Frequent question: What scale is used to measure the violence of a tornado?

How does the EF scale work?

By looking at the amount of damage caused to different types of structures, scientists assign the storm an Enhanced Fujita scale classification. From the amount of damage they see, they then try to reverse engineer the storm’s wind speeds. As it tracks along the ground, a tornado’s power can change.

What scale is used to rate hurricanes?

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane’s maximum sustained wind speed. This scale does not take into account other potentially deadly hazards such as storm surge, rainfall flooding, and tornadoes. The Saffir-Simpson Hurricane Wind Scale estimates potential property damage.

What’s the difference between F5 and EF5?

Differences from the Fujita scale

The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.

What are the tornado Levels?

The Fujita Scale

F-Scale Number Intensity Phrase Wind Speed
F0 Gale tornado 40-72 mph
F2 Significant tornado 113-157 mph
F3 Severe tornado 158-206 mph
F4 Devastating tornado 207-260 mph

Is there a scale used to measure the intensity of thunderstorms?

In 2010, Henry Margusity, senior meteorologist for, unveiled the “TS Scale.” The scale rates thunderstorms from a weak TS1 to a dangerous TS5. Average rate of rainfall, maximum wind speeds, hail size, lightning frequency, tornado potential and capacity for damage are factors.
