Answer:
The Beaufort Scale or Beaufort Wind Force Scale is a system for estimating wind strengths without the use of instruments, based on the effects wind has on the physical environment. The behaviour of smoke, waves, trees, etc., is rated on a 13 point scale of 0 (calm) to 12 (hurricane).



What is Beaufort Scale?
[tex] Beaufort [/tex] [tex] Scale [/tex] is the measurement of the wind strength or wind speeds. This was invent by [tex] Admiral [/tex] [tex] Beaufort [/tex] in 1806. Admiral Beaufort used numbers to describe or to measure the wind strengths or speeds.
Beaufort Scale
Force - Strength - Kph
0 - Calm - 0-1
1 - Light Air - 1-5
2 - Light Breeze - 6-11
3 - Gentle Breeze - 12-19
4 - Moderate Breeze - 20-29
5 - Fresh Breeze - 30-39
6 - Strong Breeze - 40-50
7 - Near Gale - 51-61
8 - Gale - 62-74
9 - Strong Gale - 75-87
10 - Storm - 88-101
11 - Violent Storm - 102-117
12 - Hurricane - 118+
