Tornadoes are the proct of thunderstorms in the clouds. Specifically, a tornado is a small part of the huge energy thunderstorms in small area on a form of release. The formation of a tornado can be divided into four stages:
(1) the instability of the atmosphere has the intense updraft, because the biggest transit the airflow rapids influence, it was further strengthened.(2) in the vertical direction with speed and direction are the wind shear interaction, the increased flow of the troposphere in central begin to spin, form the mesoscale cyclone.(3) with the mesoscale cyclones and up to the surface development stretch, it is thinner and increase. At the same time, a small area of the enhanced auxiliary close, that is born dragon roll in formed within the cyclone

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. Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and st. Most tornadoes have wind speeds less than 110 miles per hour (177 km/h), are about 250 feet (76 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (483 km/h), stretch more than two miles (3.2 km) across, and stay on the ground for dozens of miles (more than 100 km).[2][3][4]
