Beaufort Wind Scale
Beaufort number --> Effects --> Wind conditions
0 smoke rises vertically from chimneys calm, less than 1 km/h
1 smoke from chimneys is deflected light breeze from 1 to 5 km/h
2 moves a weather vane light breeze, from 6 to 11 km/h
3 makes a flag fly light breeze, from12 to 19 km/h
4 flutters papers and move small tree branches, moderate breeze, 20 to 28 km/h
5 creates waves on a lake and moves bushes breeze, from 29 to 38 km/h
6 makes an umbrella difficult to use and wind from 39 to 49 km/h moves large branches
7 walking becomes difficult wind, from 50 to 61 km/h
8 breaks small branches wind from 62 to 74 km/h
9 lifts shingles on roofs, wind from 75 to 88 km/h
10 uproots trees and causes property damage, wind from 89 to 102 km/h
11 storm causing heavy damage, wind from 103 to 118 km/h very rare conditions
12 hurricane causing devastation, wind from 119 to 220 km/h
Fujita or F-Scale of Tornado Strength
F-scale Wind speed (km/h) --> Damage
F0 64 to 116 km/h - little damage
F1 117 to 180 km/h - moderate damage
F2 181 to 253 km/h - considerable damage
F3 254 to 331 km/h - severe damage
F4 332 to 418 km/h - site devastated
F5 419 to 512 km/h - unbelievable damage!
