What is the difference between winds and gusts

But the truth is, there is a very distinct difference between wind and wind gusts. A sustained wind is defined as the average wind speed over two minutes. However, gust can also occasionally occur over water due to changes in wind speeds and wind direction causing turbulence and friction in the region.

Gusts are formed over grounds due to friction between heavy cold air settling down and lighter thermal air rising.

So the higher the average wind speed the stronger is a gust. Besides average wind speed, other factors affecting gust are dynamics of the terrain, local topography, shape of the structure, and atmospheric pressure. A gust is defined as a sudden surge of strong winds that typically last less than twenty seconds and is followed by a lull.

Gusts are characterized by peak wind speed crossing 18 mph and a minimum of 10 mph difference between peak and lull wind speed. Winds are created when air flows from a region of high pressure to a region of low pressure. Wind speeds are measured using a device called an anemometer. A wind gust generally last under 20 seconds. The longer that gust lasts, the longer it exerts force on an object, and the higher the potential to cause damage.

By comparison, a sustained wind lasts several minutes. Although the force applied is less, it's applied for a much longer period of time. That force on an object causes stress and results in damage, sometimes worse than a strong wind gust. Open in Our App. Download it here.

Did the wind speed will increase or decrease due to gust wind please advise sir, This website is really helpfull Thanks and regards S.

There is a misconception in this article. Solar wind has nothing to do with wind on Earth. There is no gas between the sun and the earth, and solar wind refers to the flow of charged particles i. Hence the mention to solar wind should be removed from this article, as it is completely irrelevant. Name required. Email required.
