Detailed explanation-1: -The Short Answer: A tornado forms from a large thunderstorm. Inside thunderclouds, warm, humid air rises, while cool air falls–along with rain or hail. These conditions can cause spinning air currents inside the cloud.

Detailed explanation-2: -Rising air within the thunderstorm tilts the rotating air from horizontal to vertical – now the area of rotation extends through much of the storm. Once the updraft is rotating and being fed by warm, moist air flowing in at ground level, a tornado can form.

Detailed explanation-3: -When warm, moist air collides with cold, dry air, tornadoes emerge. Generally, thunderstorms form when cooler, denser air is pushed over warmer air which is the cause of tornadoes. Updrafts are caused by warm air rising through the cold air. Whenever the wind strength or direction changes, the updraft begins to rotate.

Detailed explanation-4: -Tornadoes are outgrowths of powerful thunderstorms that appear as rotating, funnel-shaped clouds. They extend from a thunderstorm to the ground with violent winds that average 30 miles per hour.
