Assumptions
The Beaufort Wind Scale assigns numbers from 0 to 12 that correlate to a gradient scale of wind velocity and name classification. Meteorologists refer to the wind velocity number 12 on the scale as a hurricane, indicating that the wind velocity is above 65 knots. At the opposite end of the scale, a 0 may include a wind velocity of up to 1 knot, and is called "calm" under the established system.
Which of the following was an assumption made by the creators of the Beaufort Wind Scale?
Which of the following was an assumption made by the creators of the Beaufort Wind Scale?
Answer Choices
Sign in to reveal the correct answerA
Meteorologists learn the Beaufort Wind Scale in order to classify the level of wind from "calm" to "hurricane."
B
Wind velocity may be measured accurately enough to classify it on a scale from 0 to 12.
C
If a scale assigns names to wind velocity, there must be a corresponding number also assigned.
D
Because it is difficult to measure wind velocity exactly, the Beaufort Wind Scale refers to "calm" as 0, but the wind may be blowing as much as 1 knot.
E
The Beaufort Wind Scale is the most accurate and effective scale for expressing wind velocity.
