Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to 32 kilometres (20 mi) away. They tend to last 2–4 hours.
Classic-style hook echo of the F5 1999 Bridge Creek-Moore tornado.. A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms.It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity.
They are of greatest concern when contained within severe thunderstorms, since mesocyclones often occur together with updrafts in supercells, within which tornadoes may form near the interchange with a downdraft. Mesocyclones are localized, approximately 2 km (1.2 mi) to 10 km (6.2 mi) in diameter within strong thunderstorms. [2]
The National Weather Service said a few tornadic supercells are expected in the Midwest this weekend. ... It looks like a very tall storm cloud that has an anvil or elongated cloud at the top ...
Supercells are large thunderstorms with deep and persistent rotating updrafts that look like tall storm clouds with anvils or elongated clouds at the top. Friday also looks very windy, with winds ...
Some different supercells for 2D cubic crystal. Both diagonal and non-diagonal supercells presented. In solid-state physics and crystallography, a crystal structure is described by a unit cell repeating periodically over space. There are an infinite number of choices for unit cells, with different shapes and sizes, which can describe the same ...
The ominous eye of Hurricane Milton is visible in stunning detail from outer space in a timeplapse video released Tuesday by NASA.. From 275 miles above Earth, the powerful storm can be seen ...
A bow echo is the characteristic radar return from a mesoscale convective system that is shaped like an archer's bow. These systems can produce severe straight-line winds and occasionally tornadoes, causing major damage. They can also become derechos or form Line echo wave pattern (LEWP).
