Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h). [312] A DOW calculation of a subvortice of the 2013 El Reno tornado was estimated in a range of 257–336 mph (414–541 km/h) in 2024. [313]
These low humidities, combined with the warm, compressionally-heated air mass, plus the high wind speeds, create critical fire weather conditions. The combination of wind, heat, and dryness accompanying the Santa Ana winds turns the chaparral into explosive fuel feeding the infamous wildfires for which the region is known.
A wind advisory is generally issued by the National Weather Service of the United States when there are sustained non thunderstorm winds of 31–39 miles per hour (50–63 km/h) and/or gusts of 46–57 miles per hour (74–92 km/h) over land. Winds over the said cap will trigger high wind alerts rather than a wind advisory

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 ...
In 1972, the National Hurricane Center (NHC) began ranking hurricanes according to wind speed with the Saffir–Simpson scale. A Category 3 has maximum sustained winds between 96 knots (110 mph; 178 km/h; 49 m/s) and 112 knots (129 mph; 207 km/h; 58 m/s). The NHC considers these winds to be sustained for a one-minute period at 10 metres (32.8 ...
A very strong typhoon has wind speeds between 85–104 kn (44–54 m/s; 98–120 mph; 157–193 km/h), while a violent typhoon has wind speeds of 105 kn (54 m/s; 121 mph; 194 km/h) or greater. [8] The HKO, SMG and the CMA also divide the typhoon category into three categories, with both assigning a maximum wind speed of 80 kn (41 m/s; 92 mph ...
