Tornadoes
A tornado or twister is a violent, rotating column of air which typically has a speed ranging from 177 km/h to over 480 km/h. This devastating windstorm is usually characterized by its funnel-shaped cloud that extends toward the ground.

What is the common death rate of tornado?
The common death rate in a tornado is zero. 98% of tornadoes do not kill. In the majority of tornadoes that do kill,, the death toll is one. The higher the death toll, the less often it occurs.
What will happen if a tornado and a hurricane combined?
A tornado and a hurricane cannot "combine" as they operate on different scales. It is fairly common for tornadoes to produce tornadoes.
Has Colorado had any F5 tornado?
No. There has never been an F5 tornado recorded in Colorado. It has had a handful of F4 tornadoes.
How do people die because of tornadoes?
People can die in tornadoes from traumatic injuries caused by flying debris, structural collapses, or being thrown by the force of the wind. Additionally, the impact of a tornado can lead to drowning if people are caught in floodwaters. Injuries sustained during tornadoes can range from minor to fatal, depending on the severity of the storm and the level of preparedness and shelter available.
Where did the most violent tornado happen ever in August occur?
The most violent tornado and only F5 tornado recorded in the month of August struck Plainfield, Illinois, southwest of Chicago, on August 28, 1990.
How can we solve the tornado problem?
You can't, tornadoes are a feature of nature and a fact of life. If you are worried, either move location to where tornadoes are less common or build yourself a suitable tornado shelter and ensure your insurance covers you, your belongings and house.
Has Nashville Tennessee had a hurricane or tornado?
Nashville, Tennessee has had tornadoes, but it is too far inland to get hurricanes.
What are 3 things that causes a volcano a tornado a typhoon a hurricane and an earthquake?
Aside from hurricanes and typhoons, which are essentially the same thing, all of these have different causes. Here is each phenomenon simplified down to three causal factors.
Hurricanes/typhoons:
- Warm ocean water to power the storm
- Earth's rotation to set the storm spinning
- A disturbance to act as a "seed"
Tornadoes:
- Thunderstorms fueled by unstable air
- Wind shear to set storms spinning
- A downdraft to torn the rotation into a tornado
Volcanic eruptions:
- A source of magma (plate boundary or hot spot)
- A pathway to the surface
- Pressure from overlying rocks and trapped gasses
Earthquakes:
- Movement in the Earth's crust to create stress
- A fault for that stress to act upon
- Slipping of rock on either side of the fault
What time did the super Tuesday tornado start?
There was no "Super Tuesday tornado." The event was actually an outbreak of 87 tornadoes. The first tornado of the outbreak was an EF1 that touched down south of Hamburg, Arkansas at 3:26 PM Central Standard Time on February 5, 2008.
Is it very likely that a tornado will occur in Indiana in the month of February?
1) Indiana lies in a tornado-prone region.
+
2) Weather is unpredictable.
+
3) Tornadoes can occur in ALL 12 months of the year.
=
YES, it is QUITE likely that one or more tornadoes will visit Indiana in February of ANY given year.
Tornadoes do occur in Indiana in February, though they are rather rare at that time of year, and it is inevitable that it will happen again.
What is the density inside a tornado?
Air density inside a tornado is about 5-10% less than that of the air surrounding it.
Within a low-pressure system the probability of precipitation is high because the air is generally?
Within a low-pressure system, the air is rising and cooling, leading to the condensation of water vapor into clouds and eventually precipitation. This process is driven by the low pressure causing air parcels to rise and cool, increasing the likelihood of precipitation.
The term "mini tornado" does not have an exact definition. It has been applied to a number of different phenomena. Some people have called small whirlwinds such as dust devils mini tornadoes. Such whirlwinds are not actual tornadoes but may superficially resemble them.
News outlets in Australia and Europe may sometimes refer to the tornadoes they get as "mini tornadoes," even in instances of large, significant tornadoes. They equivocate like this because they are reluctant to admit that tornadoes occur in those areas.
People may occasionally call small, weak tornadoes mini tornadoes.
What does it mean when fast moving clouds are during a thunderstorm and tornado warning?
If a siren goes off or a tornado warning is issued, it means that either an actual tornado has been spotted, or that the dopplar radar has detected rotation within the thunderstorm, meaning a tornado can form at any time. Usually the weather channel or the emergency braodcast system will tell you on the screen if there is rotation or an actual tornado.
This is a good question, and one that needs to be addressed because this is a frequent sighting in strong thunderstorms. What you are seeing is simply the parent thunderstorm intaking air from all sides at the surface, where it rises up and continues to feed the storm. This updraft can support very strong winds and large hail, but it does not necessarily portend a tornado.
Furthermore, the clouds that are moving rapidly have nothing to do with a tornado (unless they're actually rotating, which is an indication of a funnel cloud or wall cloud, which precedes it). The air near the base of the main cloud deck is pretty saturated, and due to turbulent motions there are areas where these small clouds will form in the wind where the air saturates and condenses.
As mentioned above, if there is a tornado warning then there has either been a tornado spotted or there is a strong indication that one is forming or is on the ground. Be on the lookout for rotating clouds that are lowering from the base of the cloud deck. There are a lot of fascinating dynamics that occur with supercells and other strong storms that can spawn a tornado, and some of their manifestations are sometimes mistaken for a developing tornado. Keep an eye on the sky and watch for rotation, and remember that tornadoes more often than not do not develop even when the conditions are right. Even when a funnel clouds forms, it only reaches the ground about half the time.
Why are trailer parks tornado magnets?
Trailer parks do not attract tornadoes. This is a misconception created by the fact that tornadoes rated F1 and F2 tornado can destroy a trailer but usually not a house. To destroy a house of standard or above standard construction would normally take an F3 or stronger tornado, tornadoes this strong are not as common as F1 and F2 tornadoes. Because a tornado does not have to be particularly intense to cause catestrophic damage to a trailer park, a tornado that strikes one is more likely to recieve media coverage.
Overall scientists do not believe that there is an increase in the occurrence of most natural disasters. However, due to technological advancements we are increasingly aware of them when they do happen.
What time of the year are tornadoes and hurricanes most likely to form?
Hurricanes are most common in summer and early fall. Tornadoes are most common in spring and early summer.
A "major hurricane" is a hurricane rated as a 3-5 on the Saffir-Simpson scaleor, in other words, has sustained winds of at least 111 mph.
The Saffir-Simpson scale goes from category 1 to category 5.
See Web Links for more information on the Saffir-Simpson scale
What weather devices can detect the threat of a tornado?
The main tool is Doppler radar, which can remotely measure wind speed and direction. This can be used to find rotation in a storm associate with a possible tornado. Another, recently developed tool is dual-polarized radar. Unlike conventional radar, this radar can distinguish between rain, hail, and tornadic debris.
How are tornadoes and thunderstorms related?
Tornadoes are usually produced by extremely strong thunderstorms. A thunderstorm is created by rapidly rising air. This air causes a low pressure area on the ground. If the storm encounters strong wind shear it can start a counter-clockwise (in the northern hemisphere) vortex in this updraft called a mesocyclone. Further development can cause the mesocyclone to tighten and intensify into a tornado.
