Tornadoes&Twisters- The main types

A tornado is a violent, rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of acumulus cloud. Tornadoes come in many shapes and sizes, but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Most tornadoes have wind speeds less than 110 miles per hour (177 km/h), are approximately 250 feet (80 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme can attain wind speeds of more than 300 mph (480 km/h), stretch more than two miles (3 km) across, and stay on the ground for dozens of miles (more than 100 km). Various types of tornadoes include the landspout, multiple vortex tornado, and waterspout. Waterspouts have similar characteristics to tornadoes, characterized by a spiraling funnel-shaped wind current that forms over a body of water, connecting to a large cumulus or cumulonimbus cloud. Waterspouts are generally classified as non-supercellular tornadoes that develop over bodies of water. These spiraling columns of air frequently develop in tropical areas close to the equator, and are less common at high latitudes. Other tornado-like phenomena which exist in nature include the gustnado, dust devil, fire whirls, and steam devil. There are several different scales for rating the strength of tornadoes. The Fujita scale rates tornadoes by damage caused, and has been replaced in some countries by the updated Enhanced Fujita Scale. An F0 or EF0 tornado, the weakest category, damages trees, but not substantial structures. An F5 or EF5 tornado, the strongest category, rips buildings off their foundations and can deform large skyscrapers. The similar TORRO scale ranges from a T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes. Doppler radar data, photogrammetry, and ground swirl patterns (cycloidal marks) may also be analyzed to determine intensity and assign a rating.

i am noticing a lot of wrong information on this video

[Jeanng11nov71]

@sqlru31 Please explain where the informations are wrong, in the video or in the description and give a few examples of what you have considered wrong informations and, if possible, the sources of the bases of your conclusions. Incidentally, are you an expert on tornadoes?

[derbeh]

I noticed a few erroneous bits of information. One, the video purporting to show multiple vortices was showing a satellite tornado and the vid showing the satellite tornado was actually showing a multiple vortex tornado.

tornadoes have both interested me and scared me...i blame the wizard of oz for that. I like this video. thanks for posting :D

D*mn I would hate to be stuck in a fire tornado

oklahoma gets the wite mouth monster

@DramaticMoments That......is a damn good question. I would suppose that it would....depending how concentrated the waterspout's base is a the point of contact with the water....and how long that waterspout base stayed in one place on the water. Very interesting.

@IxenBlaze You are correct, they had the info totally wrong with the video showing the so-called "multi-vortex" tornado.

@Vamp6661 Oh God Yes. I'm an experienced chaser and have seen F-2's do major damage. Unless a person has seen a tornado up close and in person.....you cannot imagine just how huge a F-2 tornado is. Once you do it's easy to understand just how powerful these are. Even an F-1 can scare you to death, and yes, they are more than capable in killing you quickly. Don't let Hollywood or t.v. shows impair your thoughts on the smaller tornadoes.

@Jeanng11nov71

Not sure what anyone else found, but the description of a multiple vortex tornado in the video is slightly misleading. A multiple vortex tornado is not multiple tornadoes within the same supercell, but multiple vortices within the tornado itself. The central vortex in one becomes unstable near the ground so the main funnel has to branch off while following the same column of air.

the fire tornado was awesome
