What is the Beaufort scale used for?

The Beaufort scale is specifically designed to estimate wind speed by observing the conditions of the sea and land features. It provides a systematic way to estimate wind speeds based on visual assessments of the effects of wind on the environment, such as the state of the sea (e.g., wave heights, water surface conditions) and the influence on terrestrial objects (e.g., trees, flags, smoke). This scale allows for a standardized reference that can be used globally, making it particularly valuable for sailors, meteorologists, and those involved in maritime activities.

Other options involve concepts related to meteorological observations but do not align with the primary purpose of the Beaufort scale. Temperature changes, atmospheric pressure assessment, and humidity levels are evaluated using entirely different instruments and methods, such as thermometers, barometers, and hygrometers. The Beaufort scale’s specific focus on wind speed through visible environmental indicators distinguishes it as a unique tool in meteorology.
