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.
What else can I help you with?
Why does the bottom of a tornado go to a tip?
The funnel of a tornado is caused by condensation, due to the pressure drop and resulting temperature drop inside it. Temperature and pressure also decrease with increasing altitude, making it easier for condensation to occur and causing the funnel to be wider at the top. At the bottom, the pressure and temperature may only be low enough for condensation at the very center of the tornado.
How does the air pressure within a tornado compare to that of the area around it?
The air pressure within a tornado is typically lower than that of the surrounding area. As the strong winds of a tornado rotate, they create a low-pressure center at the core of the vortex, which can cause a significant drop in air pressure.
What is the air pressure in the center of a tornado?
The pressure inside a tornado is very low. Exactly how low is unknown as only a few measurements have been taken. Generally it is belived that the lower the pressure, the stronger the tornado The lowest pressure recorded to date was in an EF2 tornado at 688 millibars, which was 194 millibars less than the surrounding area.
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.
Unit of 1 atmosphere used to describe the pressure of gas?
Standard atmospheric pressure at sea level is equal to : 101325 Pa ....[ 1.0 Pa = 1.0 N / m^2 ] 101.325 kPa 1013.25 millibar 14.696 psia 2116 psfa 760 mm Hg 29.92 in Hg These equivalents to one atmosphere pressure are very convenient for making pressure unit conversions.

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.

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.

When was Tornado Low Level created?
Tornado Low Level was created in 1984.
What is the altitude at which condensation causes to form clouds?
condensation level
What level is marked by the base of a cloud level?
The Condensation Level.
The level does the base of clouds mark?
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.
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.
When does snivy learn leaf tornado?
Snivy learns leaf tornado at level 16 and at level 17 it will evolve into servine.
