Tornadoes
A tornado or twister is a violent, rotating column of air which typically has a speed ranging from 177 km/h to over 480 km/h. This devastating windstorm is usually characterized by its funnel-shaped cloud that extends toward the ground.

Tornadoes can form in a variety of topographical settings, but they are more common in areas with flatter terrain. Flat land allows for easier air flow and less friction, which can contribute to the development and strength of tornadoes. However, tornadoes can still occur in mountainous or hilly regions under certain conditions.
What happens in the atmosphere when there is a tornado?
Tornadoes form during thunderstorms. These storms usually developing a warm, moist air mass ahead of a cold front (where cold air moves in) or dry line (where dry air moves in). Within the storm air rises rapidly in a strong updraft. The rising air cools causing the moisture to condense and release energy. At the same time, regional winds change significantly in speed and direction with height. This causes the updraft of the storm to rotate. It is form this rotation that the smaller, more intense circulation of a tornado may form.
Within the tornado itself air spirals inward and upward rapidly around a center of intense low pressure. Because of the pressure drop air cools within the tornado, causing moisture to condense to form the visible funnel.
What does a tornado do to your atmosphere?
A tornado can significantly disturb the atmosphere by creating abrupt changes in pressure, temperature, and wind patterns. It can also lead to the mixing and transport of air masses, affecting local weather conditions. Additionally, tornadoes can introduce dust, debris, and pollutants into the atmosphere, impacting air quality.
Is there a place in Nebraska where there are no tornadoes?
No place in Nebraska is completely immune to tornadoes as they can occur anywhere in the state. However, some areas have lower tornado occurrence rates compared to others. It is important to always be prepared and have a tornado safety plan in place regardless of where you are in Nebraska.
Name two ways both hurricanes and tornadoes cause damage?
Tornadoes destroy property in two ways. Powerful winds can tear apart or collapse structures. Second, the winds can carry objects at high speeds, this flying debris can make damage more severe than the wind alone.
What happens to a beam bridge during a tornado?
A beam bridge can be damaged or destroyed during a tornado due to high winds causing stress on the structure. This can result in the beams bending, twisting, or collapsing under the intense forces of the tornado.
Was there a tornado in Murphy NC?
Yes, there was a tornado in Murphy, North Carolina on April 27, 2011. The tornado was rated an EF2 on the Enhanced Fujita scale, with estimated peak winds of 125 mph. It caused significant damage to homes and businesses in the area.
Did the tornado hit mayfield Kentucky?
Yes, an EF1 tornado touched down on N-15th street near the football stadium on October 14, 2012. Not a lot of damage and no one was seriously hurt.
What geographical features and weather patterns are present when a tornado takes place?
Tornadoes typically occur in regions with flat terrain, such as the Great Plains in the United States. They often form in conjunction with severe thunderstorms, which have strong updrafts and wind shear. Tornadoes can be accompanied by heavy rain, hail, and lightning.
Where do you go when in your basement during a tornado?
During a tornado, you should go to the lowest level of your house, like a basement if you have one. Stay away from windows and doors, and seek shelter under a sturdy piece of furniture if possible. Be sure to have a supply of essentials such as water, blankets, and a flashlight in your designated safe area.
What part of the basement is the safest area to hide from tornadoes north east south or west?
The safest area in a basement to hide from tornadoes is typically the area that is furthest away from windows and exterior walls. In most cases, this would be the northeast corner. It is important to choose a location where you can easily seek shelter and protect yourself from debris and potential structural damage.
Is gwinnett getting hit with a tornado?
Thus far on March 2, 2012 there have been no tornadoes reported in Gwinett County, Georgia, however a tornado warned thunderstorm did pass through, and it is possible that a tornado touched down in or moved through the county.
Is there going to be a tornado in louisville Kentucky?
There is no way to predict the exact occurrence of a tornado in Louisville, Kentucky. It's always important to stay informed about weather updates and be prepared in case of severe weather warnings. Stay tuned to local authorities and weather alerts for the most up-to-date information.
