Supercells and Tornadoes * - The strongest and most damaging tornadoes from within supercells. This is one of the primary reasons why researchers strive to understand them better. They want to be able to predict them (e.g. left figure) more accurately.
    .   .

Nonsupercell Tornadoes * - Even though supercell thunderstorms are responsible for the biggest and deadliest tornadoes, a significant number of tornadoes form under nonsupercell clouds and storms.
    .   .

Tornadoes * - Tornadoes, cyclic storms and low-level flow fields associated with tornadic thunderstorms.
    .   .

Tornadoes * - The last severe weather element is the tornado. Defined as a violently rotating column of air in contact with the ground and pendent from a cumulonimbus cloud, tornadoes are capable of inflicting extreme damage.
    .   .

Tornadic Supercell * - This supercell did produce tornadoes, six of them. About the time this photograph was taken, the last of the six tornadoes was occurring. From this vantage point about 20 miles north of the storm, near Itasca, Texas, we see a small portion of the rain-fr...

Tornadoes * - With technology in its current state, forecasters can give residents in the path of hurricanes advanced warnings to help prevent casualties due to storm surge, strong winds, and heavy rain, -- each of which claimed many lives during the first half of the...

Wall Clouds Beneath CB Towers * - Here we have a southward view of a supercell, with precipitation in the right middle-ground and a wall cloud beneath the cumulonimbus (Cb) tower and anvil overhang in the background. The wall cloud produced a tornado within 30 minutes in southwest Oklaho...

On Radar Images * - Supercells most frequently are isolated and often develop in the warm air ahead of a squall line. This supercell formed south-southwest of the radar site and produced large hail and tornadoes well ahead of a broken to solid squall line.
    .   .

Supercells * - Supercells are long-lived thunderstorms which exhibit quasi-steady structure including a rotating updraft. These storms generally produce severe weather including heavy winds, large hail, heavy rainfall, and occasionally tornadoes. In fact it is these su...
