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. For example, B = 9.5 is related to 24.5 m/s which is equal to the lower limit of "10 Beaufort". Using this formula the highest winds in hurricanes would be 23 in the scale.
A wind gust or just gust is a brief, sudden increase in the wind speed. It usually lasts for less than 20 seconds, briefer than a squall, which lasts minutes. A gust is followed by a lull (or slackening) in the wind speed. [1] Generally, winds are least gusty over large water surfaces and most gusty over rough land and near high buildings. [2]

The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
The previous morning, the same observer recorded a low of 54 degrees below zero.That 103-degree temperature change is not only America's highest 24-hour temperature change, but it's also a world ...
On June 30, 2021, at approximately 5:00 pm Edmonton South Campus reached a temperature of 37.4 °C (99.3 °F). This surpasses the previous 37.2 °C (99.0 °F) set on June 29, 1937. [ 5 ] [ 6 ] On July 2, 2013, a record high humidex of 44 was recorded, due to an unusually humid day with a temperature of 33.9 °C (93.0 °F) and a record high dew ...
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.
Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at 10 metres (33 ft) above mean sea level, [nb 1] and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ...