Was There ever a EF6 Tornado Rank?
Sort of. On the original Fujita scale theoretical categories F6 to F12 were plotted, but they are never used, as ratings are based on damaged, and an F5 tornado leaves nothing left to destroy. Since it was never used, the Enhanced Fujita (EF) scale did away with it completely, giving any tornado with estimated winds over 200 mph a rating of EF5.
Does a late afternoon calmness and a yellow sky are good warning signs that a tornado could occur?
No. However, a calm period during a thunderstorm with dark clouds still overhead is a possible warning sign. A green or yellow sky under these conditions is often informally associated with tornadoes, though in and of itself it merely indicates that a storm is very strong. Also be on the lookout for any sign of rotation in the clouds.
Do tornadoes always follow the rotation of the earth?
No. While most tornadoes rotate in a direction that matches earth's (clockwise in the northern hemisphere and counterclockwise in the southern), a small percentage go against this. The origin of the spin in tornadoes is not directly related to earth's rotation. Most tornadoes also move in an easterly direction, but not always.
What state has the most tornado deaths?
It is difficult to determine, as there is no exact way of saying which tornadoes are the worst. Overall, Texas has the most tornadoes and the most tornado deaths. Kansas has the highest concentration of tornadoes. Oklahoma appears to lead in the number of violent (F4 and F5) tornadoes and is tied with Alabama in the number of F5 tornadoes. Mississipi has the highest number of tornado deaths per capita.
How is a storm and a tornado similar?
A tornado is a type of storm. A storm is characterized by strong winds, heavy or dangerous precipitation, thunder and lightning, or some combination of those. A tornado produces the fastest winds of any storm on earth.
How do tornadoes suck stuff up?
The convection of relatively warm air creates a circular, upward movement, causing a low pressure zone (partial vacuum). Air moves from areas of high pressure to areas of low pressure, like the center of the hurricane.
What kind of weathering is a sign of tornadoes?
Signs of a potential tornado include rotation in the clouds, a persistent lowering of the cloud base, and a hole opening up in the clouds near the back of a storm (these are all potential precursors). Other signs include a funnel or con shaped extension of the cloud base, and swirling debris on the ground, indicating that a tornado or funnel cloud has formed.
Where can you get research on tornadoes?
Much information on tornadoes is provided by branches of NOAA, the National Oceanic and Atmospheric Administration, most notable from the National Weather Service and the Storm Prediction Center. See the link below for NOAA's website.
When where are the most current tornadoes in the us?
It depends on how you define most severe.
The deadliest tornado on record was the Daulatpur-Saturia tornado of April 26, 1989. It struck portions of Bangladesh, killing over 1,300 people.
The costliest tornado in terms of property damage was the Joplin, Missouri tornado of May 22, 2011 with damage costing $2.8 billion.
The strongest tornado on record is impossible to determine with any certainty, as most F5 and EF5 tornadoes produce similar damage, making it hard to determine if one was stronger than another. Here are to potential candidates: Other tornadoes may also qualify, but in many cases the ncessary information is not available, especially for older tornadoes.
- The highest wind speed on record was measured on the Oklahoma City ornado of May 3, 1999 at 302 mph. But other tornadoes may have been stronger as wind speed measurements from tornadoes are rare.
- The most intense damage to be photographed was after the Jarrell, Texas tornado of May 27, 1997 where an entire subdivision was erased, leaving behind nothing but mud and concrete slabs. Some attribute the severity of this damage to the tornado's slow movement allowing it to tear away at the same spot for a long time.
What is the safest corner to go to in a basement during a tornado?
The safest corner to go to in a basement during a tornado is the corner farthest away from the direction the tornado is approaching from. This helps reduce the risk of debris hitting you. If possible, seek shelter under a sturdy object like a table to add an extra layer of protection.
Is it safe to be in your car in the garage during a tornado?
No. It doesn't take a very strong tornado to pick up or flip a car. If you are in a car and a tornado is coming you should go to the nearest sturdy building or underground shelter. If no shelter is nearby get out of the car and lie in a ditch or depression.
