Meaning and Definition
A small-scale rotating weather system, typically between 2 and 10 kilometres in diameter, found within larger convective storms.
In meteorology, a vortex of air on the mesoscale of atmospheric motion, often associated with and embedded within mesoscale convective systems (MCS) like squall lines or supercell thunderstorms. They can intensify rainfall, cause damaging winds, and sometimes spawn tornadoes.

Common Mistakes When Using “mesovortex”

- Confusing it with a 'mesocyclone', which is a larger, parent rotation in a supercell thunderstorm.
- Using it in non-meteorological contexts.
FAQ
Frequently Asked Questions
No. A mesovortex is a broader rotation within a storm. A tornado is a violently rotating column of air in contact with the ground. A mesovortex can sometimes spawn or intensify a tornado, but they are distinct phenomena.
In British English: /ˈmɛsəʊˌvɔːtɛks/ (MEZ-oh-VOR-teks). In American English: /ˈmɛzoʊˌvɔːrtɛks/ (MEZ-oh-VOR-teks). The main difference is the vowel in the second syllable ('oh' vs. 'ow').
Almost certainly not. They would use more accessible terms like 'small-scale rotation', 'spin', or 'circulation within the storm' to communicate the risk to the general public.
Both are mesoscale rotations. A mesocyclone is typically larger (3-10 km) and is the defining, persistent rotation of a supercell thunderstorm. A mesovortex is often smaller (2-5 km) and can form within various types of convective systems, not just supercells, and may be shorter-lived.
A small-scale rotating weather system, typically between 2 and 10 kilometres in diameter, found within larger convective storms.
Mesovortex is usually technical/scientific in register.

Memory Aids
Mnemonic
Think of 'MESO' as 'middle-sized' (like the Mesozoic era was the middle age of dinosaurs) and 'VORTEX' as a whirlpool. A mesovortex is a middle-sized whirlpool of air inside a big storm.
Conceptual Metaphor
A whirlpool or eddy within a larger river of storm clouds.
