Parameters
The six categories for the EF scale are listed below, in order of increasing intensity. Although the wind speeds and photographic damage examples are updated, the damage descriptions given are those from the Fujita scale, which are more or less still accurate. However, for the actual EF scale in practice, damage indicators (the type of structure which has been damaged) are predominately used in determining the tornado intensity.
| Scale | Wind speed (Estimated) |
Example of damage | |
| mph | km/h | ||
| EF0 | 65–85 | 105–137 | |
| EF1 | 86–110 | 138–178 | |
| EF2 | 111–135 | 179–218 | |
| EF3 | 136–165 | 219–266 | |
| EF4 | 166–200 | 267–322 | |
| EF5 | >200 | >322 | |

Famous quotes containing the word parameters:
“What our children have to fear is not the cars on the highways of tomorrow but our own pleasure in calculating the most elegant parameters of their deaths.”
—J.G. (James Graham)
“Men have defined the parameters of every subject. All feminist arguments, however radical in intent or consequence, are with or against assertions or premises implicit in the male system, which is made credible or authentic by the power of men to name.”
—Andrea Dworkin (b. 1946)
