equator there is almost no wind at all”an area sometimes called the doldrums.
What are trade winds Mcq?
Explanation: Trade winds are extremely steady winds blowing from sub-tropical high pressure areas to equatorial low pressure areas. They maintain a constant direction throughout their course.
Is a westerly wind cold NZ?
Westerly winds are the most common. They carry wet weather to areas upwind of the main mountain chains, and dry, warm weather along the east coasts. Westerly airstreams often extend for thousands of kilometres upstream of New Zealand.

What are North East trade winds?
North-east trade winds prevail during the winter season in India. These are the winds that blow from land to the sea. This is the reason why winters in India are dry. A part of north-east winds blows over the Bay of Bengal which bring showers to Coromandel Coast.
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.
