How many tornados per year are recorded in the U.S.? Which region records the most in the world?

Although tornadoes can happen at any time of year, they are especially common during the spring and early summer. May and June are the peak months in terms of numbers of tornadoes, but April appears to be the deadliest month—an average of 27 tornado deaths occurred during this month between 1950 and 1999; and one of the all-time worst tornado disasters occurred on April 3-4, 1974, when 148 twisters struck 13 states causing more than 300 deaths.

The best place would be to contact the National Weather Service for the area you are studying.  They should have data on all weather patterns collected from weather stations all around the country.  Some weather stations have only local data.  \nYou could also check the weather almanac for the specific year you would like to research.  You can usually find precip totals for every year that records have been kept.

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 is no official tornado season because they can occur at any time. Unofficially, though, the months of spring and early summer usually have the highest rate of tornado activity, particularly in the Midwest.

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

Most tornadoes in the United States form in an area called "Tornado Alley". This area includes parts of Texas, Oklahoma, Kansas, and Nebraska.

The most number of thunderstorms occur in the tropics, or the zone either side of the equator from about 23.5 degrees north latitude to 23.5 degrees south latitude. \nAs far as the most powerful storms are concerned, the ones with the greatest rainfall tend to be in the tropics, because of so much moisture available. However, thunderstorms that cause severe weather, including damaging winds, hail, and even tornadoes, are generally in the middle latitudes. The middle portions of North America, i.e., the Plains states of the U.S., have the greatest number of tornadoes than any other place in the world.

In the United States (and predominately worldwide), the intensity of a tornado is measured on the Fujita-Pearson Tornado Scale (also known simply as Fujita scale).

If you get cable or satellite TV, you can see all you want, mostly on The Weather Channel.\n\nCheck TORNADOES entry in blog at http://360.yahoo.com/ki_te_moana for urls to places with lots of tornado info.  Such videos are highly sought after and dangerous to acquire, not likely to be free.  But there are many now in existence.\n\nThey have GOT to be FOR SALE somewhere, but you cannot see how good one is until you view it.\n\nDid you Google 'Tornado Videos for Sale' ???\n\nAlso try 'Kansas Tornado Videos'\n         'Oklahoma Tornado Videos'\n          'Texas Tornado Videos'\n\nThe meteorology professors must use them in class, too.\n\nTherefore, try 'Instructional Tornado Videos'

Go to Yahoo or Google and search for Tornado Alley, that is the midwest part of the u.s. where tornados are most prevalent.. hope it helps!!

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

Tornado Alley might have the MOST frequency of tornadoes, but the worst type of tornadoes , I believe,are "waterspouts": tornadoes that form on oceans (yikes! where to hide from that one?)  They occur fairly around warm waters (including Florida).\n\nCheck these chilling pictures out\n\nhttp://en.wikipedia.org/wiki/Image:Trombe.jpg\nhttp://www.photolib.noaa.gov/historic/nws/images/big/wea00312.jpg

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.

Tornado Alley refers to the area of the United States affected most frequently by the strongest tornados.  The "heart" of tornado alley includes Nebraska, Kansas, Oklahoma and Texas - but tornado alley extends from North Dakota south to Texas and east into Ohio (including parts of at least 18 states).\n\nSee the web site "www.tornadochaser.net" for more detailed information.  From that site: "If you were to be exact about tornado alley, it would really be made up of hundreds of little strips, and never one large alley.  Tornado alley maps are all made up of a general area from data taken over a long period of time. Tornado alley should be thought of on a more yearly basis also, since weather patterns can change, making some states harder hit one year versus others, like Illinois in 1925, 1974 and 2004."

The worst blizzards occur in the world's greatest mountain ranges and usually at high altitude.  I don't think there'll be any accurate record of the worst one ever but there's several that have lasted for many days or even weeks with wind speeds often in excess of double that of a hurricane.

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.
