Storm

stormswindstormstorm system
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder.
It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc.

Thundersnow

snowthunder
They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all.
Thundersnow, also known as a winter thunderstorm or a thundersnowstorm, is an unusual kind of thunderstorm with snow falling as the primary precipitation instead of rain.

Squall line

quasi-linear convective systemrain bandbanding
Thunderstorms may line up in a series or become a rainband, known as a squall line.
A squall line or quasi-linear convective system (QLCS) is a line of thunderstorms forming along or ahead of a cold front.

Supercell

supercell thunderstormsupercell thunderstormsforward flank downdraft
Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones.
A supercell is a thunderstorm characterized by the presence of a mesocyclone: a deep, persistently rotating updraft.

Dry thunderstorm

They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all.
A dry thunderstorm or heat storm is a thunderstorm that produces thunder and lightning, but most or all of its precipitation evaporates before reaching the ground.

Hail

hailstormhailstoneshailstone
They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all.
Hail is possible within most thunderstorms as it is produced by cumulonimbus, and within 2 nmi of the parent storm.

Ice pellets

They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all.
Ice pellets are smaller than hailstones which form in thunderstorms rather than in winter, and are different from graupel ("soft hail") which is made of frosty white rime, and from a mixture of rain and snow which is a slushy liquid or semisolid.

Mesoscale convective system

Mesoscale convective systemsconvection-induceddisturbance
Mesoscale convective systems formed by favorable vertical wind shear within the tropics and subtropics can be responsible for the development of hurricanes.
A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more.

Air-mass thunderstorm

single-cellthunderstorms
There are four types of thunderstorms: single-cell, multi-cell cluster, multi-cell lines and supercells.
An air-mass thunderstorm, also called an "ordinary", "single cell", or "garden variety" thunderstorm, is a thunderstorm that is generally weak and usually not severe.

Wind shear

windshearvertical wind shearshear
While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a deviation in their course at a right angle to the wind shear direction.
It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats.

Tropical cyclone

hurricanetropical stormhurricanes
Mesoscale convective systems formed by favorable vertical wind shear within the tropics and subtropics can be responsible for the development of hurricanes.
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain.

Lightning

A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder.
Lightning is a sudden electrostatic discharge that occurs typically during a thunderstorm.

Multicellular thunderstorm

multi-cellmulti-cell clustermulticellular
There are four types of thunderstorms: single-cell, multi-cell cluster, multi-cell lines and supercells.
A multicellular thunderstorm cluster is a thunderstorm that is composed of multiple cells, each being at a different stage in the life cycle of a thunderstorm.

Cloud

Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in a type of cloud known as a cumulonimbus.
However, if the air becomes sufficiently moist and unstable, orographic showers or thunderstorms may appear.

Atmospheric convection

convectionconvectiveconvective activity
The air tends to rise in an updraft through the process of convection (hence the term convective precipitation).
Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world.

Wind

They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all.
It is commonly observed near microbursts and downbursts caused by thunderstorms, weather fronts, areas of locally higher low level winds referred to as low level jets, near mountains, radiation inversions that occur because of clear skies and calm winds, buildings, wind turbines, and sailboats.

Outflow boundary

gust frontoutflow boundariesoutflow
The downdraft hitting the ground creates an outflow boundary.
An outflow boundary, also known as a gust front, is a storm-scale or mesoscale boundary separating thunderstorm-cooled air (outflow) from the surrounding air; similar in effect to a cold front, with passage marked by a wind shift and usually a drop in temperature and a related pressure jump.

Vertical draft

updraftdowndraftdowndrafts
The air tends to rise in an updraft through the process of convection (hence the term convective precipitation). The falling droplets create a downdraft as it pulls cold air with it, and this cold air spreads out at the Earth's surface, occasionally causing strong winds that are commonly associated with thunderstorms.
This movement of large volumes of air, especially when regions of hot, wet air rise, can create large clouds, and is the central source of thunderstorms.

Tornado

Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes.
Since they form from severe thunderstorms and can be far more intense, faster, and longer-lived than fair weather waterspouts, they are more dangerous.

Severe weather

severesevere weather warningsevere-weather
Severe weather in the form of strong straight-line winds can be expected in areas where the squall line itself is in the shape of a bow echo, within the portion of the line that bows out the most.
High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones.

Heat burst

On the back edge of the rain shield associated with mature squall lines, a wake low can form, which is a mesoscale low pressure area that forms behind the mesoscale high pressure system normally present under the rain canopy, which are sometimes associated with a heat burst.
Heat bursts typically occur during night-time and are associated with decaying thunderstorms.

Tornado warning

tornadowarningswarning
Although a funnel cloud or tornado indicates a severe thunderstorm, a tornado warning is issued in place of a severe thunderstorm warning.
A tornado warning (SAME code: TOR) is an alert issued by national weather forecasting agencies to warn the public that severe thunderstorms with tornadoes are imminent or occurring.

Weather front

frontal systemfrontal boundaryfront
Thunderstorms result from the rapid upward movement of warm, moist air, sometimes along a front.
Cold fronts may feature narrow bands of thunderstorms and severe weather, and may on occasion be preceded by squall lines or dry lines.

Cumulonimbus incus

The resulting cloud is called cumulonimbus incus.
It signifies the thunderstorm in its mature stage, succeeding the cumulonimbus calvus stage.

Flash flood

Damage that results from thunderstorms is mainly inflicted by downburst winds, large hailstones, and flash flooding caused by heavy precipitation.
It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields.
