Trade winds that form over land (called continental trade winds)
are warmer and drier
than those that form over the ocean (maritime trade winds). The relationship between continental and maritime trade winds can be violent. Most tropical storms, including hurricanes, cyclones, and typhoons, develop as trade winds.
What is trade winds climate?
The trade winds are
the east to southeasterly winds
(in the Southern Hemisphere) which affect tropical and subtropical regions, including the northern areas of Australia. … It means that in both hemispheres, they tend to blow from the east to the west and towards the equator.
Are trade winds warm or cold?
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.
Why is it called trade winds?
The trade winds were
named by the crews of sailing ships that depended on the winds during westward ocean crossings
.
What do trade winds do to warm water?
Every 3 to 10 years, the southeast trade winds weaken, allowing the warm water to
flow further eastward toward
South America. … El Niño, also known as the warm-water phase of the ENSO, causes the water temperature off of South America to be warmer and prevents the upwelling of nutrient-rich cold water.
What are the main features of trade winds?
- 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.
Are westerlies trade winds?
The remaining air (air that does not descend at 30 degrees North or South latitude) continues toward the poles and is known as the westerly winds, or westerlies. 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 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.
Who discovered the trade winds?
It was the Genoese seaman, explorer and adventurer
Christopher Christopher Columbus
(1451-1506), who discovered the trade winds. These winds carried his three modest-size sailing vessels all across the Atlantic at its widest, from the Canary Islands to the Bahamas, a distance of 5400 miles, in 36 days, in 1492.
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.
What month does El Nino usually peak?
El Niño and La Niña episodes typically last 9-12 months. They both tend to develop during the spring (March-June), reach peak intensity during the
late autumn or winter (November-February)
, and then weaken during the spring or early summer (March-June).
How does the wind move during a fair weather?
Fair weather generally accompanies a high pressure center and
winds flow clockwise around a high
. This means that winds on the back (western) side of the high are generally from a southerly direction and typically mean warmer temperatures.
What causes the trade winds to weaken?
The air-sea interaction that occur during an El Niño event feed off of each other. As the pressure falls in the east and rises in the west,
the surface pressure gradient
is reduced and the trade winds weaken.
What happens when trade winds meet at the equator?
When it occurs within a trade wind regime, it is known as a trade wind inversion. The surface air that flows from these subtropical high-pressure belts toward the Equator is deflected toward the west in both hemispheres by the Coriolis effect
What causes the westerly winds?
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the
high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones
in this general manner.
What do you know about Itcz?
The Intertropical Convergence Zone, or ITCZ, is
the region that circles the Earth, near the equator
, where the trade winds of the Northern and Southern Hemispheres come together. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant.
