Question 786Navigation General

You are correct, the answer is B) wind speed. The Beaufort scale is a system used to estimate and describe wind conditions based on the observed effects of the wind on the physical environment. It specifically provides a measure of the wind speed, ranging from 0 (calm) to 12 (hurricane force). This makes B) wind speed the correct answer. The other answer choices are incorrect because the Beaufort scale does not measure wind direction (A), percentage of cloud cover (C), or barometric pressure (D). Those are separate meteorological factors that are measured using different methods and scales.
