Mesoscale Convective
Systems
qClusters of
severe thunderstorms are called mesoscale
convective
systems (MCSs).
q MCSs occur as squall lines, or as circular
clusters called mesoscale
convective complex’s (MCCs).
qIndividual
storms develop in concert in a situation which propagates additional thunderstorms.
qMany MCSs
have life spans from up to 12 hrs to several days.
qSevere
thunderstorms may also form from individual supercells which contain only one updraft (supercells
may also be a
part of an MCS).
