What is a thunderstorm?

A thunderstorm is also known as an electrical storm, a lightning storm, or simply a storm with the presence of lightning and thunder.

Thunderstorms typically are produced by cumulonimbus clouds along a frontal boundary and are usually accompanied by strong winds, heavy rain and sometimes snow, hail, or no precipitation at all.

These types of storms may line up in a series known as a squall line.

While most thunderstorms move with the wind flow through the tropospheric layer, vertical wind shear causes a deviation in their course at a right angle to the wind shear direction.

Thunderstorms can generally develop in any geographic location, but most frequently occur in the mid-latitudes.

Thunderstorms are responsible for the development and formation of many severe weather phenomena that can cause damage and death/injury.

There are four types of thunderstorms: single cell, multicell cluster, multicell lines, and supercells.
