Before a tornado occurs, the atmosphere needs to be unstable, with warm, moist air at the surface and cold, dry air aloft. Wind shear is also crucial, as it creates the rotation necessary for a tornado to form. Storm systems or supercell thunderstorms often provide the ideal conditions for tornado development.

What part of the storm does a tornado form in?
A tornado usually forms from a mesocyclone, which occurs in the updraft or rear portion of some thunderstorms.
Do tornadoes go off the radar?
Sometimes tornadoes can evade radar detection. This most often happens if the tornado is short lived, and thus is missed as the radar beam rotates, or occurs far away from the radar. Fortunately this occurs less often with strong tornadoes.
What weather occurs before a tornado?
Tornadoes most often form in the rear portion of a thunderstorm, and are generally preceded by heavy rain, thunder and lightning, and occasionally large hail.
What would the name of a developing tornado be before it reaches to the ground?
Before it reaches the ground a developing tornado is known as a funnel cloud.
When will the next tornado hit Scotland and where?
It is impossible to make long term predictions for when and where a tornado will occur. At best, we will know about this next tornado a few minutes before it forms.
Where does the weather happen before a tornado?
The weather that precedes a tornado, including heavy rain and hail generally occurs in the front part of a supercell thunderstorm, with the tornado closer to the back.
How much warning can a person expect before a tornado occurs?
The average lead time for a tornado warning is 15 minutes. Sometimes you get more warning, sometimes less.
What happens before a tornado strikes?
It varies but most often it stops raining a few minutes beforehand. A break in the clouds may be seen, a sign of a downdraft that helps the tornado form. A number of tornado survivors recall it being unusually quite just before the tornado hits.
Where is the potential energy present before the tornado occurs?
The potential energy before a tornado occurs is stored in the form of warm, moist air at the Earth's surface. This air has the potential to rise and release its energy as the storm system intensifies, leading to the formation of a tornado.
What happens to living and non living things if a tornado happens?
The area in which the tornado happens can erode the area away cause the animals that lived there to have no home or die of the tornado
What happens before the tornado hits the ground?
Before a tornado hits the ground, a rotating column of air forms in the storm cloud known as a funnel cloud. This funnel cloud extends towards the ground, and once it makes contact, the tornado is then officially considered to have touched down.
What is the name of a tornado that occurs on land?
A tornado. Tornadoes usually occur on land anyway.
What do you call a tornado that occurs on land?
It is simply a tornado. Most tornadoes occur on land.
What is a tornado touchdown?
When a tornado touches down it means it has reached the ground and can now cause damage. It is not a tornado until this occurs,
Why does everything get calm before a tornado?
The calm before a tornado is due to the changing wind patterns and pressure within a tornado-producing storm. As the storm intensifies, air begins to rise rapidly, creating a calm and still area near the center of the storm before the tornado forms. This calm period is often short-lived and is followed by the destructive tornado itself.
Why do tornadoes look like spaghetti?
It is rather unusual for a tornado to look like spaghetti. If a tornado does take on such an appearance it most likely means the tornado is dissipating or "roping out." It is believed that this occurs when cold air chokes of the warm air that feeds the mesocyclone, the rotating updraft that drives the tornado. When this happens the tornado begins to shrink and weaken. Winds within the parent storm can somtimes cause a tornado at this stage to bend into unusual shapes.
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
