There aren't actually more tornadoes now, we're just better at detecting them. Back in 1965 we only had primitive weather radar and did not know where in a storm tornadoes would often form. As a result, we ended up missing most tornadoes of F1 and F0 strength, which we now know account for about 90% of tornadoes in the U.S.
There were more significant (F2 or stronger) tornadoes in 1965 than there have been in any year in the past 39 years, suggesting that 1965 saw more tornado activity than actually occurs today.
Yes. Some tornadoes may last for more than an hour, but such cases are rare. Most tornadoes do not last more than 10 minutes.
Tornadoes are more frequent at night because the atmosphere is more stable, allowing for the development of strong thunderstorm complexes, which can produce tornadoes. Also, nighttime tornadoes may go unnoticed or be more dangerous because people are sleeping and may not receive timely warnings.
Tornadoes are more common during the day, but they happen at night fairly often as well. About 58% of tornadoes occur during the day.
They don't. The US has 40 times the number of tornadoes that England has, and they tend to be much more intense- less than 10% of English tornadoes are strong, 42% of US tornadoes are strong storms.
Doppler radar, which even now is the most valuable tool in detecting and predicting tornadoes.
There were 897 recorded tornadoes in the U.S. in 1965. Note however that at this point in history the majority of weak tornadoes were missed, and most tornadoes are weak. The actual number of tornadoes was probably much higher than this figure, possibly more than double.
Tornadoes killed 53 people in Michigan on April 11, 1965
There is some evidence that tornado frequency might be increasing but it is difficult to determine as with more advanced technology and greater knowledge of tornadoes we are now finding tornadoes that we would have previously missed.
Currently, on November 24, 2010 there are no tornadoes occurring.
Florida frequently has tornadoes, though several states have more tornadoes annually.
Indiana experiences more tornadoes.
Tornadoes are generally more dangerous as they are stronger than waterspouts.
No. Texas gets more tornadoes than any other state.
The Palm Sunday tornado Outbreak produced violent (F4-F5) tornadoes in the states of Iowa, Illinois Indiana, Michigan, and Ohio. Four violent tornadoes occurred in the area around Goshen, Indiana while a pair of F4 tornadoes tore through a portion of southeastern Michigan. A string of tornadoes, one of which may have been an F5, tore a series of successive paths from near Lafayette, Indiana to near Cleveland, Ohio.
On average tornadoes kill more people than lightning
The continental United States can and does have tornadoes. It has more tornadoes than anywhere else.
Generally not. Tsunamis cause destruction along much larger areas than tornadoes do. However tornadoes are significantly more common
