Tornado (tornado read woven Arnedo) as the storm caused by the rotation of the air. Can occur in various forms. The most common style is characteristic cone. By the end of the cone pointing down to the ground. Tornadoes can cause damage even higher. The wind speed can be as high as 500 km / h (300 mi / h), which caused the collapse of the building was
caused by tornadoes, wind, heat and cold air come together and form a whirlwind. And when the wind is not constant. Make one end down to touch the ground, causing a tornado. Is mainly caused by a tornado in the United States. The terrain can cause hot air and cold collision area plains tornado into the level is destroyed and wind speed divided by F0 - F5 by F0 is the tornado that weak real and F5, a tornado is. extreme level classification of the Private Make Manado is based Fujita scale, which requires that each class has a strong storm the storm F0 64-116 kilometers per hour wind speeds 117-180 mph winds, storm F1 F2 storm winds. 181-253 kilometers per hour wind speeds 254-332 mph storm F3 F4 storm wind speeds 333-418 mph wind speeds 419-512 mph storm F5 from the survey showed that for every 1,000 tornadoes. to be the F0 of approximately 389 times, the F1 approximately 356 times, the F2 approximately 194 times, the F3 of about 49 times, the F4 approximately 11 times and F5 of approximately 1 times the strength of the storm affect. size, and the dissolution of the storm with hurricane-level F0-F1 may have a diameter of up to 100 meters, and moved a few kilometers to disintegrate while the storm F5 may have a diameter of more than 1,600 meters, and moved on. More than 100 miles before it decays. The higher the level, the storm will cause a storm is big and slow decay with the March 18, 1925 in the United States. Tornadoes concurrent 9-ball is F2 2 balls, F3 and 4 children, F4 2 balls and F5 1 ball moving landslides, Missouri, Illinois, Indiana, Kentucky, Tennessee, Alabama, and New. Kansas has killed more than 747 people, of whom only a single ball that F5 storm. Killing people to 695 people, the death toll from the storm more than 8 children together only 50 people, only the storm that occurred as the F5 tornado that killed most in history. USA Science Damage to life and property is worth more than the current 1,862 million.
