What is a Thunderstorm?
A thunderstorm, often referred to as an electrical or lightning storm, is defined by the occurrence of lightning and the sound it creates, known as thunder. Weaker versions of these storms are sometimes called thundershowers.
Thunderstorms form within a specific type of cloud called cumulonimbus. They typically bring strong winds and can lead to heavy rainfall, as well as occasional snow, sleet, or hail. |
However, some thunderstorms may produce little to no precipitation. These storms can align in a series or create a rain band, which is known as a squall line.
Severe thunderstorms are among the most hazardous weather events, capable of producing large hail, intense winds, and tornadoes. |
The most intense of these storms, called supercells, exhibit a rotating structure similar to cyclones. While most thunderstorms generally follow the prevailing wind patterns in the troposphere, vertical wind shear can sometimes cause them to change direction at a right angle to the wind shear.
