What is the Beaufort scale used to measure?

The Beaufort scale is a standardized scale that measures wind speed and its effects at sea, as well as on land. It was developed in the early 19th century by Sir Francis Beaufort and links wind speed to observable conditions on the sea and the land, allowing mariners and meteorologists to communicate about wind conditions effectively. This scale ranges from calm conditions with a wind speed of zero to hurricane-force winds, providing a descriptive way to assess the wind's impact on the environment.

The other options do not accurately represent the purpose of the Beaufort scale. Atmospheric pressure, humidity levels, and temperature fluctuations are measured using different tools and scales, such as barometers for pressure, hygrometers for humidity, and thermometers for temperature. The unique focus of the Beaufort scale on wind speed and its corresponding effects is what distinguishes it from other meteorological measurements.
