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 .

At the small end, it includes storm-scale phenomena (the size of an individual thunderstorm [1]). Examples of mesoscale weather systems are sea breezes , squall lines , and mesoscale convective complexes .
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 ...
Vertical cross-section through a supercell showing the BWER. The bounded weak echo region, also known as a BWER or a vault, is a radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which extends upward into, and is surrounded by higher reflectivities aloft, forming a kind of dome of weak echoes.
Buoyant convection begins at the level of free convection (LFC), above which an air parcel may ascend through the free convective layer (FCL) with positive buoyancy. Its buoyancy turns negative at the equilibrium level (EL) , but the parcel's vertical momentum may carry it to the maximum parcel level (MPL) where the negative buoyancy ...
A mesoscale convective complex (MCC) is a unique kind of mesoscale convective system which is defined by characteristics observed in infrared satellite imagery. They are long-lived, often form nocturnally, and commonly contain heavy rainfall , wind , hail , lightning , and possibly tornadoes .
A narrow cold-frontal rainband (NCFR) is a characteristic of particularly sharp cold frontal boundaries. These can usually be seen very easily on satellite photos. NCFRs are typically accompanied by strong gusty winds and brief but intense rainfall. Convection may or may not occur depending on the stability of the air mass being lifted by the ...
