One kind of rain cloud is the cumulonimbus cloud associated with
thunderstorms. Meteorologists have studied how cumulonimbus clouds
are formed and how they produce rain, hail, and lightning. They
have found that cumulonimbus cloud go through the following steps
to produce rain:
1) The clouds are pushed by the wind: Cumulonimbus clouds begin
to form when wind pushes some small pieces of clouds (cumulus)
to an area where these clouds converge.
2) Joining: Then the small clouds join together forming a larger
cloud.
3) Stacking: When the small clouds join together, updrafts within
the larger cloud increase. The updrafts near the center of the
cloud are stronger than those near the edges. These updrafts cause
the cloud body to grow vertically, so the cloud is stacked up.
This vertical growth causes the cloud body to stretch into cooler
regions of the atmosphere where drops of water and hail formulate
and begin to grow larger and larger. When these drops of water
and hail become too heavy for the updrafts to support them, they
begin to fall from the cloud as rain, hail, etc.
Allah said in the Quran:
Have you not seen how Allah makes the
clouds move gently, then joins them together, then makes them
into a stack, and then you see the rain come out of it...?
[Al-Quran
24:43]
Meteorologists have only recently come to know of these details
of cloud formation, structure, and function by using advanced
equipment like planes, satellites, computers, balloons which the
Quran had already told us 1400 years ago.
