what happens inside a tornado?

A tornado is basically like a giant vacuum cleaner.  They are frightening and amazing all at the same time!\n\nEverything you ever wanted to know about them can be found in this excellent resource from NOAA.

Get a weather radio if your town doesn't already have weather warning sirens.  If a Tornado Warning is given, get in the basement of your home or your most internal room without windows.\n\nIf you're in a trailer or car, GET OUT and get yourself in a ditch and hold on.  That train sound isn't a train.

i read in a tornado book that i bought, tornado alley in the U.S. gets the most tornadoes in the whole world.  Conditions are just right for it here.  There is nowhere else that tornadoes are common, but tornadoes can happen anywhere

there are 2 kinds Microburst and Macrobusts. They are both the same only the micro is weaker, the conditions for a microburst are the same for a tornado. Only air pressure comes down and hits the ground                                                                   and air is sort of sucked into the sky.......This happened in my hometown about a year ago, the roof on my school was lifted up about 1 foot and slammed back onto the school (just to give you a idea of the power of a MACroburst)

This is actually more of a coincidental event to a tornado.  When large hail is present within a thunderstorm, the refraction of light from the hailstones will occasionally cause the cloud to take on a  green hue.  This does not directly indicate the possiblity of a tornado, simply that there is large hail within the thunderstorm.  Incidently, just about all thunderstorms with tornadoes have large hail.  But one can't say because a thunderstorm has large hail, there is a tornado.

No, don't think a tornado is a possibility. But if they tied themselves together and lit their farts, do you think they would take off?  :)

Short answer, they are called "tornado;" as you will see below, tornadoes usually rotate in a counter-clockwise direction in the northern hemisphere, clockwise in the southern.  In the rare event of it spinning in the opposite direction, which I believe was the nature of your question, it is called an "anticyclonic tornado."\n\nTornadoes normally rotate in a cyclonic (counterclockwise) direction in the northern hemisphere, as the warm air in which thunderstorms usually form sweeps north and jet streams come from the west, creating a situation in which the storms rotate. In the northern hemisphere, this rotation is counterclockwise, and in the southern hemisphere, clockwise. The tornadoes usually rotate the same way. Sometimes opposite direction swirls develop under a thunderstorm. About 1 in 100 tornadoes in the northern hemisphere rotate in an anticyclonic direction.\n\nI hope this helps.

Get an empty 2 liter soda bottle and fill it half-way with water. Hold the top and spin it in a circular motion. This will cause the water to look like a tornado.  Technicaly, a tornado is caused by a cold air mass "wedging" a warm air mass up. Another mass of air then clashes into them and causes the air to spin.

!!!!!!TORNADOES!!!!!!\n\nur siting right next 2 me hahahahaha!!!!

In the US Midwest, tornadoes are usually formed when a cold, dry air mass moving south from Canada collides with a warm, moist air mass moving north from the Gulf of Mexico (or Baja California, or the Atlantic, or what have you). \nThis produces large thunderstorm clouds known as supercells, which can produce heavy rains, hail, and tornados. \nTornados are formed in areas of the supercell called mesocyclones; which draws air into the storm. When you hear meteorologists talk about the "hook echo" on the radar, they're pointing out the mesocyclone. The best simple explanation (so far) for why the tornado starts to rotate is the phenomenon of vertical wind sheer, where wind changes direction at different elevations.\nSo, if you have access to a weather radar; you can see hook echos like the one below. If you have a wind velocity view (some do, some don't), look for a large difference in wind speed and direction around that hook echo.

I don't think tornados have a preference. It seems they like either one, especially if there's a trailer park! Seriously though, they can happen anywhere when cold air meets warm air. That's all I know about how they're formed. \nBut, from watching the weather reports about tornadoes in "Tornado Alley", I've noticed it doesn't matter if areas are incorporated or unincorporated. However, if it is unincorporated, there's definitely a lot less damage to structures (buildings). But even in an unincorporated area, buildings can be smashed.

Actually, scientists understand a lot about tornadoes, but cannot completely predict them because they happen on such a micro-scale compared to other weather phenomenae.  Scientists can predict when conditions are favorable for tornadic activity (like when a tornado warning is issued), but can't predict excatly where one will occur until moments before hand.

They are very rare, but I think as long as there is cold air clashing with warmer air (which can happen even in the winter), you can create conditions favorable to tornado developement. We had a severe snow storm in which we had thunder and lightning, the sky even turned slightly yellow....scary.

According to answers.com\nhttp://www.answers.com/tornados%20\n\n"Tornadoes develop from severe thunderstorms, usually spawned from squall lines and supercell thunderstorms, though they sometimes happen as a result of a hurricane. They are believed to be produced when cool air overrides a layer of warm air, forcing the warm air to rise rapidly, though tornadoes over water (waterspouts) frequently are observed forming in the absence of convection or apparent strong surface temperature differences. Tornadoes, lightning, and sometimes hail are associated with thunderstorms. Many tornadoes appear at the tail end of mesocyclones. On weather radar screens, a characteristic "hook echo" marks the area where tornadoes are likely to exist."\n\nThe reference will give good idea for how do tornados form

You like tornadoes.\n\nCoach

Well winds in a tornado can reach speeds of 300 mph, this in itself is enough to cause total destruction.\n\nPressure is also lowest at the center of a hurricane, or any other low-pressure system. The air is being pulled up away from the ground and thus the pressure is low.

Go to metacafe, and put in the search space, a tornado is born.  It's an awesome video.
