A tornado is a column of spinning air. They usually form in very turbulent storm systems known as super cells. Basically they can form when a storm starts to rotate and snake down from the cloud. Sometimes tornadoes can snake up from the ground to connect with the cloud. These are known as Non-descending tornadoes. They are classed by the now Enhanced Fujita Scale that assesses the damage done to different types of structures. They are rated from F0 (light damage) to an F5 (incredible damage).
If you live in a tornado prone area, you should be aware of what a tornado watch and tornado warning is. A tornado watch means that the weather conditions are right to form tornadoes, and tornado warning means that a tornado has been seen on the ground and could be heading in your direction.

A tornado in central Oklahoma. The tornado itself is the thin tube reaching from the cloud to the ground. The lower half of this tornado is surrounded by a translucent dust cloud, kicked up by the tornado's strong winds at the surface.

A tornado is a violently rotating column of air which is in contact with both a cumulonimbus (or, in rare cases, cumulus) cloud base and the surface of the earth. Tornadoes can come in many sizes, but are typically in the form of a visible condensation funnel, with the narrow end touching the earth. Often, a cloud of debris encircles the lower portion of the funnel.
Most tornadoes have winds of 110 mph (175 km/h) or less, are approximately 250 feet (75 meters) across, and travel a few miles (several kilometers) before dissipating. However, some tornadoes can have winds of more than 300 mph (480 km/h), be more than a mile (1.6 km) across, and stay on the ground for dozens of miles (more than 100 kilometers).[1][2][3]
Tornadoes have been observed on every continent except Antarctica; however, most of the world's tornadoes occur in the United States.[4] Other areas which commonly experience tornadoes include New Zealand, western and southeastern Australia, south-central Canada, northwestern and central Europe, Italy, south-central and eastern Asia, east-central South America, and Southern Africa.[5]

-occur more frequently in the U.S. than in any other country around the world.
-in an average year, 800 tornadoes are reported nationwide usually totally 80 deaths and 1500 injuries.
-they can reach up to 250 MPH or more
-once a tornado in Broken Bow, Oklahoma, carried a motel sign 30 miles and dropped it in Arkansas!
-of all tornadoes, 2% of them are violent tornadoes
-it usually hails during a tornado and can reach the size of grapefruit!!!

A violent spinning funnel shaped vortex of wind that is born from storm clouds that suck up wind currents and rotate them at such speeds that when the tip of the funnel touches ground it can blow freight trains off the tracks and literally flatten every object in its path. This violence lasts only a few minutes, but leaves death and devastation in the path it cuts thru. The only really safe place to be is underground or in a deep trench as it skips along the ground surface like a dancing devil. A violent, frightening quirk of nature.

Well I can tell you its not a freak of nature, they occur with a tremendous amount of frequency in certain parts of the country. Its cause or they can happen when two weather systems collide, one warm weather cell, and one cold. They create a condition that promotes spinning of those two weather events and sometimes those vortex's come down to the ground forming a tornado.

A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters or cyclones,[1] although the word cyclone is used in meteorology, in a wider sense, to name any closed low pressure circulation.
