Convective storm detection is the meteorological observation, and short-term prediction, of deep moist convection (DMC). DMC describes atmospheric conditions producing single or clusters of large vertical extension clouds ranging from cumulus congestus to cumulonimbus , the latter producing thunderstorms associated with lightning and thunder .
A mesoscale convective complex has either an area of cloud top of 100,000 km 2 or greater with temperature less than or equal to −32 °C, or an area of cloud top of 50,000 km 2 with temperature less than or equal to −52 °C. Size definitions must be met for 6 hours or greater.
A mesocyclone is a type of mesovortex, approximately 1 to 10 km (0.6 to 6 mi) in diameter (the mesoscale of meteorology), within a convective storm. [6] Mesocyclones are air that rises and rotates around a vertical axis, usually in the same direction as low pressure systems in a given hemisphere.
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. Their area of cold cloud tops exceeds 100,000 square kilometres (39,000 sq mi) with temperature less than or equal to −32 °C (−26 °F); and an area of cloud top of 50,000 square ...
The Storm Prediction Center began asking for public comment on proposed categorical additions to the Day 1-3 Convective Outlooks on April 21, 2014, for a two-month period. [24] The Storm Prediction Center broadened this system beginning on October 22, 2014 by adding two new risk categories to the three used originally.
Atmospheric convection is the result of a parcel-environment instability (temperature difference layer) in the atmosphere. [ jargon ] Different lapse rates within dry and moist air masses lead to instability.

Radar schematic of a LEWP. This shape is a single wave along the pattern, for real LEWPs this shape is tessellated repeatedly in a linear fashion. A line echo wave pattern (LEWP) is a weather radar formation in which a single line of thunderstorms presenting multiple bow echoes forms south (or equatorward) of a mesoscale low-pressure area with a rotating "head".
