Supercell - Wikipedia
Diagram of supercell from above. RFD: rear flank downdraft, FFD: front flank downdraft, V: V-notch, U: Main Updraft, I: Updraft/Downdraft Interface, H: hook echo. This is generally the area of heaviest and most widespread precipitation.
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.
Mesocyclone - Wikipedia
Supercell diagram with the mesocyclone rotation in red. A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation (vortex), typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms.
Thunderstorm - Supercell, Wind, Hail | Britannica
Oct 12, 2024 · Thunderstorm - Supercell, Wind, Hail: When environmental winds are favourable, the updraft and downdraft of a storm become organized and twist around and reinforce each other. The result is a long-lived supercell storm. These storms are the most intense type of thunderstorm.

Understanding the Three Types of Supercell Thunderstorms
Jan 6, 2024 · Determining the type of supercells that may occur within a given severe weather environment is important for a multitude of reasons. A supercell is a thunderstorm that rotates. There are three types of supercells: low-precipitation (LP), …
The four types of thunderstorms - Spectrum News
Jun 16, 2020 · What sets the supercell apart is its rotating updraft, which can significantly prolong the life of the storm and cause it to become very organized. This rotation is due to the shear, or a change in wind direction and/or speed with height.
SUPERCELLS - NOAA/NWS Storm Prediction Center
Supercells are storms --- usually, but not necessarily, thunderstorms --- that contain updrafts that rotate about a vertical axis. This rotation is derived from shear in the environmental wind field (that is, a change in wind direction and / or speed with height) surrounding the storm as …

Supercell Thunderstorms - an introduction to their structure
Supercells are indeed impressive storms, generating hail, damaging winds, and tornadoes. Supercells are unique in that the storms updraft rotates. This rotating updraft is called a mesocyclone. How does the mesocyclone form within a supercell?
