Beaufort Wind Scale - National Weather Service
One of the first scales to estimate wind speeds and the effects was created by Britain's Admiral Sir Francis Beaufort (1774-1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations. The scale starts with 0 and goes to a force of 12. The Beaufort scale is still used today to estimate wind strengths.
Beaufort scale - Wikipedia
A ship in a force 12 ("hurricane-force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale (/ ˈ b oʊ f ər t / BOH-fərt) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.

Wind stings face in temperatures below 35 deg F (2C). Slight effort in maintaining balance against wind. Smoke rises at about 15 deg. Both slack and taut halyards whip slightly in bent position. Low moaning, rather than whistle, in the rigging. Heavy flag extends and flaps more vigorously.

The Beaufort Scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. Below is a table showing the Beaufort Scale with speeds in knots, miles per hour and kilometres per hour.

The Beaufort Scale was devised by Admiral Sir Francis Beaufort in 1805/06. It is a way of estimating the wind strength according to the appearance of the sea (or on land, largely by the response of trees).

Beaufort wind force scale - Met Office
The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity based on observed sea conditions. These values refer to well-developed...

Learn to measure wind speed and power conditions by the Beaufort scale
How to read the Beaufort scale chart? If you have exact data about wind speed, you can connect it with the Beaufort scale number using the following chart, where you see Beaufort number from 0 to 12 and wind description in the beginning, then — water and land conditions.
How to Measure Wind Speed: The Beaufort Wind Force Scale
This scale quantifies wind intensity based on observed sea conditions, offering a standardized measure of wind strength. From calm (Force 0) to hurricane force (Force 12), each level describes the wind’s effects on the sea’s surface, from ripples to towering waves.
Wind stings face in temperatures below 35 deg F (2C). Slight effort in maintaining balance against wind. Smoke rises at about 15 deg. Both slack and taut halyards whip slightly in bent position. Low moaning, rather than whistle, in the rigging. Heavy flag extends and flaps more vigorous.
Beaufort's Wind Scale - The Engineering ToolBox
The Beaufort wind scale is divided into series of values, from zero for calm winds, up to twelve and above for hurricanes. Each value represents a specific range and a classification of wind velocity with an accompanying descriptions of the effects on surface features.

Tropical cyclone intensity scales - Wikipedia
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 ...
