Most tornadoes are created as a result of thunderstorms that form at the meeting point between humid air from the Gulf of Mexico and dry, cooler air from Canada. At that point, instability occurs in the atmosphere, and altering wind directions and a boost in speed makes for a spinning in the lower part of the atmosphere. When rising air makes the rotation vertical, creating a circle that can be as wide as 6 miles, the stage is set for tornadoes to start forming.Know More
Not every thunderstorm turns into a tornado, fortunately. There has to be enough moisture at the lower levels of the atmosphere for the storm to be strong, and a triggering event, such as a cold front or other confluence of winds, is also necessary to hold that moist air. After the air starts rising and finds saturation, it keeps going to make a thunderstorm cloud. As the air goes up, if it cools dramatically, instability begins to increase. If the winds are moving in a clockwise direction, tornadoes are more likely.
If one notices a funnel cloud starting to form, it is the beginning of a tornado. Seeking shelter is definitely the best course of action if there is a tornado warning.Learn more about Storms
Thunderstorms and tornadoes are related because tornadoes always form out of thunderstorms. Specifically, tornadoes develop when there's a steady upward flow of warm air, which is generally lower in pressure than cool air.Full Answer >
Stormy weather is associated with heavy rain, hurricanes, tornadoes, typhoons, hail, sleet, tropical cyclones and general thunderstorms. Atmospheric instability is one of the causes of stormy weather, as well as high pressure zones moving in from certain directions. For example, a high pressure zone from the north causes colder weather as winter approaches and a high pressure zone from the south brings warm weather.Full Answer >
Tornado season varies depending on location, but most tornadoes appear during April, May and June. In the United States, southeastern regions tend to suffer the most tornado activity from February to April, while incidences of tornadoes in the northern Plains increase during the months of June through August.Full Answer >
All tornadoes are possible of causing damage to structural buildings and human life, explains ECoffeeOnline.com. Some tornadoes, depending on their size, cause catastrophic damage and major loss of lives. A large tornado moves at a high speed, levels everything in its path, throws vehicles on the road and sends debris flying at an incredibly high speed through the air.Full Answer >
