Tornadoes can merge together, yes, and vortex physics predict that the combined tornado will be larger than either of the merging tornadoes. However, most tornado mergers involve a large tornado absorbing a small one, so the larger tornado is not affected very much.
Though tornadoes are fairly common in many states outside tornado alley, the one with the most is Florida.
Not really, tornado alley is one of the areas most frequented by the strongest tornadoes, rated EF4 and EF5. However, even in tornado alley you are unlikely to be hit by such a strong tornado.
Not really, there is a such thing as a multiple vortex tornado. These tornadoes have smaller, stronger vorticies moving around inside of the tornado. Sometimes a multivortex tornado can have the appearance of being two or more tornadoes but it still is one tornado.
When two tornadoes meet, regardless of intensity, they will merge to form one tornado.
Yes, there was at leas one confirmed tornado in Houston in 2000,
When two tornadoes combine they simply merge to form a larger tornado. Usually it happens when one large tornado absorbs a smaller one.
Yes. Some twisters have touched down and joined together to create a big tornado.edit: when tornadoes form like that its called a multivotex tornado
When tornadoes merge they simply become one tornado large than either of the original two. It is an unusual occurrence and most of the time that it does happen it involves a large tornado absorbing a small one without being much affected.
No large tornadoes have struck Baltimore since official records began in 1950. Several weak tornadoes and one significant (F2) tornado have hit the city. No tornadoes have struck Baltimore in 2015 as of June 11.
It appears to have been one tornado.
Tornadoes can merge, but it is rare. Most often it occurs when one large tornado absorbs a smaller one.
If two tornadoes meet, they will merge to form one tornado.
If 2 tornadoes collide they will merge into one tornado.
It is rare for tornado to actually merge, and when it does happen it usually involves a large tornado absorbing a smaller one. In the rare cases that tornadoes do merge they simply form one bigger tornado.
A tornado anywhere is a violent event. If you mean by the technical definition of a violent tornado, one rated EF4 or EF5, such tornadoes do occur fairly regularly in Tornado Alley, but make up a very small minority of the tornadoes that occur there. As with most places, most of the tornadoes in Tornado Alley are rated EF0 or EF1.
Oklahoma City has been hit by many tornadoes. The most famous Oklahoma City tornado was the one which struck on May 3, 1999. That tornado was a mile wide and was rated F5.
They form in Tornado Alley for a couple of reasons. One of them is because of the weather. It is humid there. But, tornadoes can also form outside of Tornado Alley. They can form anymore!
