IPA: /ˈsuːpərˌsɛl/
KK: /ˈsuːpərˌsɛl/
A type of severe thunderstorm that has a rotating updraft, which allows it to last for a long time and can produce dangerous weather like large hail and tornadoes.
The meteorologist warned that a supercell was forming in the area, which could lead to severe weather conditions.
Supercell → It is formed from "super-" (meaning above or beyond) and "cell" (from Latin "cella", meaning a small room or chamber). The word "supercell" refers to a type of thunderstorm characterized by a rotating updraft, which can be seen as a chamber of intense weather activity above typical storm levels.
Think of something that is 'above' ('super-') a regular 'chamber' or 'room' ('cell') — that's why a supercell is a powerful storm that forms in an elevated weather chamber.
