What is the most common type of tornado?

There are no F6 tornadoes. F1 is the weakest and F5 is the most violent.\nF0-40-72 mph winds\nF1-73-112 mph winds\nF2-113-157 mph winds\nF3-158-206 mph winds\nF4-207-260 mph winds\nF5-261-318 mph winds\nNo tornadoes have been clocked at higher than 318 mph.\n\n69% of all tornadoes are F0 & 1\n29% of all tornadoes are F2 & 3\n2% of all tornadoes are F4 & 5

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.

remember......tornadoes are not sraight!!\n\nthey slant because of the moving direction of the mix of hot and cold air.

one myth could be that tornadoes occur when a small asteroid hits the atmosphere with enough rotational velocity to twist the air\n\nor that they happen when god sneezes\n\nor that there is always at least one tornado on earth at any given time

Most of the time, yes.  For instance, almost all tornadoes in the Northern Hemisphere are counterclockwise.  However, because of their small size, there is a small fudge factor that can allow the rare anticyclonic tornado, and these have been recorded.

location is the difference: hurricanes in the atlantic and east pacific, typhoons in the west pacific, and cyclones in the indian ocean and south pacific. \nhowever, tornadoes are a completely different phenomenon and are much more localized, small scale "twisters", that can at times have winds of nearly 300 MPH (way higher than the most powerful hurricanes).

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)

I don't think there's any real compelling evidence to suggest what kind of tornado season this'll be.  The only real long-term predictor is El Nino... I believe that a La Nina pattern actually trends towards slightly more tornadoes, and that we are in a slight La Nina, but the difference is not very large.  However, right now we are locked into a trough in the western US, ridge in the eastern US pattern which suggests that at least for the next week, it should be quite active.  The number of tornadoes in Oklahoma all depends on the exact location and setup of storms, things we really have no handle over beyond at most about a week, and climatologically I don't believe there are big predictors.  So your guess is as good as mine or anyone else's at this point.  Winter does not say much about spring conditions usually.  One final note: http://www.cpc.noaa.gov/products/predictions/long_range/lead01/off01_prcp.gif shows that climatologically it's more likely to be drier the next three months than usual in Oklahoma, so you might conclude that would lead to less tornadoes (though that's not always true!).

Earthquake any day!  I used to live in California - they are not so bad but Tornados scare the bejesus out me!

I've seen several funnel clouds, those are an awesome and chilling sight. By the time you notice them they're pretty well-formed. Almost all of them last a few seconds and either dissipate or roll back up into the sky. We were actually involved with a real tornado three years ago, It was an F1-F2 that stayed on the ground for almost thirty miles. I heard  the siren go off in the next town, we got the kids and the dogs in the basement. My wife and I kept going outside and looking around for something more threatening than the usual oncoming thunderstorm. After about 10 minutes we heard the freight train coming and headed downstairs. The house shook enough that the dust came down from the rafters. It lasted less than thirty seconds and then a whole lot of rain came down. The tornado missed us by 200 yards. The telephone pole in the corner of my back yard was okay, the one next to it was torn out of the ground and thrown across the road. The one next to that was torn out and thrown a hundred yards. No one in my rural neighborhood was hurt, but they did wind up bulldozing and rebuilding three homes. The home across the street had the front porch torn off and thrown over the roof, exposing a large hole in the roof deck that let in enough rain to collapse most of the ceilings. The path of damage was maybe a half-mile wide. Homes outside that range did not see much damage. I was surprised that the wind was toward the tornado, not away from it. The funnel was enough of a low-pressure point to draw the air towards it at a hundred-and-some miles an hour. The broken trees have repaired themselves, the homes and farms have been rebuilt, The only lasting reminder is a lot of sheets of tin barn roof still wrapped around treetops. We're in Northern Ohio. Moderate tornado damage is at least a yearly event in the area. Huge destructive disastrous storms like they get in the plains are a rarity.

You can thank the upper-air weather pattern for all the rain. I'm a storm chaser from Texas and these blocked patterns (upper ridge over the Rockies and upper trough over the Atlantic states) spell disaster for us looking for tornadoes across Texas, Oklahoma, and Kansas. We constantly stay dry, and you guys constantly stay wet. Until the pattern changes to a more traditional West to East flow and can kick these blocked troughs / ridges out of here, we're in for more of the same.

You can't tell by just stepping outside, unless you see a funnel cloud or something.  Tornadoes are usually created from cold fronts or occluded fronts.  You have very warm air ahead of the front, and very cool air behind it.  The difference in the air temperature pushes air up, creating an updraft.  Bottom line, tornadoes are caused by warm and cool air in the same area.  And you have to have very strong winds in the upper atmosphere.  70 to 80 mph.  That helps with the updraft.

Any of the states in the region of the country referred to as Tornado Alley.\n\nThe site of most tornadoes a year aren't actually in Kansas, but in Texas and, in some years, Oklahoma...

An F-5 tornado is capable of producing MUCH stronger winds than a CAT 5 Hurricane.  However, a tornado will damage on a much smaller scale than a hurricane.  \n\nWhile an F-5 tornado my take out multiple houses, a Cat V hurricane will take out an entire metropolis.

I love to watch them on tv. I love a thunderstorm near my house. Never been in a tornado or hurricane but they look really scary on tv. I think I would be very scared if I had to go thru a tornado of hurricane. We had a tropical storm one time with winds up to 70 mph. It was awful and lasted all night. I was so worried about the trees crashing on my house. They didn't but the ones in the far back fell. The house shook.

In the U.S., they're is a place called "Tornado Alley" because most Tornado's happen in that region.  So, where-ever else in the world they occour they must have the same conditions as Tornado Alley.\n\nJust like Hurricanes in the East are called Typhoons.\n\nTornado Alley\nhttp://en.wikipedia.org/wiki/Tornado_Alley\n\nTornado Alley Maps and Information\nhttp://www.tornadochaser.net/tornalley.html\n\nPS Tornado's over water are called Water Spouts\n\nWater Spouts\nhttp://www.australiasevereweather.com/techniques/moreadv/funnels.htm\n\nDust Devils (aka Funnels)\nhttp://www.australiasevereweather.com/techniques/moreadv/funnels.htm
