Tornadoes

We cannot stop tornadoes from occurring or from striking communities. It may be possible to reduce the damage done, however, by building structures to standards that allow them to withstand powerful winds. Even then, few structures can survive the strongest tornadoes.

There was a massive response first to find people, both living and dead. Federal and non-government agencies brought food and supplies to people. The people of Joplin themselves helped each other considerably in treating the injured and rebuilding.

Yes. Tornadoes can occur anywhere in Minnesota. Rochester has had several tornadoes. The most notable was an F5 that struck on August 21, 1883, killing 37 people.

Generally you should shelter in place during a tornado as you are more likely to survive if caught in your house than if caught in a car. Evacuating from a tornado is not as simple as it sounds, as the paths of tornadoes can be unpredictable and it is possible to get stuck in traffic since peak tornado activity often coincides with the evening rush hour. That said, if you are in a mobile home when a tornado is coming you should leave it for sturdier shelter.

Berwyn, PA can get tornadoes and thus tornado warnings. Answers.com cannot provide real-time information on tornado warnings. For that information you should go to the official website of the National Weather Service. For potential weather emergencies you should purchase a battery-powered weather radio.

The formation of tornadoes is complicated.

First, you need thunderstorms, then you need 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.

Thunderstorms and tornadoes, whether they are quick or not, are the product if cumulonimbus clouds.

Yes, in some instances one tornado may spawn a smaller satellite tornado.

They can. Trailers a not a well-built as most houses and so are more easily destroyed. That said, some weak tornadoes will damage trailers but leave them mostly intact.

Cumulonimbus clouds.

The safest place to be during a tornado is in a basement or storm cellar.

Tornadoes can lift houses by generating extremely low pressure inside the vortex, which creates suction force around and underneath the structure. This suction force can effectively lift the roof off the house or even cause the entire structure to be picked up and carried. Additionally, strong winds in the tornado can also push against the walls of the house, contributing to its lift.

This cannot be answered simply, as both hurricanes and tornadoes vary greatly in how bad they are. The impacts of both tornadoes and hurricanes can range from negligible to devastating. That said, the very worst hurricanes can be far deadlier and more destructive than the worst tornadoes.

No, in fact, they are much less powerful. ----- A waterspout is a tornado that forms over water instead of land. Unless you are on water, in its path, a tornado would be worse, because more people live on land.

Density is not a direct factor in the formation of tornadoes. Tornadoes form from the interaction of warm, moist air near the surface and cool, dry air aloft, creating instability in the atmosphere. Wind shear and other atmospheric conditions play a more significant role in tornado formation than density.

Global data is not available, but the US had 1075 recorded tornadoes in 2000.

In simple terms, only a thunderstorm can concentrate the energy needed to form a tornado. Most tornadoes from from a thunderstorm with a rotating updraft. Others develop from interactions between turbulence and a non-rotating updraft. Other varieties of whirlwind can develop without thunderstorms, but they are not nearly as strong as tornadoes.

A tornado can move in any direction, but the most common direction of travel is southwest to northeast. Southeast-moving tornadoes are not uncommon.

The world's deadliest tornado was the Daulatpu-Saturia tornado, which struck central Bangladesh on April 26, 1989. It killed an estimated 1,300 people.

The issue is not the amount of wind, but how the wind moves. A tornado consists of a violently rotating column of air produced by a thunderstorm. As a general rule the winds must be strong enough to cause damage, but there is no hard and fast lower limit.

Tornadoes can occur at any time of year, but are most common in spring and early summer. The general peak of tornado activity will vary by region.

The best thing that people can do is to pay attention to weather advisories so they can no when a tornado is coming. When a tornado threatens, people should get to some underground shelter or get to the interior part of a sturdy house or building.

Not all of the mechanism for how tornadoes produce sound are fully understood. That said, in just about any case, you can hear a strong wind, and tornadoes can produce the fastest winds on earth. If a tornado is hitting a community, part of the sound may be buildings and trees being destroyed.

The Tri State tornado was the deadliest, longest lived, fastest, and farthest traveling tornado in U.S. history. It killed 695 people, injured more tan 2,000 and destroyed more than 15,000 homes. It lasted for 3 hours and 29 minutes, traveling 219 miles. At times it moved at up to 73 mph. It was an F5 and maintained F4 to F5 intensity along nearly its entire path ranging in width between 3/4 mile and 1 mile. Part of its deadliness was due to a combination of its wide path and the low cloud base, which resulted in people not recognizing it as a tornado as it approached. It was hidden behind rain at times as well.

A tornado and a twister are actually the same weather phenomenon; both terms are used interchangeably to refer to a violent rotating column of air. The damage caused by a tornado or twister can be extensive and devastating due to its strong winds, which can result in destruction of buildings, uprooting of trees, and displacement of debris.
