This is continuation with my earlier post of Wind speed and Wind Direction. Below is a wind chart, created by Admiral Beaufort. Beaufort arranged the numbers 0 to 12 to indicate the strength of the wind from calm (force 0) to hurricane (force 12).

The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity based on observed sea conditions.
