Unlike a hurricane there is no minimum set wind speed for a tornado. Although officially the lower bound for an EF0 tornado is 65 mph, tornadoes have been rated EF0 with winds estimated as low as 55 mph.
It is not the wind speed that makes the tornado, though as winds much stronger than this can occur with other events. A tornado is defined by the fact that its winds rotate violently about a center in a vortex extending from the base of a thunderstorm to the ground.
A tornado is not really considered ordinary wind. A tornado is defined as a violently rotating column of air extending from the base of a thunderstorm to the ground, so wind of a given intensity isn't usually considered a tornado unless it rotates according to that definition.
Additionally there is no set minimum wind speed for a tornado to form, partially because only a few ground level wind measurements have actually been taken from inside a tornado. Though it is generally accepted that the winds must be strong enough to do damage.
There are three scales that measure tornado intensity and provide wind estimates: the Fujita (F) scale, the TORRO (T) scale, and the Enhanced Fuijta (EF) scale.
The weakest levels on both the F and T scales (T0 and F0) have wind estimates starting at 40 mph. The EF scale starts EF0 at 65 mph.
Wind speed alone does not make a tornado. A tornado is defined a a violently rotating column of air extending from the base of a thunderstorm to the ground. If it does not meet this definition it is not a tornado no matter how strong the wind is. There does not appaer to be a set minimum. The Ehnaced Fujita scale sets the lower bound for EF0, the lowest category, at 65 mph, but EF0 tornadoes have been asses with winds lower than this.
65-200+ mph. However, just because winds reach these speed does not mean there is a tornado.
If you look at the Enhanced Fujita scale EF0 winds start at 65 mph, though damage is possible as low as about 50 mph.
If you are asking about a "category 5" hurricane classification the winds need to be 157 miles per hour or faster.
Not a real tornado of course. But if you take a glass of water and swirl it the soap bubbles will make the vortex more visible.
Because of the hurricanes are very harmful. Also it ruins the houses. It affects the winds. Thank you From wikianswers.com hope you come here again Because we have all of the answers you need!
Yes, hurricane force winds are defined as 74 mph or higher.
Doppler radar is perhaps the most important tool in tracking tornadoes.
There is no definite starting point. Officially an EF0 tornado starts at 65 mph, but some have been rated with winds as low as 55 mph. However it is not wind speed alone that qualifies a tornado. Fire whirls, or whirlwinds spawned by fires, have had winds over 100 mph but don't count as tornadoes because they are not associated with thunderstorms and usually do not connect to cloud base. Dust devils, which form on hot, sunny days can, on rare occasions, have winds equivalent to an EF0 tornado, but for the same reason as fire whirls are not considered tornadoes.
You cannot make a tornado. The primary materials in a tornado are air and water vapor, but the dynamics that create a tornado are complex, impossible to control, and not completely understood.
If you are asking about a "category 5" hurricane classification the winds need to be 157 miles per hour or faster.
Strong winds alone cannot create a tornado. Tornadoes need a specific setup of air movement within a thunderstorm in order to develop. That said, one component believed to play a key role in tornado formation is something called a rear-flank downdraft, or RFD. Winds from the RFD can reach or exceed 80 mph. In terms of tornadoes themselves, 80 mph would be near the upper end of the estimated wind range of an EF0 tornado (65-85 mph).
Nope, of course not, you don't need to worry. It just means that some winy weather is coming to get you, yea you;) rotating clouds means there's a storm.
different temp air mixing and spining

you do not need a tornado first of all, and their is no cheat for a tornado, it is a mod for the pc.
you'll need a white apricorn to make fast ball, then go to Kurt to make it a fast ball.
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.
