The strength of winds is measured with the help of-
-
A.
Barometers
-
B.
Beaufort scale
-
C.
Wind indicator
-
D.
Tintometer
Correct Answer:
B. Beaufort scale
Explanation:
The Beaufort scale is an empirical system used to estimate wind strength and speed based on its observable effects on land and sea. Developed by Sir Francis Beaufort in 1805, the scale ranges from 0 for calm conditions to 12 for hurricane-force winds. While instruments like anemometers provide precise numerical data, the Beaufort scale remains a standard meteorological tool for classifying wind intensity through visual cues, such as the movement of trees or the formation of waves. Other options like barometers measure atmospheric pressure, while tintometers are used to determine color intensity.
