Tornadoes

There is no given size. Most are fairly small (in weather terms) ranging between 50 and 200 yards wide. However occasionally these tornadoes can grow to over a mile wide with some exceeding 2 miles.

The lifespan of a tornado varies greatly and can last from a few seconds to over an hour. The majority of tornadoes last less than 10 minutes, but some long-track tornadoes can persist for an hour or more. The size, strength, and environment of the tornado all play a role in determining its lifespan.

Tornadoes are not rated by size, they are rated by how severe the damage is from EF0 to EF5. For example if a tornado hits a town, destroying trailers and tearing off roofs but no worse, it is rated EF2, regardless of its size.

Although tornadoes with higher ratings tend to be larger, this is not always the case.

It is impossible to say for certain, bu tornadoes have probably been occurring on earth since the Precambrian time hundreds of millions, if not billions of years ago.

The speed at which a tornado travels over land can vary significantly depending on factors like wind speed, terrain, and other atmospheric conditions. On average, tornadoes move at speeds of 30-70 miles per hour, but some have been recorded moving as fast as 70-80 mph or even faster.

There is no given size for an F5 tornado as tornado ratings are based on damage severity, not size.

A tornado is rated F5 if well-built houses are blown clean off their foundations.

F5 tornadoes have come in various sizes, ranging from as small as 100 yards to over 2 miles wide.

That being said, F5 tornadoes are usually very large, averaging about half a mile wide.

Hook echoes in a radar image are a sign of possible tornadoes.

That is no true. Tornadoes occur almost all over the world and have touched down on every continent except Antarctica.

The U.S. however, gets more tornadoes and stronger tornadoes than any other country. This is due to the fact that the country has a very large land area and has a large region where 80% of its tornadoes occur called Tornado Alley.

Tornado Alley experiences the perfect combination of colliding air masses, wind shear, and a strong "cap" of stable air for the formation of tornadic supercells. Other tornado producing regions in the world, such as in Argentina, do not have quite the same setup.

That can have different answers. There are 6 levels on the Fujita Scale ranging from F0 to F5 (EF0 to EF5 on the Enhanced Fujita scale). But these are only levels of intensity and do not divide tornadoes into distinct types.

Type 1: also known as supercell tornadoes. These tornadoes, which form from the mesocyclone of a supercell, are the most common type and are generally the strongest. They are the only ones that can reach EF4 an EF5 intensity. On occasion these tornadoes can become very large.

Type 2: also known as landspouts or waterspouts* depending on where they occur. These tornadoes most often form from developing thunderstorms. They are weaker on average than supercell tornadoes but on rare occasions can be as as strong as EF3. When they occur as landspouts they often produce a characteristic dust tube.

Other tornado-like circulations such as dust devils, fire whirls and gustnadoes are not considered tornadoes.

*Type 1 tornadoes can occur as waterspouts as well, though not as often as type 2. They are called tornadic waterspouts. Waterspouts are usually not officially counted as tornadoes unless they hit land.

The funnel of a tornado is the result of moisture inside a tornado condensing. As the air rises it cools, allowing more moisture to condense, therefore the funnel gets wider the higher up you go.

A wall cloud is a large, lowering cloud formation that extends beneath the base of a thunderstorm. It often has a wall-like appearance and can be rotating. Wall clouds are typically dark and turbulent, and can sometimes be a precursor to tornado formation.

No, tornadoes typically form in warm and moist environments in the presence of a strong vertical wind shear and unstable atmosphere. Cold and windy conditions with no clouds are not conducive to tornado formation.

It is not known for certain, but it is believed that tornadoes dissipate when cold outflow from a storm undercuts the updraft that powers a tornado and cuts off the supply of warm air that fuels it.

Illinois gets tornadoes because it is located in Tornado Alley, a region in the central United States known for frequent tornado activity. Factors such as warm, moist air from the Gulf of Mexico meeting cooler air from the north create the instability necessary for tornado formation. Additionally, Illinois experiences strong weather systems that can produce thunderstorms and tornadoes.

The Great Plains experience a wide range of weather conditions, including hot summers, cold winters, and severe weather events such as tornadoes and blizzards. The region also experiences strong winds due to its relatively flat terrain, which can contribute to rapid weather changes. Overall, the Great Plains' weather is characterized by variability and can be both challenging and unpredictable.

Yes, both hurricanes and tornadoes spin around a center of low pressure, known as the eye in a hurricane and the mesocyclone in a tornado. This rotation is due to the Coriolis effect and atmospheric dynamics.

Whirlwinds can help with seeding clouds and dispersing seeds, playing a key role in the ecosystem's natural processes. They also contribute to air circulation and can help reduce heat by bringing cooler air to the ground. However, they can also cause damage and destruction when they become tornadoes or dust devils.

Tornadoes can form near oceans, especially in coastal areas where warm, moist air from the water can interact with cooler air over the land. These interactions can create the conditions suitable for tornado development. However, the majority of tornadoes in the United States occur in the central part of the country in an area known as Tornado Alley.

Chicago is a relatively small target for a tornado to strike and so unlikely to be hit.

So it really is only by chance that tornadoes have missed Chicago.

However, tornadoes have occurred in the Chicago area, so it is entirely possible for one to hit the city itself.

80 percent of tornadoes occur between March and June, with the peak tornado season typically falling in May in the United States. Tornadoes can happen at any time of the year, but spring and early summer are the most active periods due to the clash of warm and cool air masses.

Tornadoes do not occur in polar regions, because the cold air does not provide enough energy. They do not occur in extreme desert regions because there is not enough moisture to fuel the right kind of thunderstorm.

They don't. Farmers get hit by tornadoes just like other people do. It's just not heard of as much because a tornado hitting a farm is less likely to make big news than one hitting a town. There is no way that people can prevent tornadoes.

Yes, tornadoes in the Northern Hemisphere typically rotate counterclockwise, while tornadoes in the Southern Hemisphere rotate clockwise. This rotation is due to the Coriolis effect caused by the Earth's rotation.

Not necessarily. While turbulent clouds indicate unstable atmospheric conditions that could lead to severe weather like tornadoes, the presence of bumps alone is not a guarantee that a tornado will form. Tornadoes typically form due to a complex combination of factors such as wind shear, instability, and moisture.
