• Thunderstorm: a mesoscale weather system produced by vigorous convection that reach to great altitudes within the troposphere. ... A thunderstorm consists of one or more convection cells accompanied by lightning and thunder and, often, locally heavy rainfall (or snowfall), and gusty surface winds. ...
• A thunderstorm cell typically completes its life cycle in 30 minutes to an hour, but sometimes lightning, thunder, and bursts of heavy rain persists many hours. This is because each thunderstorm cell may be at different stage in its life cycle. A thunderstorm may track in a different direction than the individual cells.
• Cumulus stage is the initial stage of a thunderstorm in which a cumulus cloud undergoes vertical and horizontal development reaching up to 8 to 10 km (5 to 6 mi. ...
• Mature stage is the middle and the most intense stage of a thunderstorm in which a convective cloud undergoes further vertical development with tops exceeding 18 km (11 mi. ...
• Gust front (mesoscale cold front): the leading edge of a mass of relatively cool air that flow out of base of a thunderstorm and spreads along the ground well in advance of the parent thunderstorm cell. An uplift along the gust front may trigger formation of secondary thunderstorm cell tens of kilometers ahead of the parent cell.
• Dissipating stage is the last stage of a thunderstorm in which precipitation spreads throughout the convective cell over a period of 30 minutes. ...
• It is one of the continuous process thoughout the life cycle of a thunderstorm.
• Air mass thunderstorm develops almost randomly within a mass of maritime tropical air. ...
• Frontal thunderstorm is associated with lifting of air along the surface of a front, usually along or ahead of a cold front. ...
• Thunderstorms are most common over the continental interiors of tropical latitudes such as steamy Amazon Basin of Brazil, the Congo Basin of equatorial Africa, and the islands of Indonesia that experience thunderstorm activity at least 100 days.
• Central Florida, which experiences more 90 thunderstorm days due to sea-breeze circulation, is the most frequent thunderstorm site in North America. The regions east of the Rocky mountains that subject to intense temperature gradient arising from variations in topography, have more than 60 thunderstorm days on average.

•  Thunderstorm Rotation and Tornado Formation.
•   Warm moist air is lighter than the cold dry air making for a strong updraft within the thunderstorm. ...
• On the outside of the thunderstorm rotation might be visible as in this photo and here. ...   Most of our information about the inside of a tornado-generating thunderstorm comes from data gathered by Doppler radar.   The illustration below would be an example of how a tornado would typically form in this type of thunderstorm. ...
• What makes a tornadic thunderstorm more severe than an ordinary thunderstorm?.
• In your everyday thunderstorm you have the warm moist air rising causing updrafts within the storm, and colder air descending causing downdrafts.   Typically these thunderstorm downdrafts will be separate from the downdrafts caused by the rain falling. ...   As an ordinary thunderstorm matures the falling rain cause more down drafts, and finally begins to negatively affect the updraft that builds the storm.   This would cause a typical thunderstorm to weaken, less updraft, less power. ...
• But in a severe thunderstorm the downdrafts may be so strong that they pull the moisture or falling rain into them further strengthening the down drafts. ...
•             In a severe thunderstorm the down drafts and updrafts actually feed each other giving the storm a life of its own.   Whereas an ordinary thunderstorm might only last 30 minutes to an hour a severe thunderstorm self generates its life so that it may last several hours or more. ...   So when the National Weather Service issues a severe thunderstorm watch or warning, be on the lookout for down drafts, they can be dangerous.
•             Besides dangerous downdrafts and powerful updrafts, a severe thunderstorm usually is acted on by strong wind sheer, winds changing speed and direction with height. ... Putting all these ingredients together makes for a dangerous thunderstorm.

• We define a supercell as a thunderstorm with a deep rotating updraft (mesocyclone). ...
• The flanking line of the supercell behaves differently than that of the multicell cluster storm, in that updraft elements usually merge into the main rotating updraft and then explode vertically, rather than develop into separate and competing thunderstorm cells. ...

• Thunderstorm.
• A thunderstorm is a form of severe weather characterized by the presence of lightning and its attendant thunder. ...
• A given cell of a thunderstorm typically goes through three stages: the cumulus stage, the mature stage, and the dissipation stage. ...
• In the cumulus stage of a thunderstorm cell, masses of moisture are pushed upwards; the moisture rapidly cools into liquid drops of water vapor, which appears as cumulus clouds. ... This creates a low-pressure zone beneath the forming thunderstorm. In a typical thunderstorm, some 5E8kg of water vapor are lifted and the amount of energy released when this condenses is about equal to the energy used by a city (US-2002) of 100,000 over a month. ...
• The single cell thunderstorm is the typical three-stage situation as described above, usually lasting about 30 minutes from the start of significant precipitation. ...
• In a multicellular storm, several of these thunderstorm cells merge into a larger system. ... The storm itself will have different portions sequentually going through the various thunderstorm stages. ...
• When conditions are right, several multicell systems may merge into large "thunderstorm convective complexes" stretching for hundreds of miles; in the presence of cyclones or upper-level troughs, even larger clusters of thunderstorms may cover thousands of miles. ...
