What is the definition of trade winds


What are called trade winds?

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. … The trade winds are air currents closer to Earth’s surface that blow from east to west near the equator.

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 is the nautical definition of trade winds?

The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth’s equatorial region (between 30°N and 30°S latitudes).

What is a simple definition of wind?

wind. [ wĭnd ] A current of air, especially a natural one that moves along or parallel to the ground, moving from an area of high pressure to an area of low pressure. Surface wind is measured by anemometers or its effect on objects, such as trees.

What are trade winds Class 9?

Trade winds are a persistent wind that 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 trade winds warm or cold?

The differences in pressure and temperature between the two sides of the Pacific are caused by the trade winds; air blowing from east to west pushes water, making the sea level higher in the western Pacific, and makes cold water rise toward the surface, making the eastern Pacific approximately 14 degrees F (7.7 degrees …12 мая 2020 г.

What are the characteristics of trade winds?

The main characteristics of the Trade winds are:

  • The Trade winds blow in the tropics between the sub tropical high pressure belt to the equatorial low pressure belt between 30°N and 30°S.
  • Trade winds are warm winds and hence they pick up moisture and bring heavy rainfall on the eastern sides of the tropical islands.

Why are northeast trade winds dry?

Trade winds originate over land and they don’t carry much of moisture.. This cause lack of rainfall in the regions they blow over and causes dry atmosphere..

Are trade winds cold?

The trade winds, especially in the eastern Pacific, convey relatively cool air toward the Equator; in moving, the air comes in contact with the sea and thus becomes increasingly humid and warm, and high lapse rates (the term used to denote the rate of change of air temperature with increasing height above sea or land …

Are trade winds strong?

The prevailing winds at the horse latitudes vary, but are usually light. Even strong winds are often short in duration. Trade winds are the powerful prevailing winds that blow from the east across the tropics. Trade winds are generally very predictable.

What is the meaning of Coriolis force?

a fictitious force used to explain a deflection in the path of a body moving in latitude relative to the earth when observed from the earth. The deflection (Coriolis effect) is due to the earth’s rotation and is to the east when the motion is towards a pole.

What is a northeasterly wind?

When a wind is described as a Northeasterly or Southwesterly, is that the direction it is travelling, or where it came from? … So a northeasterly wind blows from the northeast, and so on. As an example, a helium balloon released in a southeasterly wind will travel toward the northwest.

What is the best definition of wind?

the westerly movement of air above the Earth’s surface D. the movement of air between two objects that are in contact.

What are the two meanings of wind?
