In what two ways are the north-east trade winds useful?

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.

What are 2 types of trade winds?

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.

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.

What are the main features of north easterly winds?

1. They blow predominantly from the northeast in he northern hemisphere to the southeast in the southern hemishere2. They are alwas prevalent in the low pressure belts across the equatorial zones. 3.It is created when a low pressure belt exists over the equator.

What are trade winds Class 7?

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.

Why are trade winds 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 north easterly winds Class 9?

North easterly winds blow from North East. They are also known as trade winds. trade winds are those wind that flows towards the equator from the north-east in the Northern Hemisphere or from the south-east in the Southern Hemisphere.

What are South East trade winds?

n. (Physical Geography) a wind blowing obliquely towards the equator either from the northeast in the N hemisphere or the southeast in the S hemisphere, approximately between latitudes 30° N and S, forming part of the planetary wind system.

Why is it called North East trade winds?

Because the Earth is rotating, they are deflected. In the northern hemisphere, they blow from the northeast and are called the northeast trade winds. Thus, there is a continuous circulation of air between areas near the equator and subtropical areas of high pressure (see diagram below).

Where are the northeast trade winds?

The winds are northeasterly in the Northern Hemisphere and southeasterly in the Southern Hemisphere; hence they are known as the northeast trades and southeast trades, respectively. The trade winds are best developed on the eastern and equatorial sides of the great subtropical highs, especially over the Atlantic.

How do the trade winds work?

The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree “belt.” The sinking air triggers the calm trade winds and little precipitation, completing the cycle.

What are the northeast trade winds?

The northeast trade winds are prevailing winds in the Northern Hemisphere at approximately 30 degrees latitude, which have the ability to quickly propel a ship across the ocean. In the Southern Hemisphere, at 30 degrees South Latitude, winds blow from the southeast, creating the southeast trade winds.

Where do trade winds cancel each other out?

The trade winds from the Northern Hemisphere and the Southern Hemisphere meet in a zone ranging from 5 degrees North Latitude to 5 degrees South Latitude. In this Intertropical Convergence Zone, the winds cancel each other’s effect, causing a calm air in the area also called the doldrums.

What is the difference between trade winds and westerlies?

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. The westerlies: These winds are developed between 40° and 65°S latitudes and these latitudes are known as the Roaring Forties,…

How are trade winds formed?

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. The air eventually cools and sinks a bit further north in the tropics. This phenomenon is called the Hadley cell.
