Supercell - Wikipedia
Mammatus (Mamma, Mammatocumulus) are bulbous or pillow-like cloud formations extending from beneath the anvil of a thunderstorm. These clouds form as cold air in the anvil region of a storm sinks into warmer air beneath it.
What is a Supercell? - National Weather Service
What makes a supercell unique from all other thunderstorm types is that it contains a deep and persistent rotating updraft called a mesocyclone. If the environment is favorable, supercell thunderstorms can last for several hours.

Wall clouds form when warm, moist inflow meets the cool, moist outflow from the forward flanking downdraft. The convergence of these two moist airflows are ingested in the updraft resulting in a low cloud formation.
In intense supercells, mid-level mesocyclone becomes strong enough to wrap precipitation around to backside of updraft, creating a characteristic pendant or hook echo. Low-level mesocyclone (from which a tornado can form) is located within notch of hook.
Supercell storm clouds act like atmospheric mountains
Sep 9, 2021 · These high-flying clouds have been linked to high winds, hailstorms, and tornadoes on the ground. To find out why, researchers combined lightning data, radar, and severe storm warnings to build a 3D visualization of AACPs.
SUPERCELLS - NOAA/NWS Storm Prediction Center
The striations of the low-level clouds reflect, in part, converging low-level winds (green and yellow arrows) curving into the rotating updraft of the storm. This rotating updraft is known as a mesocyclone .
Types of Thunderstorms - National Oceanic and Atmospheric Administration
May 9, 2023 · Beneath the supercell, the rotation of the storm is often visible as well, appearing as a lowered, rotating cloud, called a Wall Cloud, formed below the rain-free base and/or below the main storm tower updraft. Wall clouds are often …

You should also be able to describe the cloud formation (a wall cloud) that's often a precursor to a funnel cloud or tornado formation, and identify the location on radar reflectivity where a tornado might form in a classic supercell.
Thunderstorm Development & The Evolution of Supercells
With its base at or slightly above the CCL, the cloud is dominated by updrafts as it grows toward its equilibrium level. As increasingly low-level moisture is pumped into the growing cumulus, the relatively large liquid hydrometeors begin to form in its upper regions.
Understanding Supercells - Definition, Formation, Types and …
Oct 23, 2024 · The formation of a supercell is a complex process that depends on specific atmospheric conditions and dynamic interactions. Ample moisture in the lower and middle layers of the atmosphere is crucial, as it provides the necessary fuel for cloud and storm formation.
