As a supercell grows in size, the vortex in the middle will begin to tilt, siphoning warm air and moisture upward and spewing out cold dry air toward the ground. The updraft of warm air causes the vortex to swell with water vapor, creating a spiraling funnel cloud at its center—the first visible sign that a tornado is brewing.
Tornado Formation of its wall cloud from a Mesocyclone. As the mesocyclone lowers below the cloud base, it begins to take in cool, moist air from the downdraft region of the storm. The convergence of warm air in the updraft and cool air causes a rotating wall cloud to form.
A tornado can form in a thunderstorm where the rotating air of an updraft (shown in purple) meets the rotating air of a downdraft (shown in aqua), which has turned upward. Tornadoes only form when a thunderstorm has a particular combination of winds.
28 sie 2019 · Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the...

10 paź 2024 · tornado, a small-diameter column of violently rotating air developed within a convective cloud and in contact with the ground. Tornadoes occur most often in association with thunderstorms during the spring and summer in the mid-latitudes of both the Northern and Southern Hemispheres.
The formation and life cycle of tornadoes can be explained in a series of stages: Stage 1 - Storm development. Sun's energy heats the ground which in turn heats the air near ground level....
