Cloud Seeding

Triggers rain.

The role of wind in pollination is well known, but now scientists discovered another role for wind in triggering rain.

During cloud formation water can become supercooled, that is, it can get below freezing point but remain not frozen. This stage is so unstable that we can add some catalyst molecules to trigger rain. Historically humans used silver iodide, frozen carbon dioxide and some salts to trigger rain. This is known as cloud seeding.

Cloud Seeding
Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation that falls from clouds by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practised in airports, where harsh weather conditions are experienced.


However nature uses different material to seed the clouds. Nature uses both sea salt and land dust to trigger rain. Wind at the surface of the seas causes waves to roll. Those waves release aerosols into the air carrying the sea salt. The wind carries both the sea salt and the land dust to the clouds. The sea salt and land dust cause the supercooled water to coalesce and trigger precipitation. This was known recently, however 1400 years before it was discovered this was portrayed in the Quran:

Quran 15:22
And We sent the seeding winds, then cause the rain to descend from the sky, and gave you water to drink, though you are not the guardians of its stores.

٢٢ وَأَرْسَلْنَا الرِّيَاحَ لَوَاقِحَ فَأَنْزَلْنَا مِنَ السَّمَاءِ مَاءً فَأَسْقَيْنَاكُمُوهُ وَمَا أَنْتُمْ لَهُ بِخَازِنِينَ

For centuries it was thought that this was the role of wind in pollination but now we know that this is the role of wind in cloud seeding.


How could an illiterate man who lived 1400 years ago have known about cloud seeding? 


The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
