Empirical
The word empirical denotes information gained by means of observation, experience, or experiment, as opposed to theory. A central concept in science and the scientific method is that all evidence must be empirical, or empirically based, that is, dependent on evidence or Logical consequence that are observable by the senses....

The very weak tornadoes, low to mid EF0, have winds that would be an 11 on the Beaufort scale. Mid EF0 (EF0 wind estimates: 65-85mph) tornadoes and higher would be a 12.
The tornadoes responsible for major damage (EF3 or higher on the Enhanced Fujita scale) have winds in excess of 135 mph, in rare cases as high as 300mph.

Storm force on the beaufort scale
Usually force 12 (Hurricane Force), but after Typhoon Chanchu, Some countries extended it up to 17 (Hurricane Force-5?)
The Beaufort scale is used to estimate the wind force.
The Beaufort Scale
A Richter scale used to express the energy released by an earthquake A Beaufort scale is used to derermine the sthrenth of wind.
Beaufort scale :)
A wind of 64 to 71 knots is a hurricane force wind.
The Highest measurement of Beaufort scale is 12, which refers to Hurricane-force.
Sir Frances Beautort invented the Beaufort scale for measuring wind speeds.
This scale is called the Beaufort scale.
The Beaufort scale.
The Beaufort wind force scale, or simply Beaufort scale, was devised at the beginning of the 19th century (around 1805) to provide a standard measure of wind speeds for sailors.
Force 12 is hurricane force.
The Beaufort scale is a measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort Wind Force Scale, although it is a measure of wind speed and not of "force" in the scientific sense of the word.
