Sir Francis Beaufort. The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before). In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective — one man's "stiff breeze" might be another's "soft breeze"—: Beaufort succeeded ...
Beaufort Wind Scale; 0 1 2 3 4 5 6 7 8 9 10 11 12; Calm: Light Air: Light Breeze: Gentle Breeze: Moderate Breeze: Fresh Breeze: Strong Breeze: Near Gale: Gale: Strong ...
The Beaufort Wind Scale applies visual clues to gauge how fast the wind is blowing. Watches, advisories and warnings. Anytime a significant weather event is expected, the Weather Service will ...
The most common way of describing wind force is with the Beaufort scale [3] which defines a gale as wind from 50 kilometres per hour (14 m/s) to 102 kilometres per hour (28 m/s). It is an empirical measure for describing wind speed based mainly on observed sea conditions.
Before the 1–5 scale was created in 1969 by the National Hurricane Center and later by the Bureau of Meteorology in Australia, many tropical cyclones were simply ranked by the Beaufort Wind Scale which was created in the early 1800s by Francis Beaufort. The purpose of the scale was to standardize wind reports in ship logs. The scale was ...
Wind direction is given first, then strength (on the Beaufort scale), followed by precipitation, if any, and (usually) lastly visibility. Change in wind direction is indicated by "veering" ( clockwise change) or "backing" (anti-clockwise change).
The scale used for a particular tropical cyclone depends on what basin the system is located in; with for example the Saffir–Simpson hurricane wind scale and the Australian tropical cyclone intensity scales both used in the Western Hemisphere. All of the scales rank tropical cyclones using their maximum sustained winds, which are either ...
