What is trade winds climate?
The rising air is associated with deep atmospheric convection, heavy precipitation, and weak wind speeds, with an influence on global weather patterns Air heated by the sun rises and releases moisture through rain and thunderstorms. … Once the air cools, it descends as drier air.
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.
How does trade wind influence the climate of tropical region?
Hot, moist air rises near the equator, and as it rises it cools and drops heavy rain in tropical areas.
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.
How do winds affect the climate?
Wind carries moisture into an atmosphere, as well as hot or cold air into a climate which affects weather patterns. Therefore, a change in wind results in a change of weather. … Additionally, heat and pressure cause the wind to shift direction.
What affects 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 trade winds in India?
The low pressure area attracts south-east trade winds. Due to coriolis force, these trade winds turn right towards the low pressure areas in India after crossing the equator and start blowing in the southwestern direction. Thereafter these trade winds enter the peninsular part of India as the south-west monsoon.
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. …
Why do trade winds occur?
Trade winds are caused by the strong warming and evaporation within the atmosphere around the equator. (1) Around the equator, the warm air rises rapidly, carrying a lot of moisture. … (4) There, it changes direction and flows back towards the equator, to restart the circulation process.
How do North East trade winds affect the climate of India?
During the winter season, North-East trade winds prevail over India. They blow from land to sea and that is why that for most part of the country, it is a dry season. … They gather moisture which causes rainfall in the Coromandal coast while the rest of the country remains dry.
What is the relation of trade winds to the global climate?
And yet wind patterns in the tropical Pacific can influence climate worldwide; strong trade winds in the tropical Pacific pull heat out of the atmosphere and drive it down into the ocean, causing global warming to slow, while weaker trade winds allow more heat to escape into the atmosphere, accelerating global warming.
What creates the trade winds and on what part of earth do these winds originate?
The coriolis effect, an offshoot of the Earth’s rotation, makes moving air masses curve, so that the winds converging on the Equator come from the northeast in the Northern Hemisphere and the southeast in the Southern Hemisphere. These winds are called the trade winds.
Why do trade winds 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 are trade winds called?
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth’s equatorial region.
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.
