Beaufort Wind Scale is an empirical measure that relates wind speed to observed conditions. Which choice best describes its basis?
Correct Answer:
An empirical scale relating wind speed to observed conditions
Explanation:
The key idea here is that the Beaufort Wind Scale is built on empirical observation—it's a way to judge wind strength by what the wind does to the environment, not by a measurement from a device. Historically, sailors described wind as it affected sails, the sea state, flags, smoke, and trees, and those observed effects were translated into numbered categories. That means the scale is qualitative and based on real-world phenomena, not an instrument reading or a map. So the best description is that it’s an empirical scale relating wind speed to observed conditions. The other options describe things that aren’t what the Beaufort scale is about: it isn’t a measure of ship stability, it isn’t a direct measure of current speed from a device, and it isn’t a wind direction map.
