text: (Abbreviated MCC.) A subset of mesoscale convective systems (MCS) that exhibit a large, circular (as observed by satellite), long-lived, cold cloud shield.

The cold cloud shield must exhibit the following physical characteristics.

    Size: A - Cloud shield with continuously low infrared (IR) temperature ≤ -32°C must have an area ≥ 105 km2; and B - Interior cold cloud region with temperature ≤ -52°C must have an area ≥ 0.5 X 105 km2.
    Initiate: Size definitions A and B are first satisfied
    Duration: Size definitions A and B must be met for a period ≥ 6 h.
    Maximum extent: Contiguous cold cloud shield (IR temperature ≤ -33°C) reaches maximum size.
    Shape: Eccentricity (minor axis/major axis) ≥ 0.7 at time of maximum extent.
    Terminate: Size definitions A and B no longer satisfied.

    Alternatively, a dynamical definition of an MCC requires that the system have a Rossby number of order 1 and exhibit a horizontal scale comparable to the Rossby radius of deformation. In midlatitude MCS environments, the Rossby radius of deformation is about 300 km.
