Tornadoes

If your no about hurricanes typhoons and cyclones they are basically the same thing. Hurricanes begin as tropical storms over the warm moist waters like Atlantic and Pacific Oceans near the equator. As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere. The winds begin to circle counterclockwise north of the equator or clockwise south of the equator. The reatively peaceful center of the hurricane is called the eye. Around this center winds move at speeds 74 - 200 miles per hour. As long as the hurricane remains over waters of 79F or warmer, it continues to pull moisture from the surface and grow in size and force. When a hurricane crosses land or cooler waters, it loses its source of power, and its wind gradually slow until they are no longer of hurricane force--less than 74 miles per hour.

The Tri-State tornado killed 71 people in Indiana

The intensity of tornadoes is measured on the Fujita-Pearson Tornado Intensity Scale, or "F-Scale". This scale was named after the men who developed it, Dr. Theodore Fujita, and Allan Pearson, head of the Forecast Center in Kansas City. It ranges from F0 for the weakest tornado to F5 for the strongest.

In 2007 the National Weather Service in the U.S. upgraded to the Enhanced Fujita Scale, with the intention of providing more detailed and accurate ratings, which includes adjusted wind speed estimates. Overall, though, the damage done by each intensity category remains largely the same. Similar to the original scale, it ranges from EF0 to EF5.

The U.K. utilizes the TORRO scale, which uses similar damage and wind ranges to the Fujita-Pearson scale, but has two levels for every one on the F-scale, ranging from T0 to T11.

Tornadoes most often form along a cold front.

There are different standards of assessing that. Note that even "weak" tornadoes produce very strong winds that can cause damage. The strength of tornadoes is assessed on the Enhanced Fujita Scale from EF0 at the weakest to EF5 at the strongest (formerly the Fujita scale, F0 to F5). By some standards a strong tornado is one rated EF2 or higher, while by others it is one rated EF3 or higher. Another standard splits the scale into three parts with EF0 and EF1 labeled "weak" EF2 and EF3 labeled "strong" and EF4 and EF5 labeled "violent."

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.

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.

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.

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.

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.

There were 126 tornado fatalities in 2008.

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.

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.

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.

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.

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.

The infamous 1979 Wichita Falls tornado was an F4.

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.

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.

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!

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

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.
