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 ...
The National Weather Service issues a similar high wind warning (Specific Area Message Encoding code: HWW) for high winds on land. The criteria vary from place to place; however, in most cases, the warning applies to winds of 40 miles per hour (64 km/h) to 73 miles per hour (117 km/h) for at least 1 hour; or any gusts of 58 miles per hour (93 km/h) to 114 miles per hour (183 km/h) on land.
The most common way of describing wind force is with the Beaufort scale [3] that 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.

The purpose of the scale was to standardize wind reports in ship logs. The scale was ...
