A storm consisting of thunder and lightning produced by a cumulonimbus, usually accompanied with rain or hail. A more severe thunderstorm can cause mesocyclones
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: cumulus stage, mature stage, and dissipation stage
a storm resulting from strong rising air currents; heavy rain or hail along with thunder and lightning
Local storm resulting from warm humid air rising in an unstable environment Air may start moving upward because of unequal surface heating, the lifting of warm air along a frontal zone, or diverging upper-level winds (these diverging winds draw air up beneath them) The scattered thunderstorms that develop in the summer are called air-mass thunderstorms because they form in warm, maritime tropical air masses away from other weather fronts More violent severe thunderstorms form in areas with a strong vertical wind shear that forces the updraft into the mature stage, the most intense stage of the thunderstorm Severe thunderstorms can produce large hail, forceful winds, flash floods, and tornadoes
A storm with lightning and thunder, produced by a cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail
(TS, TSRA, TSTM) - A shower accompanied by thunder It is always accompanied by lightning and thunder, and occasionally by strong gusty winds, hail, and or heavy rain
a local storm produced by a cumulonimbus cloud and accompanied by lightning and thunder
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 thunderstorm is a storm in which there is thunder and lightning and a lot of heavy rain. a storm with thunder and lightning. Violent, short-lived atmospheric disturbance, almost always associated with cumulonimbus clouds (very tall, dense rain clouds) and accompanied by thunder and lightning. Such storms usually generate strong, gusty winds and heavy rain, and occasionally hail or tornadoes. Thunderstorms have been known to occur in almost every part of the world, although they are rare in the polar regions. In the U.S. the areas of maximum thunderstorm activity are the Florida peninsula and the coast of the Gulf of Mexico (70-80 days per year)
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
Produced by a cumulonimbus cloud, it is a storm 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
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 local storm that's accompanied by thunder and lightning A severe thunderstorm comes with damaging winds and gusts to more than 60-80 kph, heavy rain and possibly hailstones, frequent lightning and occasionally a tornado They're most prevalent from late May to early September Southern Ontario receives the most thunderstorms (about 30-35 per year), while the Northwest Territories experiences the fewest (two to three storms per year)
n A spectacular symphony of nature in which rolling thunder complements streaks of lightning against dark and majestic clouds, droplets pour forth to clean the air and make soft ripples in puddles, staining everything a deep and rich shade, the flowers come open and children dance, and civilization dons galoshes and raincoats, muttering about what a bother it is
A rain or snow shower in which there is lightning Thunder is always caused by lightning In general, the upward and downward winds, updrafts and downdrafts, in thunderstorms are more violent than those in ordinary showers
