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.
The rear of the Wall of Wind. The Wall of Wind (WoW) is a large scale wind engineering testing facility at Florida International University.The original version, with two fans, was completed in 2005 and upgraded to six fans in 2007—sufficient to generate winds of up to 120 miles per hour (190 km/h).
The wind profile power law relationship is = where is the wind speed (in metres per second) at height (in metres), and is the known wind speed at a reference height .The exponent is an empirically derived coefficient that varies dependent upon the stability of the atmosphere.

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 ...
Near the tornado's peak intensity, they recorded a wind speed of 115–120 meters per second (260–270 miles per hour; 410–430 kilometers per hour). Though the portable radar had the uncertainty of ±5–10 metres per second (11–22 mph; 18–36 km/h), this reading was probably within the F5 range, confirming that tornadoes were capable of ...
training of wind tunnel personnel. Besides, results from wind tunnel tests of standard models are used as test cases for verification of computational-fluid-dynamics computer codes. In most wind tunnels, standard models are tested during the commissioning and calibration [2] [3] [4] of the facility.
Just because it’s hot in the summer doesn’t mean it won’t rain. Make sure you are ready when the rain comes with these umbrellas.
