Air mass with up and down drafts in consecutive loops as a single entity From Wikipedia, the free encyclopedia
A storm cell is an air mass that contains up and down drafts in convective loops and that moves and reacts as a single entity, functioning as the smallest unit of a storm-producing system. An organized grouping of thunder clouds will thus be considered as a series of storm cells with their up/downdrafts being independent or interfering one with the other.[1]
A storm cell can extend over an area the size of a few tens of square miles/kilometers and last 30 minutes or so.[2] When the updraft and the environmental wind shear is well coordinated, the size and the duration of the cell can be much greater leading to a supercell.[2] Finally, storm cells can form on the outflow of previous cells leading to multicellular thunderstorms or mesoscale convective systems. Slow motion of these more intense storm cells or groups of cells can produce large precipitation accumulations and flash flood, or other dangerous phenomena like hail and tornadoes.[3]
One can distinguish three stages in the evolution of a thunderstorm cell:[2][3]
