Tornado's 5 interesting how much do you know about them? Read and share.

1) Tornado:  Moving in a circular pattern, and having a wind speed (in most cases) of under 110 miles per hour (180km) in contact with the earth on the lower end and a cumulonimbus cloud on the upper. In the most extreme of cases, Tornado's can reach speeds of more than 300 miles per hour (480km), exceeds 2 miles (3km) in diameter Rotating clockwise (northern hemisphere) and counter clockwise (southern hemisphere) staying on the ground sometimes for great distances.

I would not chase this, but then of course I wouldn't know what I was doing
either, I do have a deep respect for tornado's however. 

  I have seen the sky turn "green" shortly prior to loud thunderclaps then driving hard rain, looking skyward we would watch the Cumulus clouds at the bottom for "tails" dipping down. Watching the spinning cloud in its funnel shape heading earthward, we knew a tornado was forming, then we headed for the basement. We were taking shelter one day when a tornado hit a tree in the yard, breaking a huge branch causing it to fall across a power line. In the basement we watched the electrical panel stripped of its wires as the tornado ate the wiring like spaghetti, luckily all was OK, except the electrical system.

Trees and Cars offer very  little resistance to Tornadoes 

  The multiple vortex tornado, suction vortices, landspout, and waterspout are three types of storms very closely related to tornadoes.
  2) Waterspout tornado:  Connected to a large cumulus or cumulonimbus cloud this tornado shaped wind current, funnel shaped, normally a non-supercell entity forming over a body of water. They are not classified as a "true" tornado, they develop in the sub tropics being rare in the higher latitudes. They either form over water, staying over the water until they dissipate or move onto land becoming a "land tornado". At sea waterspouts are normally accompanied by high winds and heavy seas, large hail and extreme dangerous lightning and severe thunderstorms are common companions, having the same properties of land tornadoes. These are tornadoes on the water, to put it simply, the dynamic properties of the ocean make these storms and cyclones very unpredictable.
   3)  Multiple-Vortex-Tornado: Containing several vortexes of the wind, referred to as "subvortices or suction vorices", the vortex wind rotates inside of the main funnel vortex. The subvortices are sometimes visible when the tornado is forming, otherwise, they go undetected, or when debris and moisture (in the form of condensation) are in equal balance is when the wind vortex is not obscured. They have the ability to increase wind speed to well over 100 miles per hour at ground level. The Multiple-Vortex-Tornado is often the cause of extreme damage which occurs right next to much lesser damage laying in the tornado's path. May 31, 2013, the largest tornado ever recorded was a Multiple-Vortex-Tornado, striking El Reno, Oklahoma. Three researchers were killed, Tim Samaras, his son Paul and their partner Richard Henderson. It was at its maximum 300 miles per hour (>476 km/h) and >2 1/2 miles at the base (4.2km). It was rated at EF3 on the Fujita scale due to a lack of property damage.
  4)  Suction vortices: Sometimes referred to as "suction spots" are common as "substructures" of many Tornado's, they are not always easily visible, occurring at the base of a tornado on the ground level. This substructure of a Multiple-Vortex-Tornado is not restricted to occurring only at the base of Tornado's they also appear as "dust devils" being a natural result of vortex wind dynamics.
  5)  Landspout: Not related to a thunderstorm tornado, the term was first used by Howard Bluestein in 1985. An expression to describe tornadoes forming with the main cloud in its forming stage, the vortex originates in the outer boundary layer. The landspout received its name due to the similarity of its appearance to a "waterspout".

Landspout, I've never seen one, have you? It looks like an odd duck.

  Smaller and weaker than super cell Tornado's they do not form with a pre-existing rotation in the mother cloud which forms the landspout by pulling and stretching the outer wind vortex up and into the cumulus congestus's cloud's upward suction. Doppler radar rarely is able to detect them, making tracking extremely difficult. The debris whirling around a landspout is often the only way to detect them, however, they are still considered Tornadoes. They occur mainly in the high plains regions of the United States, May through September. Most cause minimal damage and to exist for a period longer than 15 minutes is unusual however not unknown.
  Summary: Tornadoes are highly unpredictable  entities, the many different types make the prediction of movement, creation, duration and dynamic properties difficult to predict. They can start out strong and end shortly and weak, or conversely start weak and gain in all areas becoming stronger and more unpredictable. To me they are nothing to mess with, I heard stories while growing up in the northernmost reaches of "tornado alley" that encouraged respect for these extremely powerful and unpredictable weather compatriots of ours. They do occur most places of the world, however, no area being more afflicted than the United States Great Plains, Tornado Alley.
