Wind speed on the Beaufort scale is based on the empirical relationship: [6] v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...
Still in the competition, Powell then needed to jump over the world record to win the competition. He succeeded, and the wind had died down to only +0.3, enough to record a legal wind for the record as well. In a later competition, Powell jumped 8.99, also in Sestriere, but without setting a record due to a +4.4 wind.
After wind speeds lessened over the weekend and firefighters made progress against the deadly blazes in Southern California, gusty Santa Ana winds are returning to the region this week, raising ...
Wind speeds over 75 miles per hour are classified as “hurricane force,” capable of pushing moving vehicles off the highway, overturning mobile homes and peeling off roofs. The average wind ...
Wind speeds over 99 knots are extracted by subtracting 50 from the direction and adding 100 to the speed. Thus, for example, the wind forecast for Abilene (ABI) at 30,000 feet, shown above as 7603, indicates a forecast wind of 260 degrees at 103 knots (76-50=26 or 260, and speed became 100+03=103).
The Met Office warned of “damaging winds” with gusts of 90mph possible over the coasts and hills of West and South Wales. Forecasters say the strongest winds will begin to ease from late morning.
The term "squall" is used to refer to a sudden wind-speed increase lasting minutes. In 1962 the World Meteorological Organization (WMO) defined that to be classified as a "squall", the wind must increase at least 8 metres per second (29 km/h; 18 mph) and must attain a top speed of at least 11 metres per second (40 km/h; 25 mph), lasting at least one minute in duration.
