Usually scientists do not use any tool to determine how strong a tornado is. Usually the strength of a tornado is determined based on the severity of damage it causes.
Occasionally wind speed measurements are obtained using Doppler radar, but such measurements are rare.
It usually requires a special kind of thunderstorm called a supercell. These storms have a powerful, rotating updraft called a mesocyclone. It is believed that if a mesocyclone intensifies rapidly it creates a downdraft, called a read-flank downdraft or RFD, near the back of the storm. This downdraft wraps around the bottom portion of the mesocyclone, tightening ans intensifying the rotation to produce a tornado. RFD winds can be very strong, sometimes exceeding 100 mph (160 km/h).

The Enhanced Fujita Scale (EF-Scale) classifies tornadoes based on their intensity and duration. It ranges from EF0 (weakest) to EF5 (strongest), with duration estimates typically based on damage assessments and eyewitness reports. Duration can vary widely depending on the tornado's strength and path.
The process of tornado formation starts when wind shear starts the updraft a a thunderstorm rotating, turning it into a supercell. If the right kind of down draft, called a rear-flank down draft occurs it can wrap around the rotating updraft, which is called a mesocyclone, and turn it into a more intense circulation: a tornado.
Before a tornado hits the ground, a rotating column of air forms in the storm cloud known as a funnel cloud. This funnel cloud extends towards the ground, and once it makes contact, the tornado is then officially considered to have touched down.
Because that's the kind of thing scientists do. They figure things out, sort them up in an orderly manner. Who's related to who, that kind of thing.
They are both kind of strong because a tornado can pick up objects and throw them. tsunamis can send big waves to wash off almost the whole island
Not by themselves, no. Most tornadoes form from a kind of severe thunderstorm called a supercell. These storms typically produce strong wind and heavy rain. These components can have some involvement in the formation of the tornado, but are not the direct cause. Much more is at work within the storm.
A violent windstorm that often takes the shape of a funnel is called a tornado.
the tornado kind
A tornado is a kind of vortex so yes, in some ways.
A tornado is itself a kind of vortex, and can have smaller vortices inside of it.
There is no specific type or rating for a tornado of a given size, though a mile wide tornado is likely to be very strong. The general term for a very large tornado (though not necessarily a mile wide), is "wedge."
A tornado emergency is a special kind of tornado warning that is issued when a large tornado is threatening a populated area. A tornado emergency indicates a more dangerous situation than an ordinary tornado warning.
waterspouts
A tornado is a violent microscale circulation with a low pressure center and forms from a thunderstorm.
Usually not, it generally takes an F4 or F5 tornado to do that kind of damage and only about 1% of tornadoes are that strong. Most tornadoes fall into the categories F0 and F1. These tornadoes can topple some trees, break windows, and strip roof surfaces.
