Thunderstorm

A Thunderstorm is defined as a short-lived and violent weather disturbance that is always associated with the lightning effect, thunder, dense clouds, and heavy raining effects. When the layer of warm moist air is raised and gets cooler in the atmosphere then it`s known as a thunderstorm. In the atmosphere, the moisture updraft and it condenses and forms cumulonimbus clouds, which eventually precipitate. The columns of cold air come towards the earth and strike the ground with strong downdraft and strong horizontal winds. The electrical charges accumulate on the clouds at the same time. When the accumulated electrical charge becomes sufficiently large, lightning discharges. 
Shock waves are produced when the lightning heats the air through it, very intensely. These shock waves are heard as rolls of thunder or clapes. On occasions, the thunderstorm causes strong tornadoes also. 
Thunderstorms occur almost in every region in this world. However, in the polar regions, they are rare and infrequent at latitude higher than 50 degrees North and 50 degrees South latitude. Therefore the most prone area to thunderstorms in the temperate and tropical regions. The Florida peninsula is the area in the U.S.A where maximum thunderstorms occur, more than 90 thunderstorms per year. 
Large areas of ascending and descending air cause violent disturbance in earth`s wind system: thunderstorms are not expected to follow these patterns. Technically thunderstorms occur when the atmosphere becomes unstable to vertical motion. Such instability arises when light and warm air is overlain with the cold air. The cooler air sinks under such conditions the cooler air sinks, which raises the warmer air upward. If a sufficient amount of air raises upward, an updrift will be produced. The water will condense and form clouds when the updrift is moist, and the condensation process will create latent heat energy, further increasing the instability.
