While tornadoes can occur all year long, tornado season in Texas runs from March through August. During these months, it is not uncommon for several tornadoes to occur at once.Continue Reading
The way tornadoes form is not completely understood, but scientists believe they begin when wind shear causes thunderstorms to rotate. As the winds rotate faster, a funnel cloud is formed, and if this cloud reaches the ground, it is called a tornado.
Tornadoes are classified according to the Fujita scale, developed by Dr. Tetsuya Fujita in 1971. The scale ranges from an F0 tornado, with winds less than 73 miles per hour, to an F5, with winds of 261-318 miles per hour.
If a tornado approaches, take shelter in a basement or a room on the lowest floor of the house — preferably one without windows. Cover yourself with a blanket or mattress, if possible, and remain there until the tornado passes.Learn more about Storms
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 >
Tornadoes are also called twisters, and the wind speed of extreme tornadoes can reach up to 300 miles per hour. The United States averages 1,200 tornadoes each year, which is more than any other country. Tornadoes that take place above water are called waterspouts. Most tornadoes occur in a region called Tornado Alley; Kansas, Oklahoma, Texas and Florida are U.S. states where tornadoes occur most often.Full Answer >
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.Full Answer >
Fire tornadoes form when combustible gases ignite in windy conditions. According to the Mother Nature Network, most fire tornadoes spawn from wildfires. The center of a fire tornado is a column of flaming gas up to 9 feet in diameter. A whirling column of fresh air circulates around the fiery core, feeding it fresh oxygen and sustaining the blaze.Full Answer >
