(Entry 1 of 6) 1a : a natural movement of air of any velocity especially : the earth’s air or the gas surrounding a planet in natural motion horizontally. b : an artificially produced movement of air.
What is wind class 3?
A Wind Class 3 turbine is designed for an easy life with average wind speeds up to 7.5 m/s , and these turbines typically have extra-large rotors to allow them to capture as much energy as possible from the lower wind speeds they are subjected to.
What is wind Short answer?
Wind refers to the air movement from high pressure to low-pressure areas. It can be broadly divided into Permanent, periodic and local winds. Complete answer: In simple terms, the wind is nothing but moving air . The air movement is always from high pressure to low-pressure areas.
What is wind answer for kids?
Wind is the movement of air near Earth’s surface. Wind can be a gentle breeze or a strong gale . The most powerful wind happens during storms called tornadoes, cyclones, and hurricanes. Changes in the temperature of air, land, and water cause wind.

How do you explain wind?
Wind is moving air and is caused by differences in air pressure within our atmosphere . Air under high pressure moves toward areas of low pressure. The greater the difference in pressure, the faster the air flows.
What is wind class 7?

What is IEC’s wind class?
Wind classes determine which turbine is suitable for the normal wind conditions of a particular site . Turbine classes are determined by three parameters – the average wind speed, extreme 50-year gust, and turbulence. ... Turbulence is measured at 15 m/s wind speed. This is the definition in IEC 61400-1 edition 2.
What is wind classification?
Wind classification is the term used by building engineers and other construction professionals to measure the gust wind speeds (m/s) that affect a given site .
Why is wind important to humans?
Wind is a renewable energy source . Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. ... Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions.
What is wind short answer for Class 1?
He told me the simple answer: Wind is moving air . We thought you might want to know more about how it works. Wind happens both because of how the Sun heats up the Earth and the tiny air molecules that move around us all the time. You can’t see these air molecules, but they still have weight and take up space.
What is called in wind?
Short bursts of high speed wind are termed gusts . Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane.
What is the full meaning of wind?
wind, air current , current of air(noun) air moving (sometimes with considerable force) from an area of high pressure to an area of low pressure.
