By the estimates of the Enhanced Fujita scale EF0 tornado winds start at 65 mph. However, this is only an estimate.
It is rare to get direct measurements from inside a tornado.
Note, however that whether or not a tornado has occurred is not defined by the wind speed, but by the manner in which it moves. A tornado is a violent vortex of wind in contact with the cloud base and the ground.
That varies. If you are close enough to be in the area of the tornado's inflow then the wind will blow almost directly towards the tornado, perhaps a little to the right of that direction. In that case the wind direction will depend on where the tornado is relative to you. If you are beyond the inflow area for the tornado, then nothing about the wind direction would indicate the approaching tornado.
The largest tornado ever recorded was the El Reno, Oklahoma tornado of May 31, 2013. This tornado was 2.6 miles wide. Doppler radar measured a wind gust in the tornado at 296 mph, the second highest wind speed ever recorded in a tornado.
For a tornado to form, you need three main ingredients: warm, moist air close to the ground; cooler, drier air above it; and strong wind shear (a change in wind speed or direction with altitude). These conditions create a rotating updraft that can develop into a tornado under the right circumstances.
There is no solidly set minimum wind speed for a tornado. The Enhanced Fujita scale starts an EF0 at 65 mph, but tornadoes have occurred with estimated winds lower than that. Tornadoes are defined by the amnner in which the air moves rather than the wind speed. A tornado is a rotating vortex of strong wind that onnects to both the ground and the cloud base.
The strong wind in a tornado is the source of its destructive potential.
A tornado can happen when the wind spins in a circle, wind spins around near and during a thunderstorm, and when hot and cold air meet. Most tornadoes happen May - August, summer for most people. But be aware, tornadoes can happen any time, anywhere, and in any thunderstorm or hurricane
It is caused when wind, usually created by the fire itself, whips the fire into a sprial.
A tornado IS wind- very fast winds spinning in a circle.
The wind of a tornado are in a much smaller area, usually under a mile wide. A hurricane is hundreds of miles wide.
No. The pressure drop inside a tornado is not large enough for this to happen. Tornadoes tear houses apart with the power of their wind.
Yes, in simplest terms a tornado is a vortex of very strong wind.
That varies. If you are close enough to be in the area of the tornado's inflow then the wind will blow almost directly towards the tornado, perhaps a little to the right of that direction. In that case the wind direction will depend on where the tornado is relative to you. If you are beyond the inflow area for the tornado, then nothing about the wind direction would indicate the approaching tornado.
The rotation in a tornado is driven by the wind shear, which is the change in wind speed and direction with height. This wind shear creates a horizontal rotation that is then tilted vertically by updrafts in the storm, leading to the spinning motion of the tornado.
Before a tornado occurs, the atmosphere needs to be unstable, with warm, moist air at the surface and cold, dry air aloft. Wind shear is also crucial, as it creates the rotation necessary for a tornado to form. Storm systems or supercell thunderstorms often provide the ideal conditions for tornado development.
A tornado is basically just a vortex of wind
The largest tornado ever recorded was the El Reno, Oklahoma tornado of May 31, 2013. This tornado was 2.6 miles wide. Doppler radar measured a wind gust in the tornado at 296 mph, the second highest wind speed ever recorded in a tornado.
A 45 mph wind would not to much damage at all. A few tree limbs may break and some trees may fall, but that is likely the worst that will happen. Because of the lack of damage it will be difficult to verify that a tornado ocurred and the event will likely not even be counted.
