no there are only mexicans

San Antonio resident here!\n\nDon't sweat the tornadoes.  They're actually quite rare here; in fact, I can't remember a bad tornado that has hit the city since Hurricane Gilbert spawned one way back in 1988.  This city is usually hot and dry, and severe storms are not common.

yes.\n\nAt least the great majority of tornadoes rotate counterclockwise \n(as do all low-pressure systems) in the northern hemisphere, and clockwise in \nthe southern hemisphere, for the reason (coriolis force) given by Eric \nPeterson in response #1.  But occasionally, it would seem, northern hemisphere \ntornadoes do rotate clockwise:  S. Flora's book "Tornadoes of the United \nStates" cites an 1890 article in the American Meteorological Journal.  Its \nauthor, a J.P. Finley, states that, of 550 American tornadoes he studied, 29 \nwere deemed to have rotated clockwise.  I have not been able to find any \n"modern" study of this question.  But I believe it could be true. The region \nof swirling air that contracts to become the tornado is not itself large \nenough in extent to have its rotation dictated by the coriolis force; rather, \nit "inherits" this tendency from the great masses of air whose movement sets \nthe stage for the storms and any associated tornadoes. If the study cited is \ncorrect and representative, on occasion the direction of rotation is set by \nsome other factor, perhaps the topography in the area where the tornado forms, \nfor example.

Tornadoes form in storms all over the world, and though they have been recorded in all fifty U.S. states, they form most famously in a broad area of the American Great Plains, Midwest, as well as South known colloquially as Tornado Alley. In pure number of incidences, the United States reports more tornadoes than any other country, however, the Netherlands is the most tornado-prone country relative to land area.

Cold fronts, fast-moving jet stream, dry line, occluded front, and cold dry air moving into warm moist air will all contribute to extreme weather.  Often, in the southwest by the panhandles of Texas and Oklahoma as well as New Mexico, several of these factors will occur at the same time which can result in a severe weather outburst with several tornadoes, large hail, and lots of rain.

There are a couple reasons.  First off, Texas is the second-largest state in the US, next to Alaska.  So, there is more area in the state for tornadoes to occur.\n\nSecondly, Texas is right in the heart of Tornado Alley.  This is a place in the continental US where the airflow is just right for supercell thunderstorms (tornado-causing storms) to form, with warm, moist air rolling off of the Gulf of Mexico, dry air coming from the Mojave Desert, and cool air flowing off of the Rockies.  The combination of these air masses provide a lot of atmospheric instability, prompting thunderstorms.\n\nDue to the winds around Texas/Oklahoma, the storms are more likely to be supercells, and more likely to form tornadoes.\n\nTexas might have the most number of tornadoes in a given year, but Oklahoma actually has the most tornadoes per unit area in the US because of the wind patterns being even better for tornado formation there.

Hurricanes, tornadoes, eathquakes, cyclones....stuff like that.

Vivian villareal is known as the "texas tornado".

I have. I took pictures of this one that came right by my house. This tornado was in Tennesse so it was big for us down here. Also a few years ago a twister came through part of my town and destroyed the school i was going to. Since my town is so small and my school is so small we had class in our courthouse.

A tornado is not just wind, the fact that you can see them is either a if it drags condensation down witth them when they form (condensation funnel), or stir up dust and debris when they contact the ground. These "clouds" are actually rapidly spinning vortices (if you dont know it, look it up), that can produce winds in excess of 300 mph on the Fujita Scale (Ditto), and the stuff they can pick up and carry with them..... well, I think that about covers it.

The land in the central United States is the best breeding ground for the storms which produce tornadoes. 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 airmasses that most tornadoes form. \n\nMost tornadoes in the United States form in an area called "Tornado Alley". This area includes parts of Texas, Oklahoma, Kansas, and Nebraska. Storm chasers travel to this area because of the high concentration of tornadoes. These tornadoes are formed by thunderstorms. Some of the tornadoes in the southern states such as Florida, South Carolina, and Georgia are caused by hurricanes.

Yes,as answer 1 says,a tornado can occur anywhere.They develope in the clouds and have nothing to do with geographical pull,ect..

The U.S. is definitely the tornado capital of the world.\n\nhttp://www.usatoday.com/weather/tg/wtorwhat/wtorwhat.htm

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.

over the ocean it is hard to find out how many waterspouts (the correct term of tornadoes over water) form.  Tornadoes in the US turn out to be about 300, hurricanes/ tropical storms worldwide is about 100,  thunderstorms happen each day all over the world so it is hard to keep count.  Even us meteorologist have a hard time trying to predict hot spots for hurricane formation, it was a shock that Hurricane ivan came 8o lat, from the equator, becuase they need what is called the corriolis force to exist, near the equator the force is =0 so even we have a hard time keeping count, as well as predicting them.

There has been a slight increase in the number of tornadoes BUT the tornadoes have been on average weaker. There has not been an F5 tornoado yet this century, the longest period in recorded North American weather history.\n\nOne of the reasons for the increased number of tornadoes the past few years was the increase in the number of land-falling hurricanes. Some (but not all) hurricanes can spawn dozens of tornadoes.

Tornadoes are formed by the clashing of drasticlaly different masses of air known as fronts.  A high pressure front meets with a low pressure front and the difference in their temperatures and pressures creates a strong wind that can form into the funnel clouds known as tornadoes.  This is not to say that all colliding fronts will yield tornadoes, but there are certain elements that can increase the likeliness of a tornado forming.  The swath of the mid-west United States from N. Texas / Oklahoma through Kansas / Nebraska and into Iowa / Missouri is known as "Tornado Alley" because there are more tornados per year in this area than anywhere else in the world.
