Most tornadoes form during supercell thunderstorms, but not all supercell thunderstorms produce tornadoes. Usually, the rotating air near the ground doesn't rotate fast enough for a tornado to form.

If it is in contact with the ground it is a tornado; otherwise it is a funnel cloud. Dust and debris beneath the condensation funnel confirm a tornado's presence. Be careful! Tornadoes can form and be in …

With enough pressure and weight from the downdraft of cool air, the quickening funnel cloud is forced to touch down on the ground, and a tornado is officially born.

There are many types of tornadoes, varying in methods of formation. Despite ongoing scientific study and high-profile research projects such as VORTEX, tornadogenesis remains a complex process, …

Dec 16, 2025 · What causes tornadoes is rooted in supercell thunderstorms, where rotating updrafts produce mesocyclones capable of extreme winds. These storms thrive under high instability and …

Mar 28, 2025 · Tornadoes form by an extreme spinning of air caused by a mixture of heat, humidity and changes in air. Here's how they all come together to create twisters.

Apr 17, 2025 · AccuWeather’s Melissa Constanzer breaks down how tornadoes form. Few weather phenomena capture the imagination—or instill fear—like tornadoes. These swirling columns of wind …

Aug 28, 2019 · Although they can occur at any time of the day or night, most form in the late afternoon. By this time the sun has heated the ground and the atmosphere enough to produce thunderstorms.

So researchers have been investigating triggers for tornadogenesis, such as small-scale downdraft surges and descending precipitation shafts on the supercell’s rear flank, as well as the processes …

Aug 3, 2025 · At their core, tornadoes are rotating columns of air that stretch from a thunderstorm down to the ground. The classic funnel shape is caused by intense wind shear, which means winds …
