Where do northeast and southeast trade winds meet?

The northeast and southeast trade winds meet there; this meeting causes air uplift and often produces clusters of convective thunderstorms. They occur along the Equator in the Indian and western Pacific oceans and slightly north of the Equator off the African and Central American west coasts.

Where are trade winds located?

The trade winds or easterlyies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase.

Which islands face into the northern trade winds?

While the flat islands Lanzarote and Fuerteventura have a uniform climate in practically the whole of the island and also a uniform and scarce vegetation, there are different zones in the mountaneous islands: in the north/east where the trade winds accumulate there are much more rinfalls than in the south/west.

What are north eastern trade winds?

The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by captains of sailing ships to cross the world's oceans for centuries.

Where are the northeast trade winds?

In the Northern Hemisphere they begin as north-northeast winds at about latitude 30°N in January and latitude 35°N in July, gradually veering to northeast and east-northeast as they approach the equator.

What are north-east trade winds Class 9?

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.

What are trade winds?

The trade winds are air currents closer to Earth's surface that blow from east to west near the equator. The trade winds have been used by sailors for centuries. Sailors traveling from Europe or Africa used the trade winds to travel to North or South America.

Why are they called trade winds?

East to West, actually. Trade Winds, so named because if you had a ship full of goods to sell or trade and no way to get it to the place you wanted to sell or trade it other than your sailing vessel, a reliable and predictable wind that always blew in the same places in the same direction would be pretty nifty.

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.

Why are northeast trade winds dry?

Answer. Answer: These winds generally travel towards the southern part of the continent. So by the time they reach the southern zenith they become anhydrous and already run out of the moisture due to which they are incapable of drenching areas of the south and are hence referred to as dry.

What are south-east trade winds?

South-east trade winds are drawn to the low-pressure area. After crossing the equator, due to Coriolis force, these trade winds veer right towards low-pressure areas in India and begin blowing in the southwestern direction. The southwest monsoon follows these trade winds into India's peninsular region.

What is trade wind?

The Short Answer: The trade winds are winds that reliably blow east to west just north and south of the equator. The winds help ships travel west, and they can also steer storms such as hurricanes, too. When you’re outside, you might notice that one day the wind blows one direction and the next day, wind is blowing a different direction.

Why do trade winds blow toward the west?

The trade winds blow toward the west partly because of how Earth rotates on its axis. The trade winds begin as warm, moist air from the equator rises in the atmosphere and cooler air closer to the poles sinks. The trade winds are created by a cycle of warm, moist air rising near the equator.

What is the area of wind at the equator called?

The area of almost no wind at the equator is called the doldrums. Credit: NASA/JPL-Caltech.

What happens when wind blows in one direction?

When you’re outside, you might notice that one day the wind blows one direction and the next day, wind is blowing a different direction. That’s a pretty common occurrence. However, many winds on Earth are quite predictable. For example, high in the atmosphere, the jet streams typically blow across Earth from west to east.

How are trade winds created?

The trade winds are created by a cycle of warm, moist air rising near the equator. The air eventually cools and sinks a bit further north in the tropics. This phenomenon is called the Hadley cell. Credit: NASA/JPL-Caltech.

How did sailors use trade winds?

Just like airplanes can use the wind boost from the jet stream to shorten a journey flying east, sailors can use the trade winds to shorten a sea journey when sailing west.

Where do jet streams blow?

For example, high in the atmosphere, the jet streams typically blow across Earth from west to east. The trade winds are air currents closer to Earth’s surface that blow from east to west near the equator. The trade winds blow from east to west near the equator. Credit: NASA/JPL-Caltech.

What was the trade wind?

Early commerce to the Americas relied on the trade winds—the prevailing easterly winds that circle the Earth near the equator.

How did the trade winds help sailors?

Known to sailors around the world, the trade winds and associated ocean currents helped early sailing ships from European and African ports make their journeys to the Americas. Likewise, the trade winds also drive sailing vessels from the Americas toward Asia.

What is the belt around the Earth's midsection called?

This 10-degree belt around Earth's midsection is called the Inter-Tropical Convergence Zone, more commonly known as the doldrums .

What are the trade winds in the Northern Hemisphere?

Because winds are named for the direction from which the wind is blowing, these winds are called the northeasterly trade winds in the Northern Hemisphere and the southeasterly trade winds in the Southern Hemisphere. The trade winds of both hemispheres meet at the Doldrums.

When does the trade wind move?

During mid-summer in the Northern Hemisphere (Ju ly), the westward-moving trade winds south of the northward-moving subtropical ridge expand northwestward from the Caribbean sea into southeastern North America (Florida and Gulf Coast).

What are the prevailing winds that flow in the equatorial region?

Permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The westerlies (blue arrows) and trade winds (yellow and brown arrows) The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in ...

What did the Portuguese do to the trade winds?

The Portuguese recognized the importance of the trade winds (then the Volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic ocean as early as the 15th century. From West Africa, the Portuguese had to sail away from continental Africa, that is, to west and northwest.

How tall are trade wind clouds?

Clouds which form above regions within trade wind regimes are typically composed of cumulus which extend no more than 4 kilometres (13,000 ft) in height, and are capped from being taller by the trade wind inversion.

Where do tropical storms make landfall?

In meteorology, they act as the steering flow for tropical storms that form over the Atlantic, Pacific, and southern Indian oceans and make landfall in North America, Southeast Asia, and Madagascar and East Africa.

When is the windy season in South America?

As an example, the windy season in the Guianas, which lie at low latitudes in South America, occurs between January and April. When the phase of the Arctic oscillation (AO) is warm, trade winds are stronger within the tropics. The cold phase of the AO leads to weaker trade winds.

What is trade wind?

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. These winds are formed when the hot air rises and hits ...

How are trade winds formed?

These winds are formed when the hot air rises and hits the equator where it is pulled towards the poles making them chilled. These winds are used by the sailors. Christopher Columbus discovered America with the help of trade winds.

What are the different types of wind?

Based on the above parameters, wind can be classified into different types: 1 Planetary winds: These winds are also known as prevailing winds and are caused due to the difference in air pressure from one latitude to another latitude. 2 Trade winds: These winds are mainly caused due to the Coriolis effect and Ferrel’s law. They blow as north-eastern trades in Northern Hemisphere and as south-eastern trades in Southern Hemisphere. 3 The westerlies: These winds are developed between 40° and 65°S latitudes and these latitudes are known as the Roaring Forties, Furious Fifties and Shrieking Sixties. 4 Periodic winds: These winds are dependent on seasons and change their direction accordingly like monsoons. 5 Local winds: These are caused due to local differences in temperature and pressure and classified as hot, cold, conventional and slope.

What are the two main causes of the prevailing winds?

Trade winds: These winds are mainly caused due to the Coriolis effect and Ferrel’s law.

What are periodic winds?

Periodic winds: These winds are dependent on seasons and change their direction accordingly like monsoons. Local winds: These are caused due to local differences in temperature and pressure and classified as hot, cold, conventional and slope.

Which hemisphere is the north west?

In the Northern Hemisphere, these are predominantly from the south-west and in the Southern Hemisphere, they are from the north-west. The weather patterns in the United States and Canada are due to westerlies.

What hemisphere do westerlies blow?

They blow as north-eastern trades in Northern Hemisphere and as south -eastern trades in Southern Hemisphere. The westerlies: These winds are developed between 40° and 65°S latitudes and these latitudes are known as the Roaring Forties, Furious Fifties and Shrieking Sixties.
