Fastest ever recorded: 484±32 km/h (301±20 mph) (3-second gust); calculated by a DOW (Doppler On Wheels) radar unit in the 1999 Bridge Creek–Moore tornado between Oklahoma City and Moore, Oklahoma, USA, 3 May 1999. Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h).
Average wind speeds "blowing off the prairie" are greater in the Chicago area. Statewide, the wind speeds average 8 to 12 miles per hour (13 to 19 km/h), and is greater in the winter than in summer.

A wind rose plot may contain additional information, in that each spoke is broken down into color-coded bands that show wind speed ranges. Wind roses typically show 8 or 16 cardinal directions , such as north (N), NNE, NE, etc., [ 2 ] although they may be subdivided into as many as 32 directions .

[ 1 ] The first known repeated effort to label Chicago with this nickname is from 1876 and involves Chicago's rivalry with Cincinnati .
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 ...
