A tornado creates an area of low barometric pressure. Air spirals into the tornado and then spirals upward within it. The low pressure in a tornado cools air flowing into it, causing moisture to condense into the characteristic funnel. In many cases, though not all, the condensation reaches all the way to the ground.

How does the air pressure within a tornado compare to that of the area around it?
Air pressure in a tornado is lower than in the surroundings. Verifiable pressure drops of up to 100 millibars, about 10% of sea level pressure, have been recorded inside tornadoes.
How strong is a tornado before it hits the ground?
At ground level, there is no intensity. At higher elevetions the intensity is less than after the tornado has touched down. When a tornado touches down, it is no longer able to draw in air from below. This causes the pressure in the core of the vortex to drop, leading to an increase in wind speed.
Can a tornado cause damage without touching the ground?
Yes and no. The funnel of a tornado does not have to reach the ground for damaging winds to occur at ground level. However, if those winds reach the ground then the tornado has touched down even if the funnel hasn't.
How fast is an F6 tornado?
Theoretical winds for an F6 tornado are 319-379 mph. However, because tornado ratings are based on damage, the highest a tornado could ever be rated is F5. So the F6 rating is purely theoretical with no applications in the real world. On the enhanced scale there is no EF6 level theoretical or otherwise.
Air pressure decreases at what rate?
As you go above the sea level, pressure of air decreases.Atmospheric pressure at sea level is 1 atm.On top of mountain, air is thin which suggests less atmospheric pressure at that place.
What is the air pressure level in the center of a tornado?
Air pressure in a tornado is lower than that of its surroundings. Pressure deficits inside tornadoes have been measured as much as 194 millibars less than the surroundings.

What is the altitude at which condensation causes to form clouds?
condensation level
When was Tornado Low Level created?
Tornado Low Level was created in 1984.
Does a hurricane or a tornado have the lowest pressure?
Some of the lowest atmospheric pressures ever recorded at ground level or sea level were recorded in tornadoes and hurricanes. The lowest sea level pressure recorded at any United States-certified observing station was 892 millibars (26.34"), recorded at Matecumbe Key, Florida on September 2, 1935 in the "Labor Day Hurricane". The world record goes to Typhoon Tip when, on August of 1979, it recorded a central pressure of 870 millibars (25.69").It is not known how low pressure in a tornado can get because very few measurements have been actually taken from inside a tornado.The lowest pressure recorded in a tornado was approximately 688 millibars in Tulia, Texas on April 21, 2007.However, this was not a sea level measurement and would likely have been higher if the tornado had occurred at sea level.
What level is marked by the base of a cloud level?
The Condensation Level.
Does low pressure cause buildings to expload when a tornado passes overhead?
No, that is a complete myth. It is the wind and debris in a tornado that destroys buildings. First the pressure drop is not enough to cause significant damage to a building. The largest reliably recorded pressure drop in a tornado was 100 millibars, but a pressure difference of about 350 millibars is needed to destroy most buildings. Second, buildings are not airtight so pressure will equalize quickly. Third, even if the two statements above were not true the winds and debris in moderate to strong tornado would create enough holes to equalize pressure, if not destroy the building before the center of the tornado (where the lowest pressure is) reaches it. A tornado with a 100 millibar pressure drop would produce winds strong enough to completely level most structures.
The level does the base of clouds mark?
Condensation Level
What level is marked by the base of a cloud layer?
The Condensation Level.
The condensation occurs at the cloud base where water vapor begins condensing?
condensation level
What is lifting condensation level?
Lifting Condensation Level is altitude at which clouds begin in a rising parcel of air. Lifting condensation level(LCL) can be said to be the level to which an unsaturated air parcel can be lifted adiabatically before it becomes saturated.Remember,this unsaturated air parcel is moist
Was the Joplin tornado a level five tornado?
Yes. The Joplin, Missouri tornado of May 22, 2011 was rated EF5, the highest level on the Enhanced Fujita scale.
