Mesoscale convective vortex, also known as MCV, is a weather phenomenon that occurs during thunderstorm activity. It is a small-scale circulation that can intensify a storm's updrafts, leading to heavy rainfall and strong winds. Other synonyms for MCV include "mesovortex" and "MCS vortex," which refer specifically to the vortex's association with a mesoscale convective system. Other broader terms for this type of phenomenon include "mesocyclone" and "rotating thunderstorm." Understanding these terms can help meteorologists and weather enthusiasts better track and predict the behavior of severe weather events.
