Tornadoes

Tornadoes do not intentionally move towards each other. However, in rare cases where two rotating updrafts occur in close proximity, they may converge and create a larger tornado or intensify each other.

The original scale for rating tornadoes is officially the Fujita-Pearson scale, though the Pearson numbers were rarely used. The scale is normally referred to simply as the Fujita scale. In 2007 the United States stopped using this scale in favor of the Enhanced Fujita scale.

No. a typical tornado moves between 25 and 40 mph. Winds in a tornado are faster, however. Some tornadoes can produce winds in excess of 300 mph, but only within a small portion of the tornado and no single location would experience such winds for more than a few seconds. The rest of the tornado will produce significantly slower, though still very strong winds. Tornadoes this strong are very rare however. Most tornadoes have peak winds of less than 110 mph.

Tornadoes pick up objects by creating a strong rotating column of air that moves upwards and spins rapidly. The fast wind speeds within the tornado can lift and carry objects like debris, trees, and vehicles with significant force. The intensity of a tornado's winds and the size of the objects determine what it can pick up and carry.

Not really. The winds of a tornado carry an enormous amount of force, but the tornado itself is composed almost entirely of air.

The winds of a tornado carry a large amount of force. Most tornadoes are capable of toppling trees and breaking tree limbs, some of which may fall on power lines, snapping them. An EF1 or EF2 (86-135 mph winds) carries enough force in its winds to topple and snap wooden power poles. The winds of an EF3 tornado (136-165 mph) are powerful enough to crumple steel transmission towers.

There are not fronts in a tornado. However, the thunderstorms that produce tornadoes are most often found ahead of clod fronts. Dry lines are also common producers of tornadoes. Warm fronts and stationary fronts less often. Some tornadoes form from storms not associated with any fronts.

Neither. The sound they refer to is the general rumble or roar of the train going down the tracks. The "chug chug" is characteristic of steam steam trains which are rarely used nowadays.

Yes. Houses have been move by tornadoes. However, in most cases the house does not make it out intact.

Florida is in such a position that sea breezes from the Atlantic Ocean and the Gulf of Mexico converge. The converging warm, moist air rises and forms thunderstorms, which may spawn tornadoes. Subtropical storm systems and the southern ends of extratropical storm systems often trigger thunderstorms which are then fueled by the plentiful warm, moist air.

An Earthquake can be far deadlier.

Fore example the Earthquake in Haiti killed over had a death toll over 200,000.

The deadliest tornado in world history (in Bangladesh) killed about 1,300.

Earthquakes when properly prepared for however can be far less damaging than the one in Haiti. Tornados can be far deadlier however, because they cannot be predicted and their paths are random.

No, not a real tornado. Tornadoes can be simulated on supercomputers, and vortices can be created in the lab. The latter example does provide insights into vortex mechanics, but their applications in processes specifically relating to tornadoes are limited.

High pressure systems can inhibit tornado formation by creating stable atmospheric conditions that suppress the development of thunderstorms, which are a necessary ingredient for tornadoes. When high pressure dominates an area, it can limit the availability of moisture and wind shear needed to fuel tornado activity. However, high pressure can also sometimes enhance tornado potential by creating strong boundaries with low pressure systems, leading to favorable conditions for tornado formation along these boundaries.

There is no exact temperature. especially since many tornadoes form in storm generate by cold fronts where the temperature changes fairly quickly. However they generally require warm temperatures and rarely form in temperatures of less than 60 degrees Fahrenheit.

The strongest winds in a tornado can reach speeds of over 300 mph (480 km/h), typically found in the most destructive tornadoes known as EF5 tornadoes. These extremely high winds can cause significant damage to structures and landscapes in their path.

Isotopes can be used as tags by incorporating them into molecules or compounds that are then added to a sample of interest. The presence and abundance of the isotope can be detected using specialized techniques like mass spectrometry, allowing researchers to track the movement or behavior of the tagged molecules within the sample. This is commonly used in biological, environmental, and chemical research.

It varies depending on the structure and the intensity of a tornado. In most cases, though, it takes a matter of seconds, which is usually how long a structure is exposed to the strongest winds. One analysis of the fast-moving EF5 tornado that hit Smithville, Mississippi tornado of 2011 found that houses wiped clean off their foundations were exposed to the strongest winds of the tornado for less than 3 seconds.

The main component is the extremely powerful wind present in a tornado. These winds carry an enormous amount of force that can tear away parts of a structure, sometimes causing it to collapse. In other cases the froce of the winds may push a structure over or even blow it away. In some cases structures even go airborne. Additionally, the winds carry debris which can cause damage upon impact. In some cases objects carried by the winds may be the size of cars, or even larger. One house was destroyed after a tornado blew a mobile home into it.

Yes, it is possible for a tornado to propel a thin piece of straw through a tree trunk. Tornadoes can generate extremely strong winds that have enough force to cause objects to be driven through other objects.

Tornadoes in the U.S. are currently classified on the Enhanced Fujita Scale.

Tornadoes are powerful storms, but they cannot pick up or carry heavy objects like cars or houses. The strongest tornadoes may be able to lift and carry smaller debris like tree branches or roof shingles, but they typically cannot carry heavy objects due to their erratic and turbulent nature.

There is much difference between a hurricane and a monsoon. The primary difference is that a hurricane is a storm whereas a monsoon is a seasonal wind. Furthermore, monsoons are cyclic. Hurricanes are non-cyclic.

Out of the ground, no. However, a strong enough tornado can wipe a house from its foundation. Normally this will earn a tornado a rating of EF4 or EF5, though if the house is poorly anchored an EF3 rating may be appropriate.

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.

Yes. It is called the Enhanced Fujita scale. By its parameters damage is used to estimate wind speed, which is in turn used to assign a rating ranging for EF0 for the weakest tornadoes to EF5 for the strongest.
