The Life Stages of Individual Cells in Thunderstorms
The stages of life of individual cells in thunderstorms progress from the Cumulus Stage with powerful updrafts, to the Mature Stage where precipitation forms, and finally to the Dissipating Stage as downdrafts weaken. Air Mass Thunderstorms are described as non-frontal and typically form in warm, mo
