how does it from

The most destructive and deadly tornadoes occur from supercells, which are rotating thunderstorms with a circulation called a mesocyclone.Tornado formation is to be dictated mainly by things which happen on the storm scale, in and around the mesocyclone. results from the VORTEX2 program suggest that once a mesocyclone is underway, tornado from is related to the temperature differences across the edge of downdraft air wrapping around the mesocyclone. Modeling studies of tornado formation also indicate that it can happen without such temperature patterns; and in fact, very little temperature variation was observed near some of the most destructive tornadoes in history on .

how is it rate

How is tornado strength rated?The most common and practical way to determine the strength of a tornado is to look at the damage it caused. From the damage, they can estimate the wind speeds. The EF-Scale takes into account more variables than the original Fujita Scale (F-S assigning a wind speed rating to a tornado, incorporating 28 damage indicators such as building type, structures and trees. For each damage indicator, there are 8 degrees of damage ranging from the beginning of visible damage to complete destruction of the damage indicator. The original F-scale did not take these details into account. The original F-Scale historical data base will not change. An F5 tornado rated is still an F5, but the wind speed associated with the tornado may have been somewhat less than previously estimated. A correlation between the original F-Scale and the EF-Scale has been developed. This makes it possible to express ratings in terms of one scale to the other, preserving the historical database

where does a tornado occur

tornado occur over low land. like great plain.The land in the Great Plains is relatively flat, which allows cold dry polar air from Canada to meet warm moist tropical air from the Gulf of Mexico. It's along the front between the two air masses that most tornadoes form


Most tornadoes in the United States form in an area called "Tornado Alley". This area includes parts of Texas, Oklahoma, Kansas, and Nebraska.storm chaser travel to this area because of the high concentration of tornadoes. These tornadoes are formed by thunderstorm. Some of the tornadoes in the southern states such as Florida, South Carolina, and Georgia are caused by hurricane.

what to do

before it is important to know that you cannot depend on seeing a funnel: clouds rain may block your view. The following weather signs may mean that a tornado is approaching:

  • A dark or green-colored sky
  • A large, dark, low-lying cloud
  • Large hail
  • A loud roar that sounds like a freight train

If you notice any of these weather conditions, take cover immediately, and keep tuned to local radio and TV stations or to a NOAA weather radio.

during At Home

Pick a place in the home where family members can gather if a tornado is headed your way. One basic rule is AVOID WINDOWS. An exploding window can injure or kill.

The safest place in the home is the interior part of a basement. If there is no basement, go to an inside room, without windows, on the lowest floor. This could be a center hallway, bathroom, or closet.

For added protection, get under something sturdy such as a heavy table or workbench. If possible, cover your body with a blanket, sleeping bag, or mattress, and protect your head with anything available--even your hands. Avoid taking shelter where there are heavy objects, such as pianos or refrigerators, on the area of floor that is directly above you. They could fall though the floor if the tornado strikes your house.
