Tornadoes

the Moore/bridge creek Oklahoma tornado is very very famous. the tri-state tornado is also a extremely well known tornado and then the greensburg kansas tornado is one of the most famous in the last ten years. you can also put parkersburg Iowa in that catergory as well. X

An improved and more detailed answer:

The tornado that hit New Richmond, Wisconsin on June 12th of 1899 actually started out as a waterspout that formed over Lake St. Croix. From there, it headed east in the direction of New Richmond and produced winds so strong that they carried a 3000-pound safe for an entire city block before dropping it again. The amount of flying debris was massive and, coupled with the wind, destroyed or damaged over 300 buildings.

The tornado struck on the opening day of the Gollmar Brother Circus which brought a large population swell into the small town in anticipation of the festivities that would be seen there. Just after the circus had ended for that day, at approximately 5:40 p.m., the tornado moved through the very center of town, leveling a strip of town that was 1000 feet wide and 3000 feet long. In addition, 26 different families had multiple deaths within them.

One hundred seventeen people were killed in the New Richmond tornado and 150 more people were injured. The tornado was not massive, but the path that it took and the unfortunate timing that it had made it especially destructive, as did its strong winds and F5 rating. The tornado caused $600,000 worth of damage at that time, which would be over $14 million in today's dollars !

The estimated wind speed for an F6 tornado is 318-379 mph. However this category is only theoretical. The scale as it is used only goes up to F5 as actual ratings are based on damage rather than wind speed. F5 damage is complete destruction.

Tornadoes are associated with low-pressure systems. Tornadoes typically form as a result of the interaction between warm, humid air near the surface and cold, dry air aloft, which creates a rotating column of air that can develop into a tornado under the right conditions.

The strongest tornadoes in the US typically occur in what is known as "Tornado Alley," which includes parts of Texas, Oklahoma, Kansas, and Nebraska. These areas experience a higher frequency of strong and violent tornadoes due to the clash of warm, moist air from the Gulf of Mexico with cool, dry air from the Rocky Mountains.

A hurricane can cause more damage than a tornado over because it is much bigger and so affects a larger area.

However, the damage of a tornado is more concentrated and more severe on a localized scale.

When a funnel cloud touches the ground, it becomes a tornado. Tornadoes are characterized by rotating columns of air extending from a cloud to the ground. They can be incredibly destructive and are classified based on the damage they cause using the Enhanced Fujita Scale.

Hurricanes, tornadoes, and typhoons are all types of powerful tropical storms that form over warm ocean waters. They all involve strong winds and heavy rainfall, and can cause devastating damage to the areas they impact.

Tornadoes are most likely to happen in the spring and early summer months, typically from March to June in the United States. This is when warm, moist air masses clash with cooler, drier air masses, creating the unstable atmospheric conditions favorable for tornado formation.

Florida is a state that experiences a high number of tornadoes but is not considered part of Tornado Alley. This is due to its unique geography, with the warm waters of the Gulf of Mexico providing favorable conditions for tornado formation.

The NOAA states that the current average warning time before a tornado-due to advances in weather technology, such as Doppler radar-is 13 minutes. The residents of Moore, Oklahoma, got 16 minutes lead time, but this may have been due to Oklahoma having more spotters than other areas. The technology is steadily improving, but at this point I don't think you can say 20 minutes. Going by the NOAA and Moore, Oklahoma, information, I would say that the answer is an average of thirteen minutes, with isolated incidents of a few more minutes.

The Great Natchez Tornado was a devastating tornado that struck Natchez, Mississippi, on May 6, 1840. It remains one of the deadliest tornadoes in U.S. history, killing at least 317 people and causing widespread destruction in the area. The tornado had a long track and reached estimated wind speeds of over 300 mph.

Tornadoes can stay on the ground for anywhere from a few seconds to more than an hour, depending on their size, strength, and the terrain they encounter. The average duration of a tornado on the ground is about 10 minutes.

No. Some regions have much higher tornado frequencies than other. For example, the central plains of the United States (a region called tornado alley) experiences more tornadoes than anywhere else in the world, but west of the Rockies tornadoes are relatively rare.

Tornadoes are more likely to occur in the afternoon and evening, particularly between 3pm and 9pm, when atmospheric conditions are most conducive for their formation. This is when daytime heating and convergence of weather patterns lead to greater instability in the atmosphere, increasing the likelihood of severe weather events like tornadoes.

Tornadoes can happen at any time of year and any time of day or night. However, they are most common in the spring and early summer and in the late afternoon or early evening.

Before a tornado forms, a rotating cloud can indicate the potential for severe weather. This rotating motion is often seen in supercell thunderstorms, which have the right conditions for tornado development. A rotating cloud can show that the storm is strong and organized, increasing the likelihood of a tornado forming.

Yes, Alabama is one of the states in the United States that experiences a high frequency of tornadoes. The state is situated within Tornado Alley, a region known for its frequent tornado activity. Alabama typically sees an average of around 50 tornadoes per year.

There is no rating system for tornado outbreaks, but there is for individual tornadoes. Each tornado in the Super Tuesday tornado outbreak was rated on the Enhanced Fujita scale based on the severity of the damage it caused. The scale ranges from EF0 for the weakest tornadoes to EF5 for the strongest. The Super Tuesday outbreak produced 86 tornadoes with ratings ranging from EF0 to EF4.

They don't happen instantly, but they do certainly form quickly compared with other types of storm. This simply has to do with the scale on which they exist. In weather terms tornadoes are microscale weather patterns, referring to things that are less than a few kilometers in size. (The largest known tornado was 4 km, or 2.5 miles wide. Most are much smaller.)

Because of their small size the mechanisms behind microscale systems operate quickly, causing them to form and dissipate in minutes or seconds in most cases. In addition to tornadoes, other microscale systems include turbulence and individual cumulus clouds.

The Fujita scale rates tornadoes from F0 to F5 based on how bad the damage they do is.

An F0 is the weakest category. These tornadoes break tree limbs, damage siding and gutters on homes and blow some shingles from rooftops.

A tornado does not even last a day. The longest duration ever recorded for a tornado was 3 hours and 29 minutes. Durations over an hour are rare.

The average tornado lasts about 10 minutes.

This is a fact. The low pressure associated with a tornado can cause buildings to explode as the tornado passes overhead. The rapid change in pressure inside and outside a building can create a force that can lead to structural failure and cause the building to explode.

On March 18, 1925 the Tri-State tornado tracked across parts of Missouri, Illinois, and Indiana. With a death toll of 695 it was the deadliest tornado in U.S. history. The tornado traveled 219 miles in 3 hours and 29 minutes, at times traveling at 73 mph. This makes it the farthest traveled, longest lived, and fastest moving tornado ever recorded. It was an F5 on the Fujita scale and at times was up to a mile wide.

Tornadoes can cause serious injuries such as lacerations, fractures, and head trauma to individuals caught in their path. The strong winds and flying debris are the main causes of harm to people during a tornado. It is important to seek shelter in a safe location to minimize the risk of injury.

That would be the United States. It gets more tornadoes than any other country, averaging about 1,200 per year.

The United Kingdom is the country in which you are most likely to see a tornado, as it has more tornadoes per square mile than anywhere else in the world.
