Two main weather conditions exist to create a tornado: instability in the atmosphere and wind shear in the lower atmosphere.
In the case of a tornado, instability refers to the presence of warm air closer to the Earth's surface and cooler air further above the surface. Wind shear refers to instances when the wind direction changes, and wind speed increases, with height. These conditions usually exist only ahead of a cold front and low pressure system, and are especially found in thunderstorms. The spinning motion of tornadoes is often caused by the interaction between the updrafts and downdrafts in the thunderstorm and the wind shear. The conflicting drafts cause the wind shear to tilt, and an upright tornado vortex is formed.

What are the three steps of a tornado?
The three steps of a tornado are formation, maturity, and dissipation. During the formation stage, a rotating column of air develops. In the maturity stage, the tornado reaches its maximum intensity, causing the most damage. Finally, during the dissipation stage, the tornado weakens and eventually ceases to exist.
Does rain help a tornado?
No, rain does not help a tornado form. Tornadoes are formed by severe thunderstorms with specific atmospheric conditions, such as wind shear and instability. Rain can occur before, during, or after a tornado, but it is not a contributing factor to the formation of a tornado.
Can a tornado lift up a airplane?
A tornado has the potential to lift up and throw around small aircraft, especially those that are not secured properly. However, commercial airlines are much heavier, designed to withstand turbulence, and typically remain grounded during severe weather conditions.
What are the air pressures during a tornado?
Air pressures during a tornado can vary greatly, but they typically decrease significantly in the vicinity of the tornado. The lowest pressures are usually found at the center of the tornado, where the most intense winds are located. Pressure drops during tornadoes can be drastic and are often associated with the destructive forces of the storm.
Is there lightning during a tornado?
There can be, but it is not a requirement for one. Search google for tornado lightning and look through the images to see.
What are conditions like on the ground before during and after a tornado?
before a tornado it is usally calm after a strong tornado there is lots of debris and during a tornado there are things flying everywhere
Do tornadoes only form during tornado season?
No, they can form any time of the year. The right conditions for tornadoes are just more common during tornado season.
Are tornadoes predictable?
No, not really. The national weather service can see that some conditions exist that could lead to a tornado, but they can not predict when it will happen or where.
What are the three steps of a tornado?
The three steps of a tornado are formation, maturity, and dissipation. During the formation stage, a rotating column of air develops. In the maturity stage, the tornado reaches its maximum intensity, causing the most damage. Finally, during the dissipation stage, the tornado weakens and eventually ceases to exist.
What were the conditions in Jamestown during 300 BC?
Jamestown did not exist during 300 BC.
Is a tornado living or nonliving?
A tornado is nonliving. It is a rapidly rotating column of air that forms during severe weather conditions, such as thunderstorms.
Do tornado chasers exist?
Yes
When tornado season in arkansas?
Tornado season in Arkansas typically occurs during the spring months of March, April, and May. This is when warm, moist air from the Gulf of Mexico collides with cooler, drier air from the north, creating the conditions for severe weather and tornado formation. It is important for residents to monitor weather forecasts and have a plan in place to stay safe during tornado season.
If a tornado have been seen is that a tornado watch?
No, a tornado watch is issued when the general weather conditions can produces tornadoes. If a tornado is spotted a tornado warning is issued.
What is the difference between weather warning and weather watch?
A tornado/thunderstorm watch means that weather conditions are good for tornado/thunderstorm. A tornado/thunderstorm warning, however, means that conditions are extreme and a thunderstorm or tornado is likely. Conditions for either storm are very good at this stage.
What is the most important thing for you to do if there is a tornado watch?
During a tornado watch you should stay alert. Pay attention to broadcasts and advisories for if a tornado warning is issued, especially if there is a thunderstorm in your area. A tornado watch means that conditions are favorable for tornadoes to form, but the threat is not immediate. A tornado warning means that a tornado has been spotted or detected, or there is an immediate threat of one forming.
Is a tornado watch better than a tornado warning?
Yes. A tornado watch simply means that general conditions are favorable for tornadoes to form. A tornado warning means that a tornado has been detected or may form at any moment.
