Supercell Thunderstorms thunderstorms with deep rotating updrafts
The last of the four major storm types is the supercell. We define a supercell as a thunderstorm with a deep rotating updraft (mesocyclone).
Supercell thunderstorms are sometimes classified by meteorologists and storm spotters into three categories.
supercell"An often dangerous convective storm that consists primarily of a single, quasi-steady rotating updraft, ...
A persistent, single, intense updraught and downdraught coexisting in a thunderstorm.

Supercell (or Supercell Storm) - a violent thunderstorm which can produce hail and large tornadoes and containing updrafts and downdrafts that are nearly in balance, allowing it to maintain itself for several hours ...
Supercell - A thunderstorm with a persistent rotating updraft. Supercells are rare, but are responsible for a remarkably high percentage of severe weather events - especially tornadoes, extremely large hail and damaging straight-line winds.
Supercell - A relatively long-lived thunderstorm with a persistent rotating updraft.
SUPERCELL A severe thunderstorm characterized by a rotating, long-lived, intense updraft.
Supercell storm An enormous severe thunderstorm whose updrafts and downdrafts are nearly in balance, allowing it to maintain itself for several hours. It can produce large hail and tornadoes.
SUPERCELL- A storm with a strong, tilted and rotating updraft due to good instability and wind shear in the troposphere. Most of the strong tornadoes and large hail occur with supercells.
SUPERCELL- A highly organized thunderstorm with a rotating updraft, known as a mesocyclone. It poses an inordinately high threat to life and property. Often produces large hail, strong winds, and tornadoes.
Supercell thunderstorm A relatively long-lived, large and intense cell characterized by an exceptionally strong updraft; may produce a tornado.
Potentially the most dangerous of the convective storm types.
Supercell Thunderstorm- A severe thunderstorm whose updrafts and downdrafts are in near balance allowing the storm to maintain itself for several hours. Supercells often produce large hail and tornadoes.
Classic Supercell - See supercell.
Clear Slot - A local region of clearing skies or reduced cloud cover, indicating an intrusion of drier air; often seen as a bright area with higher cloud bases on the west or southwest side of a wall cloud.
Classic Supercell See supercell.
Clear Ice It is a glossy, clear or translucent ice formed by the relatively slow freezing of large supercooled droplets.
Supercell Thunderstorm- An unusually violent thunderstorm that is capable of generating tornadoes.
Subsidence- The descent of a body of air, usually in a high pressure area, that warms the lower levels of air.
Supercell - A severe thunderstorm whose updrafts and downdrafts are in near balance for several hours. Supercells often produce large hail and tornadoes.
Temperature - The measurement of how hot or cold something is.
SUPERCELL - A highly organized thunderstorm with a single, and very powerful updraft. The speed of this updraft is very high, sometimes 150 MPH, and is accompanied by persistent rotation on a broad scale.
LP supercell thunderstorms often have a small updraft base as seen in this thunderstorm near Hart, Texas.

>> Supercell thunderstorms: In some ways, this can be regarded as a special case of the multi-cell storm, with some additional factors.
Severe supercell development is most likely in an environment possessing great buoyancy (CAPE) and large vertical wind shear. A Bulk Richardson Number of between 15 and 35 favor supercell development.

LP Storm (or LP Supercell) - Low-Precipitation storm (or Low-Precipitation supercell): A supercell thunderstorm characterized by a relative lack of visible precipitation.
See a supercell for an example. SHEAR It is the rate of change over a short duration. In wind shear, it can refer to the frequent change in wind speed within a short distance. It can occur vertically, such as a change with height, or horizontally.
Transverse rolls are one type of transverse band, and often indicate an environment favorable for the subsequent development of supercells.
Flanking LineA line of cumulus or towering cumulus clouds connected to and extending outward from the most active part of a supercell, normally on the southwest side.
Supercell thunderstorms often exhibit inflow notches, usually in the right quadrant of a classic supercell, but sometimes in the eastern part of an HP storm or in the rear part of a storm (rear inflow notch).
Four Basic Thunderstorm Types Thunderstorms occur in a variety of forms, sometimes as an isolated cumulonimbus cloud (anvil shaped), sometimes as a cluster of clouds, sometimes as a squall line, and sometimes as a supercell (massive convective ...
A horizontal, tail-shaped cloud (not a funnel cloud) at low levels extending from the precipitation cascade region of a supercell toward the wall cloud (i.e., it usually is observed extending from the wall cloud toward the north or northeast).
Most summer severe weather events, including damaging tornadoes, are spawned by a special type of thunderstorm known as a supercell.
Incus (Latin = anvil): the anvil of a large CB, particularly a multicell or supercell storm, which has spread out, usually when upper-level winds are light.
Whereas tornadoes (picture) are always connected to a thunderstorm's (or supercell's) cloudbase, commonly known as wall cloud.
In the central plains of the United States they are most frequent in spring during the late afternoon. See also supercell tornado, nonsupercell tornado, gustnado, landspout, waterspout. 2.
A area of rotation of storm size that may often be found on the southwest part of a supercell. Its circulation can be larger than the tornado that may develop within it, but not necessarily.
Right Mover - A thunderstorm that moves appreciably to the right relative to the main steering winds and to other nearby thunderstorms. Right movers typically are associated with a high potential for severe weather. (Supercells often are right ...
Tstorms: Supercells to 60K ft. & may last 24 hr. 35. Tstorms: Tornadoes: South West side of Severe Thunderstorm. 36. Tstorms: Training Effect: One after another moving in the same direction. 37.
