Sudden electrical discharges manifested by a flash of light (lightning) and a sharp rumbling sound. Thunderstorms are associated with convective clouds (Cumulonimbus) and are more often accompanied by precipitation. They are usually shortlived and hit on only a small area.
Convective showers which produce lightning. Heavy rain, strong winds and hail are all possible in thunderstorms.
A weather phenomenon known to haunt outdoorsmen, particularly when tent camping, or just fishing a long distance from base camp. Accompanying winds frequently strike terror into people asleep in tents or navigating four-foot swells on a large lake with islands and hidden rock outcroppings. Mental effects can be lingering.
Localized storm producing lightning and thunder, often associated with a passing cold front.
a storm resulting from strong rising air currents; heavy rain or hail along with thunder and lightning
a an electrical storm with lightning (flashes of bright light), which creates thunder (very loud sounds)
a form of severe weather involving lightning and thunder
a heat engine, that draws moist air into an updraft where it evaporates and releases more heat, which causes more updraft, and so on
a localized storm cloud producing thunder, lightning and often gusty winds, heavy rain and hail
a really big cloud that can ruin
a severe storm several kilometres in diameter created by the rapid lifting of moist warm air which creates a cumulonimbus cloud and which may include lightning, thunder, heavy rain, or hail
a storm containing lighting caused by unstable atmospheric conditions
a storm containing lightning caused by
a storm that produces lightning and thunder, and occurs in cumulonimbus clouds
a type of storm that generates lightning and the attendant thunder
a very turbulent environment, with strong updrafts that transport water droplets up in the cloud, while ice particles descend from the frozen upper regions
a violent atmospheric disturbance accompanied by lightning, thunder, heavy rain, strong gusts of wind, and (occasionally) by hail
A violent weather system that produces gusty winds, lightning, and heavy rain. Thunderstorms occur along fronts where air is rapidly rising.
A local storm produced by a cumulonimbus cloud always accompanied with thunder and lightning with strong gusts of wind, heavy rain and sometimes with hail. Thunderstorms can build to 40-50,000 feet in height and higher in the tropics. Only the stability of the stratosphere limits their upward growth. Reported as light, moderate or heavy upon predetermined factors. They can produce tornadoes when certain other weather criteria are met in the atmosphere.
One or more sudden electrical discharges manifested by a flash of light(lightning) and a sharp or rumbling sound(thunder). It is regarded to have ceased when no further thunder is heard in 10-15 minutes after the last audible thunder.
A local storm produced by cumulonimbus clouds. Always accompanied by lightning and thunder.
An atmospheric process involving particularly vigorous convection of humid, warm air. Such air stores energy not just as heat but also through its humidity, and as it rises and gets rid of its water by producing rain, the latter form of energy gives it extra heating and helps it rise even higher, to the base of the stratosphere, where the thunderstorm flattens out. As the rising air cools, some droplets freeze, and collision of frozen droplets carried in the rising air with larger ones dropping due to gravity leads to lightning.
A storm in which thunder and bolts of lightning occur.
A storm with lightning and thunder, produced by a cumulonimbus cloud, and usually associated with gusty winds, heavy rain, and sometimes hail and tornadoes.
A local storm (accompanied by lightning and thunder) produced by a cumulonimbus cloud, usually with gusty winds, heavy rain, and sometimes hail. Non-severe thunderstorms rarely have lifetimes over two hours. A typical, non-severe thunderstorm life cycle consists of three stages: (1) CUMULUS STAGE-- warm, moist air rises (updraft) and condenses into tiny water droplets which make up the visible cloud. (2) MATURE STAGE-- the cloud grows above the freezing level; precipitation forms and becomes heavy enough to fall back to earth. This precipitation generates cool air which also sinks back to earth with the precipitation. (3) DISSIPATION STAGE-- Cool rain and downdraft spread throughout the storm replacing the updraft which is the lifeblood of the thunderstorm. The visible cumulonimbus cloud becomes softer in appearance, less distinctly outlined or "fuzzy" and dissipates, sometimes leaving only the high anvil cloud, as the storm rains itself out.
a local storm produced by a cumulonimbus cloud, always with lightning and thunder, and usually accompanied by strong gusts of wind, heavy rain, and sometimes hail
is a local storm resulting from rising warm humid air, which produces lightning and therefore thunder, usually accompanied by rain or hail, gusty winds, and strong vertical air motion.
A storm that produces lightning and thunder and often heavy rain and strong wind. When the weather is hazy, hot, and humid, thunderstorms are likely to develop.
A cumulonimbus cloud producing lightning and thunder. May also produce heavy rain, hail, and strong gusty winds.
a brief electrical storm usu. accompanied by heavy rain and high winds.
A local storm, usually produced by a cumulonimbus cloud, and always accompanied by thunder and lightning.
A local storm, invariably produced in a cumulonimbus cloud, and always accompanied by lightning and thunder.
Intense, local convectional storm associated with a cumulonimbus cloud and yielding heavy precipitation, along with lightning and thunder.
In general, a local storm produced by a cumulonimbus cloud, and accompanied by lightning and thunder, usually with strong wind gusts, heavy rain and sometimes hail. A cumulonimbus cloud is a cauliflower-shaped cloud that has a height taller than or equal to its width.
Produced by a cumulonimbus cloud, it is a microscale event of relatively short duration characterized by thunder, lightning, gusty surface winds, turbulence, hail, icing, precipitation, moderate to extreme up and downdrafts, and under the most severe conditions, tornadoes.
Rain, hail or snow shower accompanied by flashes of lightning from a Cb cloud.
A storm several kilometers in diameter created by the rapid lifting of moist warm air which creates a cumulonimbus cloud. Thunderstorms can have the following severe weather associated with them: strong winds; hail; lightning; tornadoes; thunder; and heavy rain.
A localized storm, invariably produced by a cumulonimbus cloud (CB), accompanied by lightning and thunder. Synonym - Electrical Storm.
A thunderstorm, also called an electrical storm, is a form of weather characterized by the presence of lightning and its attendant thunder produced from a cumulonimbus cloud. Thunderstorms are usually accompanied by heavy rainfall and they can also be accompanied by strong winds, hail and tornadoes. In the winter months, snowfall can occasionally take place in a thunderstorm.
