Tornadoes

The Tri- state tornado was on the ground for about 3 and a half hours, or approximately 210 minutes.

No. Tornadoes can occur almost anywhere that gets thunderstorms.

Yes in every state. Not all states have violent tornadoes but all states have reported at least a few weak tornadoes, even Alaska and Hawaii.

March 18, 1925.

The Greensburg tornado was an EF5 on the Enhanced Fujita Scale, which is equivalent to an F5 on the original Fujita Scale.

Stay indoors, listen to the radio, take in loose objects that are outside, etc. But remember that even in a tornado watch, the odds that you actually get hit by a tornado are very low.

Kilbeggan Ireland in Europe April 30th 1054 was the first recorded tornado. But they have doubtless been going on since prehistoric times.

Minnesota averages about 45 tornadoes per year.

Yes. There have been 3 confirmed tornadoes in Noble country, Ohio since 1950 and most likely more tornadoes before 1950.

The first recorded tornado hit kilbeggan, Ireland on April 30th 1054.

However, there were no doubt many thousands of tornadoes that occurred before then that were never recorded. Tornadoes have most likely been occurring since Earth had an atmosphere.

The most recent confirmed tornado (as of August 26, 2011) was an F1 that damage trees near Kirkwall, Ontario on August 24. There have been unconfirmed reports of tornadoes in North Carolina associated with the outer bands of Hurricane Irene.

No. Mountains are not ideal for tornado formation, but they do not stop tornadoes. Higher elevations typically have cooler, drier, more stable air, which is not an ideal environment for tornado formation. However, tornadoes can form on mountains. In 2011, a tornado in Glade Spring, Virginia wrecked camp sites on Mt. Rogers at nearly 4,000 feet. An F4 tornado occurred at 10,000 feet in northwest Wyoming on July 21st, 1987. Events like these are uncommon but do occur.

Tornado Alley has a number of factors that lead to its high frequency of tornadoes.

First, it's prone to collisions of three different types of air mass: warm, moist air from the Gulf of Mexico, cool air from Canada, and dry air from the Rockies. Collisions of such air masses can produce very strong thunderstorms, which are needed for tornadoes to form. Another factor is wind shear. This tilts thunderstorms, which allows them to become stronger and last longer. Interactions with wind shear also gives thunderstorms the rotation they need to produce tornadoes.

A third factor is something called a cap, which is a layer of stable air that forms a few thousand feet off the ground. This cap usually prevents thunderstorms from developing, however, storms sometimes punch through or break this cap. Storms that do this develop explosively and can become extremely intense.

The eye of a tornado itself most likely does not do damage as radar analysis and eyewitness testimony show that they eye of a tornado is calm like the eye of a hurricane. The wind and debris surrounding the eye is what causes damage.

The average tornado has a height of about 660 feet (200 meters), although they can range in height from tens of feet to over a mile depending on the strength and intensity of the tornado.

Usually. If you see rotation in the clouds it means a tornado may form. If you see a cone, cyclinder, or "elephant trunk" shaped cloud extending from cloud base a tornado may already be on the ground.

1,282 tornadoes occurred in the US. in 2010, with an unknown number worldwide.

There were no tornado fatalities in Florida in 2010.

There were approximately 1,000 tornadoes reported in the United States in 2020. The actual number could be slightly different due to multiple reports of the same tornado or missed events in remote locations.

You should go in your basement or underground. If you don't have access to a basement get to a closet or bathroom in the center of you house. Stay away from windows.

There were many tornadoes in Oklahoma that day, but the infamous Oklahoma City tornado was an F5.

No, if there is a tornado or hail near a window is one of the least safe places to be.

Usually, but not always. Large tornadoes are usually more intense than strong ones. Many EF3 and stronger tornadoes are a quarter mile wide or more, but it is unusual to see EF0 and EF1 tornadoes that large.

Regardless of strength a large tornado is likely to cause more damage simply because it covers a larger area.

the results of a tornado is a damaged environment

In a tornado the winds move inwards and upwards in a circular fashion.

In a downburst the wind travels downwards and outwards in straight lines.

Also, unlike a downburst, a tornado travels across the ground, producing a path of damage.
