The photo above was taken near Memphis, Tennessee in early August of this year. At any given moment, there are roughly 2,000 thunderstorms in progress around the world. Essentially, a thunderstorm is a mechanism or process that removes heat and moisture near the Earth's surface and transports it to the upper levels of the atmosphere. By-products of this process include clouds, precipitation (rain and hail), and wind (updrafts and downdrafts. The building cumulonimbus clouds of this storm are highlighted by a setting Sun.
