A thunderstorm is a storm with heavy rainfall accompanied by wind, thunder and lightning. These storms occur when air that is moist and close to the ground heats up and rises to form cumulonimbus clouds that produce precipitation. Electrical charges develop near the bottom of the clouds, resulting i


Thunderstorms are formed by the combination of three main ingredients: moisture, unstable atmospheric air and an external acting force making the damp and volatile air rise upward. Thunderstorms come in several different categories, which are orographic, air mass and frontal. They form above land an


Thunderstorms need three elements in order to form. One of these elements is moisture. The second element is rapidly rising, warm and unstable air. The third element is lifting, commonly produced from fronts and mountains.


Thunderstorms form when rapidly rising warm air brings moisture to higher parts of the atmosphere, then water vapor cools and condenses into droplets that fall to the Earth as rain. The process of rising warm air is called convection, which occurs when the atmosphere above the surface of the planet


Uganda is the country that has the most thunderstorms. The northern Lake Victoria of Kampala in Uganda experiences the maximum number of thunderstorms, at 242 days per year on average, compared to any other country in the world.


Thunderstorms usually last for 30 minutes to an hour. They can happen in a singular fashion, in lines or in clusters. Some of the most dangerous thunderstorms happen when a single storm strikes in a location for a lengthy period of time.


According to the National Severe Storms Laboratory, thunderstorms occur most frequently in temperate climates where warm, moist air encounters pockets of cool air. The four categories of thunderstorms are single-cell storms, multi-cell storms, multi-cell storm lines and supercell thunderstorms. A cl


According to the Weather Channel, the worst thunderstorm in the U.S. in terms of cost took place on May 5, 1995 in Fort Worth, Texas. Hail damage alone was over $2 billion, not counting wind or rain damages. Prior to this, only hurricanes had damage figures in the billions.


Meteorologists use the Lifted Index (LI) to estimate the atmosphere's potential to produce severe thunderstorms. The Lifted Index measures the temperature of rising air in the atmosphere to determine the likelihood of a thunderstorm. Satellite imagery is also used to track thunderstorms.


"Isolated thunderstorms" means that indicators predict only one line of storms affecting 10 to 20 percent of the area, according to Aerostorms. Isolated thunderstorms have nothing to do with the intensity of the storm.
