A thunderstorm, as the name suggests, is a violent weather disturbance accompanied by lightning/thunder and severe storm. It is also known as an electrical storm or a lightning storm or hurricane. According to news there is a severe thunderstorm warning in Fairfax County of Northern Virginia, USA.

The Earth’s atmosphere changes during the occurrence of this storm and is characterized by heavy rainfall, dense clouds and lightning, alongwith loud, audible thunderous effects. 


HOW DO THUNDERSTORMS FORM?

Thunderstorms originate when warm, wet air rises in a massive, quick air stream to cooler areas of the atmosphere, forming layers of warm, moist air. The liquid in the air stream condenses there, forming massive cumulonimbus clouds and, eventually, precipitation. Cooled air columns then fall to the ground, causing severe downdrafts and horizontal winds. 

Electrical charges build up on cloud particles at the same time (water droplets and ice). Lightning strikes when the electric charge in the atmosphere builds up to a very high level. Lightning heats the air it passes through so rapidly and strongly that shock waves are emitted, that are heard as thunderclaps and rolls. 

They can sometimes be accompanied by swirling air vortices that become concentrated and powerful enough to give rise to tornadoes.
