The typical enhancement of rainfall and updraft motion in
deep cumulus and
cumulonimbus clouds within heavy raining meso - scale disturbance areas acts to increase the return flow mass subsidence in the surrounding broader clear and partly cloudy regions (Figure 8).
This is a large - eddy simulation of a
deep cumulonimbus (a tall rain
cloud).
The observations showed that when the usual shallow cumulus
clouds give way to the MJO's towering
cumulonimbus storms, radiant heat trapped by
clouds and moisture gradually warms a
deeper column of the lower atmosphere while the tops of the storms radiate heat into space, cooling the upper troposphere.
The warm water evaporates from the ocean surface, and the light, warm and humid air rises, leading to
deep convection in the form of towering
cumulonimbus clouds and heavy precipitation.
