Mesoscale Convective Complex (MCC)

MCCs are very large, persistent and active convective
weather systems that present significant hazard to
aviation. They are capable of producing locally heavy
rainfall, flash floos, tornadoes, hail, high winds and
lightning. They are nearly circular, which distinguishes
them from squall lines.

They have average lifetimes of 12 hours or more and
average diameters of 600 Km.

MCCs have four stages:
    - Genesis
    - Development
    - Maturation
    - Dissipation
