Tornadoes

There were no recorded tornadoes in Ohio in 1988.

A "tornado" of fire is called a firewhirl, but these are not true tornadoes.

Since official record keeping began in 1950, there have been 58,009 tornadoes recorded in the U.S. The actual number of tornadoes is likely much higher though, as in the early part of this period we missed many of the weaker tornadoes.

Modern records suggest the U.S. averages between 1,200 and 1,300 tornadoes per year. This suggests that more than 75,000 tornadoes ocurred in this time period, and likely more than 80,000.

There are a few major issues. First, it is very difficult to get wind measurments from within a tornado, especially at ground level. Damage is used as a proxy for wind speed. As a result, tornadoes that don't hit much are difficult to rate. Third, we are not exactly sure how well our wind estimates correspond with damage.

The central region of a tornado where winds move in a circular pattern rather than an inward spiral is called the core. Some tornadoes will develop a strcutures that has been called an eye due to its similarity to the eye of a hurricane.

Yes. Tornadoes occur every year. The 1920s was the deadliest decade for tornadoes in U.S. history. Among these is the Tri-State tornado, the deadliest tornado in U.S. history, which killed 695 people. In addition to this, there were several tornado outbreaks in 1920 and 1927 with death tolls over 200, with one death toll possibly approaching 400.

No. Illinois is not in Tornado Alley, however it is still prone to tornadoes.

The energy for all weather on Earth ultimately comes from the sun. The sun's energy heats the surface of the Earth, which in turn heats the air just above it. Where the sun heats the surface of the ocean, evaporation occurs, which moistens the air. Warm, moist air carries a very large amount of energy that is the power source for thunderstorms. Thunderstorms are what spawn tornadoes, but not just any thunderstorms. The thunderstorms that spawn tornado typically form along a frontal boundary. Given the right setup of wind patterns at different levels of the atmosphere, these storms can start rotating, turning into supercells. The rotation in the storms can then tighten and intensify to form tornadoes.

So, in short, the sun heating the Earth and causing evaporation provides energy that powers thunderstorms. Under the right conditions these storms can start roatating, and their energy can become focused in the form oftornadoes.

Tornadoes can damage and destroy people's property, including homes and businesses. In the worst cases whole towns and neighborhoods may be completely destroyed. People may be killed or injured and may suffer significant financial burder from the damage, especially if they are unuinsured or underinsured.

No. Tornadoes do not have names.

This is based on the old and now disproven idea that the low pressure inside a tornado caused buildings to explode. The idea holds that as a tornado passes over, the pressure outside drops radily, while pressure remains high inside the building, and that opening windows would relieve this pressure difference.

This idea has been disproven, and officials now advise against opening windows during a tornado. There are several reasons for this.

First, the pressure drop inside a tornado is not large enough to inflict any significant damage on a stroncutre. Second, buildings are not airtight, and pressure will equalize fairly quickly. If a tornado is strong enough to cause significant damage, the windows will likely break anyway Tornadoes cause damage through wind and debris, not through pressure drop. It has actually been shown that if the tornado is weak enough that windows remain intact, or if the worst of the tornado misses, opening windows allows wind to enter the building and cause damage on the inside. Additionally, opening windows wastes precious time that should be spent getting to a safe place.

In the South, tornadoes are most often associated with a cold front, though in Texas they may form along a dry line. In some cases, though, the tornadoes may form without a front. For example, landfalling hurricanes, which are not associated with fronts, often spawn tornadoes.

Technically, there is no such thing as an underwater tornado. By definition a tornado is a violently rotating column of air. A vortex underwater is called a whirlpool. Whirlpools are not like tornadoes, however. They are not nearly as violent and are usually harmless, though some stronger whirlpools can pose a threat to swimmers and small boats. Natural whirlpools can be observed in streams and at some tidal inlets.

The first documented tornado in North America was recorded on July 31, 1643, in Cambridge, Massachusetts. This early account was made by John Winthrop, the governor of the Massachusetts Bay Colony, who described the tornado's path and effects. While there were likely tornadoes before this event, Winthrop's record is one of the earliest written descriptions we have.

Tornadoes can cause significant destruction to the natural environment by uprooting trees, damaging vegetation, and altering landscapes. The intense winds can strip away topsoil, leading to erosion and negatively affecting local ecosystems. Additionally, the debris and destruction can disrupt habitats, displace wildlife, and affect the overall health of the affected area, potentially leading to long-term ecological changes.

The United States averages about 1,250 tornadoes per year, which works out to an average of 104 tornadoes per month. However, the average number of tornadoes is not the same for each month. The months are as follows.

January: 36

February: 32

March: 83

April: 184

May: 270

June: 233

July: 128

August: 80

September: 71

October: 58

November: 55

December: 25

Note that in any given year activity may deviate significantly from the average For example, the record for most tornadoes in one month is 757, set in April 2011.

Tornadogenesis is the process by which tornadoes form.

The 1840 Natchez tornado killed at least 317 people and injured another 109.

If there is a tornado watch what you have to remember is that it does not mean there is an imminent threat of tornadoes. Even when you area is under a tornado watch, your chances of actually having a tornado are still quite small.

A tornado is a vortex and may also contain vortices. A vortex is a rotating body of liquid or gass. In a tornado, the vortex is made visible by condensation or dust and debris. It may look like a cone, tapering appendage, or column attatched to the clouds, or may take the appearance of a tube or swirling mass of dust.

Except in the most violent tornadoes, structures generally are not blown away unless they are weak or poorly anchored, though they may still be destroyed. Banks are generally very sturdy structures. To blow a bank away would require a tornado of EF5 intensity, the highest rating possible. Tornadoes this strong are very rare. Since the new scale went into effect in 2007, 9 tornadoes have been rated EF5. Three of those tornadoes struck banks, and only one of those banks was hit by the full force of the tornado.

The first case was in Parkersburg, Iowa on May 25, 2008. The worst part of the tornado missed the bank, which was badly damaged, but remained standing.

The second case was in Joplin, Missouri on May 22, 2011. The bank was destroyed with all exterior walls swept away; only the vault remained in place.

The third case was in Moore, Oklahoma on May 20, 2013. The Federal Credit Union was demolished, with only the vault left intact.

The negative economic effects of a tornado are mostly local. When a major tornado strikes a city, the cost of damage and repairs can be enormous. There is also a cost of lost productivity as workplaces and businesses are destroyed or forced to close for repairs and as potentially hundreds are injured. Many people may not be willing to rebuild and will move elsewhere.

While there are some general things that happen while a tornado is approaching, a storm may not necessarily have these characteristics, as there is a great deal of variability in how a tornadic storm can behave.

Most tornadoes occur in the rear portions of thunderstorms. As a tornado is approaching you will often experience thunder, lightning, and very heavy rain. Hail, potentially very large, may also be present. In many cases before the tornado hits, the rain will stop, and there will be an eerie stillness. The sky may appear gray, black, green, or yellow. You may see the tornado itself, looking, perhaps, like an enormous elephant trunk or cone, or sometimes a whirling mass of dust and debris. The clouds around it may rapidly rotate. Sometimes, however, the rain does not stop, and the tornado is never seen, and then is suddenly upon you. Reports on the sound that people hear near a tornado vary. The classic description says that a tornado has a low roar like a freight train. Others have compared the sound to a jet engine or a waterfall. Still others have said that the sound was indescribable, unlike anything they had ever heard.

There is not real scientific evidence that animals predict tornadoes. Tornadoes come with thunderstorms, and some animals, such as dogs, may hear the thunder before we do, but it is unlikely that they can actually predict tornadoes.
