This is the upward movement of air in a thunderstorm, which gives the storm fuel (energy).
convection
low pressure system
updraft
downdraft
This is the downward movement of air in a thunderstorm, this releases energy from the storm.
convection
high pressure system
updraft
downdraft
This stage of thunderstorm development is the most dangerous where strong updrafts and downdrafts coexist.
Developing cumulus stage
Mature stage
Dissipating stage
Back stage
In this stage of thunderstorm formation, the updraft is cut off by the downdraft, and the storm no longer has the fuel needed to sustain itself.
Towering cumulus stage
Mature cumulus stage
Dissipating stage
Front stage
