What are trade winds explain?
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.
Why are they called trade winds?
A similar wind pattern occurs in the Southern Hemisphere; these winds blow from the southeast toward the northwest and descend near 30 degrees South latitude. … The trade winds are so named because ships have historically taken advantage of them to aid their journies between Europe and the Americas (Bowditch, 1995).
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 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.
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 is another name for 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).
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..
What are the main features 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.

What causes the trade winds to weaken?
The easterly trade winds are driven by a surface pressure pattern of higher pressure in the eastern Pacific and lower pressure in the west. When this pressure gradient weakens, so do the trade winds. The weakened trade winds allow warmer water from the western Pacific to surge eastward, so the sea level flattens out.
How are winds formed Class 9?
Winds are caused due to uneven heating of atmosphere. Air moves from high pressure area 1o a low pressure area. … So, wind blows from sea to land. During the night, the direction of wind is from land to sea as the earth cools faster than sea, creating a low pressure region above land.26 мая 2020 г.
What are seasonal winds?
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.
What is an example of local wind?
A local wind is a flow of air that tends to happen in a predictable way in a particular, local area. … 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.
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 …
What are Hawaii trade winds?
Trade winds in Hawaii are a phenomenon that occur as a result of high pressure systems that form in the North Pacific. They are generally a very steady presence in island weather and bring a constant wind or breeze from the North East or East North East directions.
