What specific meteorological instrument scale is utilized to measure wind velocity?
Show answer Hide answer
Answer: B. Beaufort Scale
Explanation
The Beaufort scale is an empirical measure that relates wind speed to observed conditions on land or at sea. Sir Francis Beaufort developed this observational scale to help sailors estimate wind velocity without complex instruments. Each numerical category on the scale corresponds to specific observable wind effects on waves, trees, and structures. Wind velocity measures the speed and direction of moving air masses across the surface of the Earth. Modern meteorology combines this classical observational scale with digital anemometer readings for precise forecasts. The scale ranges from calm conditions represented by zero up to catastrophic hurricane-force winds at the top.
Richter scale measures the magnitude of seismic energy released by earthquakes rather than atmospheric wind velocity. Meter-second scale is a unit of measurement rather than a recognized meteorological scale for classifying wind force. The option stating none of these is incorrect because the Beaufort scale is the standard observational wind measure.
