Is tornado alley safe against the most powerful tornadoes?

Not really, tornado alley is one of the areas most frequented by the strongest tornadoes, rated EF4 and EF5.

However, even in tornado alley you are unlikely to be hit by such a strong tornado.

How much area does a tornado take up?

The area affected by a tornado can vary widely, but on average, the diameter of a tornado is about 150-500 meters (500-1,600 feet). However, larger tornadoes can have a path that is several kilometers wide.

What happens if tornado's collide?

If two Tornadoes collide, two things could happen. One, they could whipeout or destroy each other (in other words, stop turning.) Two, they could from an even more destructive torndoes by forming together.

Can you hide in a crawl space from a tornado?

It depends on where the crawl space is. If it is under the house or in the foundation it may be a good place to go. If it is a space just under the roof then it would be one of the worst possible places to go. When a tornado hits a house the roof is usually the first thing to go, which may either exposed the crawlspace or take the crawlspace with it.

Do tornadoes spin clock wise or counter clock wise?

It depends what hemisphere your in. If your in the northern hemisphere, 999 out of a 1,000 Tornadoes will spin counter clock wise. In the southern hemisphere 999 out of a 1,000 with spin clock wise. BUT that doesn't mean you will never see a clock or counter clock wise tornado in the same hemispheres. If you get a counter clock wise or clock wise tornado in the opposite hemispheres (which would be rare or... EXTREMELY rare! Which would be 1% of the spin cycle) the normal one will be coupled with the non normal one.

What causes tornadoes to form in tornado alley?

The formation of tornadoes is complicated.

First, a condition called wind shear, in which the speed or direction of the wind changes with altitude. If the shear is strong enough it can essentially tilt a thunderstorm, this separates the updraft and downdraft of the thunderstorm, preventing them from interfering with one another. This allows the storm to become stronger and last longer.

Additionally, if the wind shear is strong enough it can start the air rolling in what is called horizontal vorticity. This horizontal vorticity can then be turned vertical by a thunderstorm's updraft. When this happens, the thunderstorm may start rotating. The rotation is especially strong in an updraft called a mesocyclone. If the storm intensifies rapidly enough, a relatively warm downdraft called a rear-flank downdraft or RFD can wrap around the bottom part of the mesocyclone. This can then tighten and intensify its rotation and bring it down to the ground to produce a tornado.

The thunderstorms in Tornado Alley typically form when warm moist air from the Gulf of Mexico collides with cool air from Canada and dry air from the Rockies. This forces the warm moist air, which is less dense, upwards, causing the moisture in it to condense and form thunderstorms.

When is tornado season in Ohio?

Tornado season in Ohio typically occurs from April to July, with peak activity in May and June. The state experiences an average of 19 tornadoes per year. Residents should stay informed about weather warnings and have a plan in place to seek shelter if necessary.

What is an intense thunderstorm that can spawn tornadoes called?

A supercell thunderstorm is a highly organized and powerful type of thunderstorm that can produce intense winds, large hail, heavy rainfall, and tornadoes. These storms are characterized by a rotating updraft called a mesocyclone, which can sometimes lead to the development of tornadoes.

Why is the bathtub a safe place for a tornado?

A standard porcelain bathtub is very heavy which makes it an unlikely candidate to be swept away. Most baths are installed very securely as they must support the weight of dozens of gallons of water. Should a structural collapse occur, the tub will act like a coffin, burying you alive :)

Revision 2/7/2012:

Please note, however, that most bathtubs are no longer made of porcelain. Instead, they are made of lightweight fiberglass, which would provide very limited protection during a tornado. Additionally, if winds are strong enough, even a porcelain tub won't offer protection, as you (and the tub) can easily be picked up by the storm. Go underground to be safe.

Do tornadoes only go counter clockwise?

No, most tornadoes in the southern hemisphere rotate clockwise.

