Tornadoes have been known to strip asphalt pavement. When winds vary in speed or direction at different altitudes a condition known as wind shear - the updraft will start to spin. Large temperature differences are associated with early winter cold fronts that move rapidly across the country from the north and west, at times spawning widespread outbreaks of small tornadoes. Tornadoes are caused by the interaction of weather systems, which create large thunderstorms (the most powerful and long-lived type is called a supercell). "Tornado Alley," a region that includes the area in the eastern state of South Dakota, Nebraska, Kansas, Oklahoma, northern Texas, and eastern Colorado, is often home to the most powerful and destructive of these storms. Tornadoes form when warm, humid air collides with cold, dry air. (c) When a cold front moves into an area with warm, moist air, it can create the conditions needed for a tornado to form.

Most Southern Hemisphere tornadoes occur in Australia. April 2011 set the U.S. record for the most tornadoes in any month. Tornadoes form in unusually violent thunderstorms when there is sufficient (1) instability and (2) wind shear present in the lower atmosphere. How is it that a violent whirlwind can form in a cloud and then reach to the ground and make splinters and chaos of everything in its path? IE reveals this too. All these measurements affect how likely the cloud is to produce a tornado. They do not connect with any cloud-base rotation and are not tornadoes, but because gustnadoes often have a spinning dust cloud at ground level, they are sometimes wrongly reported as tornadoes.
