Fujita scale
A scale created by Theodore Fujita to measure wind damage; the scale ranges from F0 (light damage) with a wind force up to 32 meters per second (72 miles per hour) to F5 (incredible damage) with a wind force above 117 meters per second (261 miles per hour). Fujita Scale (or F Scale) A scale of wind damage intensity in which wind speeds are inferred from an analysis of wind damage | ||||

Fujita Scale (or F Scale)
A scale of wind damage intensity in which wind speeds are inferred from an analysis of wind damage: F0 (weak): 40- 72 mph, light damage.
F1 (weak): 73-112 mph, moderate damage. F2 (strong): 113-157 mph, considerable damage. F3 (strong): 158-206 mph, severe damage. F4 (violent): 207-260 mph, devastating damage. F5 (violent): 261-318 mph, (rare) incredible damage.
All tornadoes , and most other severe local windstorms, are assigned a single number from this scale according to the most intense damage caused by the storm.

The Fujita scale (F-Scale), or Fujita-Pearson scale, is a scale for rating tornado intensity, based on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists (and engineers) after a ground and/or aerial damage survey; and depending on the circumstances, ground-swirl patterns (cycloidal marks), radar tracking, eyewitness testimonies, media reports and damage imagery, as well as photogrammetry/videogrammetry if video is available. | See more at Wikipedia.org... |