Additionally, some tornadoes, called anticyclonic tornadoes, rotate clockwise in the northern hemisphere. Fewer than 1% of tornadoes are anticyclonic.

Do you get tornadoes in England?

Yes, tornadoes are rare in England compared to other parts of the world, but they can and do occur. They are typically much weaker than tornadoes seen in the United States, and tend to cause less damage. England's relatively milder climate and landscape make it less prone to frequent and severe tornado activity.

What kind of damage happens during a tornado?

there are 6 different types of damage in a tornado

  1. EF0 minor to no damage
  2. EF1 moderate damage
  3. EF2 considerable damage
  4. EF3 severe damage
  5. EF4 devastating damage
  6. EF5 incredible damage

What was the Wichita falls tornado rating?

The infamous 1979 Wichita Falls tornado was an F4.

Do tornadoes always come from a wall cloud?

No, tornadoes can occur without a visible wall cloud. While a wall cloud can be a precursor to tornado formation, tornadoes can also develop from other types of storm clouds or even from the cloud base itself.

How are tornadoes constructive?

Natural tornadoes are not constructive. They cause damage and kill people, so they are destructive; however, there are people who believe stationary "tornadoes" can be created and used for a source of power. If it is possible, those man-made "tornadoes" would be constructive by providing inexpensive power.

How do you describe a thunderstorm?

a thunder can get a lot of energy. when you get near to a thunder you can die for the shock they also take out your lights in your house.

A thunder storm is frightening, raging, dangerous, windy,when a lightening bolt comes down its like the sky is split in two! Tempest, Ra-gin skies, violet clouds, flashes of light!

How many town did the tristate tornado hit in 1925?

It hit nine towns and the only one I remember the name of was Gorham which was completely destroyed by the tornado.

What places are more prone to tornadoes?

Tornadoes are most common in the central United States, often referred to as "Tornado Alley," which includes parts of Texas, Oklahoma, Kansas, Nebraska, and South Dakota. However, tornadoes can occur in many other regions of the world, including Australia, Argentina, and parts of Europe. Areas with favorable atmospheric conditions, such as warm, moist air colliding with cool, dry air, are more prone to tornadoes.

How do you run a way from tornado?

If you are outdoors and cannot seek shelter, the best option is to find the lowest lying area such as a ditch and lie flat, covering your head. If you are in a vehicle, try to drive at right angles to the tornado's path to get out of its way. Always stay informed about tornado warnings and have a plan in place before an emergency situation occurs.

Will cold or hot water separate marker pigment from filter paper?

Hot water is more effective in separating marker pigment from filter paper as it helps to dissolve and lift the pigment more easily compared to cold water. However, it is important to consider the type of marker and paper used, as some markers may have pigments that are more soluble in cold water.

What type of fronts are associated with tornadoes?

Tornadoes form in areas where both thunderstorms are present and wind speeds and directions change with height. You do not necessarily have to have a front present for a tornado to occur, however frontal boundaries often increase the amount of lifting to help develop thunderstorms and can serve to increase changes in with direction with height, all of which can increase the threat of tornadoes. The main type of front that increases the risk of tornadoes is called a dry line. Cold fronts and sometimes warm fronts can increase tornado risks and occasionally a sea-breeze front can cause a slight increase in tornado potential over a small, localized area.

Why Florida does not have violent tornadoes?

Florida has actually had two violent F4 tornadoes in the past 60 years, but the reason such strong tornadoes are so rare has to do with the climate.

Tornadoes form in very strong thunderstorms called supercells, which form best near boundaries with large contrasts in temperature and/or moisture content. In Florida, which is nearly tropical, the temperature contrasts tend to be small, and so the storms are generally not intense enough to produce strong tornadoes.

How many different tornadoes are there?

There are different types of tornadoes based on their size, strength, and formation. The most common classification system for tornadoes is the Enhanced Fujita (EF) scale, which ranges from EF0 to EF5 based on the tornado's estimated wind speeds and damage potential.
