What causes the trade winds?
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 main characteristics of westerlies?
The main characteristics of the Westerlies are: They blow from sub-tropical high pressure belts to the sub-polar low pressure belts between 30° to 60°N of the Equator in the temperate latitudes.
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 is the meaning of trade winds?
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth’s equatorial region. Trade winds have been used by captains of sailing ships to cross the world’s oceans for centuries.

What are trade winds Class 9?
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 the 4 types of winds?
The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind belts. There are three other types of wind belts, also. They are called Trade Winds, Doldrums, and Horse Latitudes.
How are trade winds related to monsoon winds Class 9?
Answer: Trade winds blow in the tropics throughout the earth,monsoon winds blow only in the indian ocean region during a particular season (northeast during winter and southwest during summer) and influence trade winds to cause complete reversal of direction according to the direction of monsoon winds.
Why trade winds are called easterlies?
If they move from east to west, they are called easterlies. There are winds because there are differences in pressures. The direction of wind is also affected by coriolis affect.
What are the three main types of winds?
The different types of winds on earth are planetary winds, trade winds, periodic winds, local winds, and westerlies.
Are trade winds and easterlies same?
Hemisphere. Near the earth’s surface at tropical (low) latitudes, the prevailing wind is from the east. These are called easterlies, and are also known as the trade winds.
How are winds named?
A wind is always named according to the direction from which it blows. For example, a wind blowing from west to east is a west wind. The ultimate cause of Earth’s winds is solar energy. The greater the difference in pressure, the greater the force and the stronger the wind.

What are the main types of winds?
The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums. Polar easterlies are dry, cold prevailing winds that blow from the east.
What are the 2 main types of winds?
Wind blowing above the earth surface may be classified into five major types:
- Planetary winds.
- Trade winds.
- The westerlies.
- Periodic winds. Monsoon winds. Land breeze. Sea breeze. Mountain and valley breeze.
- Local winds.
What are the three main types of winds Class 7?
