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
Low-level storm features are visually identified by a well-defined wall cloud, a rain free base, a rear flank downdraft, and distinctly separate updraft and downdraft regions. Classic supercells are most com-monly found in the Great Plains of the United States and can be relatively isolated.
•Wall cloud: A lowering, rotating cloud base where humid rain-cooled air from downdraft is drawn into updraft. An indication of low-level mesocyclone from which tornado drops

In HP (High Precipitation) supercells precipitation often surrounds the updraft, and may hide it completely. They can have a wall cloud, but it may also be obscured by the heavy precipitation. Also, as these storms produce blinding precipitation, damaging winds and large hail, your visibility of any tornadoes may be obscured.
Understanding the Three Types of Supercell Thunderstorms
Jan 6, 2024 · A supercell is a thunderstorm that rotates. There are three types of supercells: low-precipitation (LP), classic, and high-precipitation (HP). The configuration of the wind shear profiles within a severe weather environment is critical in diagnosing what types of supercells can be expected on a given day.
Supercells: What to Know About These Dangerous Thunderstorms
May 6, 2024 · HP supercells contain heavier concentrations of rain and hail. The precipitation can sometimes obscure the storm's structure, including wall clouds and tornadoes. Tornadoes obscured by heavy...

The storm is rotating counter-clockwise (red arrows), which is typical for most long-lived supercells in the Northern Hemisphere. The striations of the low-level clouds reflect, in part, converging low-level winds (green and yellow arrows) curving into the …

Aug 22, 2019 · The wall cloud (also murus or pedestal cloud) is a pronounced lowering in a supercell’s rain-free base. It forms as rain-cooled air from both the RFD and FFD is pulled upward (entrained) with the warmer inflow air into the updraft.

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 …
