Tornadoes need moisture and warm air to form, which is unusual at that latitude. Plus tornadoes or their evidence have to be observed by someone, and the Arctic Circle has few residents! Do tornadoes really stay away from gullies, rivers and mountains? A gully could actually make a tornado more intense, just as an ice skater spins faster when he or she stands up tall and stretches their arms up straight over their heads. Every major river east of the Rockies has been crossed by a significant tornado, and high elevations in the Appalachians, Rockies, and Sierra Nevada have all experienced tornadoes.
Do tornadoes always come from a wall cloud? A wall cloud is not always present. It is also possible that you cannot see a wall cloud because of your viewing angle. What does a tornado sound like? People who have been in a tornado say it sounds like a jet engine or a freight train and is very loud.
Days to Make a Change
They said it hurt their ears, but they were more worried about what might happen to them than they were about the pain in their ears. Can tornadoes be stopped? You have to consider that the tornado is part of something bigger: the supercell thunderstorm. Unless you disrupt the supercell thunderstorm itself, you would likely have another tornado, even if you were able to destroy the first. The thunderstorm's energy is much greater than the tornado. No one has tried to disrupt the tornado because the methods to do so could likely cause even more damage than the tornado. Detonating a nuclear bomb, for example, to disrupt a tornado would be even more deadly and destructive than the tornado itself.
Lesser things like huge piles of dry ice or smaller conventional weaponry would be too hard to deploy in the right place fast enough, and would likely not have enough impact to affect the tornado much anyway.
What is the difference between a tornado watch and a tornado warning? A tornado watch defines an area where tornadoes and other kinds of severe weather are possible in the next several hours. It means that you need to be alert, and be prepared to go to safe shelter if tornadoes happen or a warning is issued. Tune in to local TV, radio or internet for more information. A tornado warning means that a tornado has been spotted, or that Doppler radar shows a thunderstorm circulation which can spawn a tornado.
When a tornado warning is issued for your area, seek safe shelter immediately. The Storm Prediction Center issues tornado and severe thunderstorm watches.
Your local National Weather Service offices issue tornado warnings. What would it be like to be in the eye of a tornado? The very center of the tornado is probably almost calm, but may have some downward motion in it. There have not been any direct measurements of the winds because the instruments used to measure wind speed can't survive long enough to measure the eye. How many tornadoes hit the US each year? About I have a theory about tornadoes; who do I talk to? We receive literally hundreds of ideas for observing, controlling, or stopping destructive storms.
Our scientists are likely to look at ideas that are investigated by a researcher who publishes the results in a peer-reviewed journal. In this way they can review, and if necessary, replicate the results, which then will suggest the next step to move the science forward. I would like to volunteer to help NSSL during a tornado intercept field project. Unfortunately, government regulations make it impossible to accept offers from the public to do volunteer field work for any tornado intercept programs.
Legal liability questions prevent NSSL from accepting volunteers, even at their own risk. How is the strength of a tornado determined? The most common and practical way to determine the strength of a tornado is to look at the damage it caused. From the damage, we can estimate the wind speeds. The EF-Scale takes into account more variables than the original Fujita Scale F-Scale when assigning a wind speed rating to a tornado, incorporating 28 damage indicators such as building type, structures and trees.
For each damage indicator, there are 8 degrees of damage ranging from the beginning of visible damage to complete destruction of the damage indicator.
The original F-scale did not take these details into account. The original F-Scale historical data base will not change. An F5 tornado rated years ago is still an F5, but the wind speed associated with the tornado may have been somewhat less than previously estimated. Do tornadoes target mobile home parks? While it may appear tornadoes target mobile home parks, they actually do not. Mobile homes are, in general, much easier for a tornado to damage and destroy than well-built houses and office buildings. A mobile home, or manufactured home, by definition, is built at a factory and taken to the place they will occupy, so they are much more affordable than a house built on-site.
They are often built with lighter-weight materials, which do not hold up well in tornadic winds. Straight-line winds can also destroy a mobile home as easily as a tornado, especially one that is not anchored. Any wind gust that is sustained for 3 seconds over 50 mph can cause damage to mobile homes.
The problem of warning and sheltering mobile home residents has become the biggest obstacle to continuing to reduce death tolls from tornadoes. Do wider tornadoes cause more damage? There is a statistical trend toward wide tornadoes having higher EF-scale damage. This can be because of more strength or because of greater opportunity for targets to damage, or a combination of both. However, the size or shape of any particular tornado does not say anything conclusive about its strength.
Some small tornadoes can still do very violent damage of EF4 or EF5. And, some very large tornadoes over a quarter-mile wide have produced only weak damage. What is the difference between a tornado and a cyclone?

A tornado is a small-scale cyclonic circulation, and in the past, has been referred to as a cyclone. The term cyclone was used to describe anything that rotated counterclockwise, so often tornado a small-scale cyclonic circulation and cyclone were interchangeable. However, people still use it both ways. Are there electromagnetic or magnetohydrodynamic explanations for the development of tornadoes? As far as scientists understand, tornadoes are formed and sustained by a purely thermodynamic process. As a result, their research efforts are towards that end. They have spent a lot of time modeling the formation of a tornado and measuring many parameters in and around a tornado when it is forming and going through its life cycle.
They have not seen any evidence to support magnetism or electricity playing a role. Can my TV signal detect tornadoes? The idea was to be able to use your TV as a lightning detector to detect the radio waves emitted by a lightning flash, with the assumption that tornadic thunderstorms were very active lightning producers. But, not all tornadic storms produce large amounts of lightning. Also, TVs are all different and have different sensitivities, and some are even made to filter out lightning signals. Plus, if you are connected to cable, it won't work. The method was found to be completely unreliable and it has mostly been abandoned.
