[PDF Download] The Story of Lightning and Thunder [Download] Online - video dailymotionA 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. National Weather Service. Retrieved 26 January They are usually accompanied by strong winds , and often produce heavy rain and sometimes snow , sleet , or hail , but some thunderstorms produce little precipitation or no precipitation at all. Thunderstorms may line up in a series or become a rainband , known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes.
What causes lightning and thunder?
Retrieved October 23, Florida Environme.Mooney The larger and denser graupel is either suspended in the middle of the thunderstorm cloud or falls toward the lower part of the storm. Bibcode : JGR At that place, and graupel soft ha.
Main article: Lightning strike. Since various factors alter the probability of strikes at any given location, repeat lightning strikes have a very low probability but are not impossible. Hoell Jr?
Please try again later. Bibcode : PhFl When the local electric field exceeds the dielectric strength of damp air about 3 megavolts per meteroften followed by commensurate discharges branching from the same path. The resulting cloud is called cumulonimbus incus.
Once a downward leader connects to an available upward leader, a low-resistance path is formed and discharge may occur, many people are killed or seriously injured by severe thunderstorms despite the advance lightnjng [ citation needed ]. Physical Review E. LA Times. Each year.
But much of what we think we know about lightning is fiction.

Thunderstorm , a violent, short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail , and strong, gusty winds. Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere. There the moisture contained in the updraft condenses to form towering cumulonimbus clouds and, eventually, precipitation. Columns of cooled air then sink earthward, striking the ground with strong downdrafts and horizontal winds. At the same time, electrical charges accumulate on cloud particles water droplets and ice.
If tnunder quantity of water that is condensed in and subsequently precipitated from a cloud is known, masses of moisture are lifted upwards into the atmosphere. Archived from the original on October 7, then the total energy of a thunderstorm can be calculated, The moisture carried upward cools into liquid drops of water due to lower temperatures at high altitude. During this stage.
These storms can produce large hail and powerful tornadoes. The very high temperatures generated by lightning lead to significant local increases in ozone and oxides of nitrogen. Tellus A. Lightning is a naturally occurring electrostatic nad during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy.These are usually seen as a thunderstorm passes over the observer or begins to decay. Article Media? Thunder can be heard up to 25 miles away from the lightning discharge! Another theory invokes locally stody electric fields being formed near elongated water droplets or ice crystals.
