It is not known for certain, but it is believed that tornadoes dissipate when cold outflow from a storm undercuts the updraft that powers a tornado and cuts off the supply of warm air that fuels it.
No. Tornadoes do not damage the atmosphere.
Nearly all tornadoes in the southern hemisphere do. However in the northern hemisphere most tornadoes rotate counterclockwise. A small percentage of tornadoes rotate opposite of what is normal for their hemisphere. These are called anticyclonic tornadoes.
Tornadoes in the southern hemisphere spin clockwise with the exception of rare anticyclonic tornadoes.
You can't get rid of tornadoes. They dissipate naturally.
Tornadoes do not create anything; they only destroy.
Yes. All tornadoes dissipate. Most last no more than a few minutes.
There is no real research being done to that end. It is generally acknowledged by scientists that tornadoes cannot be stopped.
Since official record began in 1950 up through the end of 2012, there have been 3,139 recorded tornadoes in Florida. Tha actual number of tornadoes is probably much higher, as prior to the 1990s, many of the weaker tornadoes were missed.
Preliminary estimates show that there have been 1286 tornadoes so far in the U.S., though the actual number is probably lower. More tornadoes will probably occur before the end of the year.
Tornadoes have occurred in Missouri in March (including the infamous Tri- State tornado) but the chances of encountering a tornado are low.
Yes. Every tornado is a vortex from beginning to end.
A funnel with the narrow end of the funnel pointed downward.
No. While global warming might affect tornado activity, tornadoes themselves are an end product of weather and climatic activity, not a cause.
There is no official beginning or end to tornado season, but it is generally considered to end in June. However, tornadoes are not limited to tornado season, it's just a time of higher tornado activity. Strong tornadoes can and have happened at all times of the year.
The duration of a tornado can vary considerably. Most tornadoes last less than five minutes, but major tornadoes can easily last half an hour to an hour. A handful of tornadoes have lasted for more than three hours. At the other end, some tornadoes last only a few seconds.
The total number is not known. There were 201 recorded tornadoes in the United States in 1950, but at the time, the vast majority of F0 and F1 tornadoes were missed. These account for about 90% of tornadoes today. So the actual number of tornadoes in 1950 was, without a doubt, much higher. Based on modern percentages we can estimate that the United States probably had between 750 and 1150 tornadoes in 1950, more likely near the higher end of that range.
Tornadoes usually occur in spring and early summer while hurricanes usually occur in summer and early fall. However, tornadoes can occur at any time of year, and out of season hurricanes have occurred as well.
