"Beaufort Scale" is a measure of?

Correct option is A

The Beaufort Scale is a standardized scale used to measure wind velocity (speed) based on observed sea conditions or land effects. It was developed by Admiral Francis Beaufort of the British Navy in 1805 and ranges from 0 (calm) to 12 (hurricane-force winds). The scale categorizes wind intensity using qualitative descriptions such as "gentle breeze," "gale," and "storm."

Information Booster:

1. The Beaufort Scale categorizes wind speeds from 0 (calm) to 12 (hurricane-force winds).
2. It is widely used in maritime navigation, meteorology, and aviation.
3. The scale originally relied on visual observations but now correlates with precise wind speed measurements.
4. Wind velocity influences ocean waves, tree movement, and structural integrity.
5. The highest levels (Beaufort 12 and above) correspond to extreme storms like hurricanes or typhoons.
