Best Answer

Tornadoes have had estimated winds as low as 60 mph. Below that it is debatable whether the circulation is a tornado.

How the force of power of a tornado measured?

The intensity of a tornado is determined by damage, wchi is used to estimate wind speed and assign it a rating from EF0 (weakest) to EF5 (strongest)


How is the power of a tornado determined?

The intensity of a tornado is determined by damage. Damage is examined and the tornado's peak wind speed is estimated. This is used to rate it on the Enhanced Fujita Scale which ranges from EF0 as the weakest to EF5 as the strongest.


Is there a way to measure a tornado?

Yes. The intensity of a tornado is estimated on the Enhanced Fujita scale. On this scale, engineers and meteorologists analyze damage and estimate the wind speed. The highest wind speed estimate is then used to assign a rating, ranging from EF0 for the weakest tornadoes to EF5 for the strongest.


How is force of a tornado recorded?

Engeineers and meteorologist examine the damage done by a tornado to estimate its peak wind speed. The tornado is then assigned a rating on the Enhanced Fujita Scale from EF0 (weakest) to EF5 (strongest) based on that information.


How do meteorologists infer a tornado's wind speed?

The wind speed of a tornado is inferred from the severity of the damage it inflicts.


What is the wind speed of a EF-0 tornado?

The estimated wind speed of an EF0 tornado is 65-85 mph.


What does tornado rated mean?

A tornado's rating is an assessment of its intensity on the Enhanced Fujita scale. Damage is analyzed to give an estimate of the tornado's peak wind speed, which is then used to assign it a rating ranging from EF0 for the weakest tornadoes to EF5 for the strongest tornadoes


How do they determine wind speed in a tornado?

In most cases the wind speed of a tornado is estimated based on the severity of the damage it causes.


What is the strongest wind for a tornado?

The actual maximum wind speed for a tornado is not known. The strongest wind ever recorded in a tornado was 302 mph.


What tool used to rate tornado strength?

Tornado strength is assessed on the Enhanced Fujita scale. It is not so much a tool as a set of guidelines. Meteorologists and engineers survey the damage done my a tornado, using it to estimate the wind speed at various points along the path. The highest wind speed is used to assign a rating, ranging from EF0 for the weakest tornadoes to EF5 for the strongest.


Which speed does the wind have to travel to be considered a tornado?

The enhanced Fujita scale shows winds for an EF0 (the weakest level) beginning at 65 mph, while the original scale starts F0 at 40 mph. However it is important to note that winds traveling at over 65 mph do not make a tornado. A tornado is defined as a violently rotating column of air extending from he base of a thunderstorm to the ground. Meaning that if the wind doesn't rotate and does not come from a thunderstorm then it is not a tornado, regardless of wind speed.


How do you rank tornadoes?

Tornadoes are rated on the Enhanced Fujita scale, which uses damage severity to estimate the tornado's wind speed and assign a rating ranging from EF0 at the weakest to EF5 at the strongest.
