Weather modification – Avoiding floods by “cloud seeding”, Indonesia

weather-modification-avoiding-floods-by-cloud-seeding-indonesia

Cloud seeding, a weather modification technique, is commonly used to encourage rainfall in arid regions by dispersing substances into the air. But Indonesian government is using it to avoid further floods by redirecting rain to the ocean and claims their attempt has been successful.

cloud seeding Cloud seeding, a form of weather modification, is the attempt 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 practiced in airports.
The most common chemicals used for cloud seeding include silver iodide and dry ice (solid carbon dioxide). Credit: Wiki

 

Indonesian scientists speculated that inducing clouds over ocean before they reach Jakarta will prevent further flooding of the city. Following government orders, military planes carrying tonnes of salt began the cloud seeding operation scattering salt onto rain clouds across the ocean. Tri Handoko Seto, a top official of the Weather Modification Technical Unit of the Agency for the Assessment and Application of Technology, told SciDev.Net,

“We are mimicking nature. It is easy to make rain in most clouds above the sea. We found out that salt from sea water, which evaporates from the sea, accelerates the rain process because it encourages the cloud particles to adsorb water.”

During recent years, Indonesia has repeatedly faced deadly floods and landslides, causing losses of lives and property. 32 people had died and 46,000 were forced to flee due to floods in Jakarta this January, more deaths were registered in February.

Government claims their attempt has been fruitful as heavy rain and flooding predicted by meteorologists from January 26-29 onward was tamed. Yet skeptics say it doesn’t prove most clouds didn’t reach mainland because of the experiment – maybe the rain wouldn’t have reached Jakarta anyway. However, Seto says,

“We have conducted an evaluation using the data in our radar device, which records cloud development and movement. From our analysis, cloud seeding contributed to the decrease of rainfall in Jakarta during this period.”

This cloud seeding operation is expected to continue for another month during the rainy season.

  1. Mike215 – So glad to know I am not the only one who thinks the same thing. I looked at it as, The Mississippi was so low last summer 12' below norm – that the big businesses lost so much revenue transporting less goods on a one way river and via RR that they wanted to make sure that didn't happen this year- hence all the rain and snow! But they don't care about whipping peoples' lives off the maps doing this!!!!

  2. Cloud seeding can create massive floods as the ones we have seen in Colorado. Government scientists claim that cloud seeding cannot create floods, but we see that in the past it was classified as a weapon of mass destruction by the US Air force and the United Nations.
    During the Vietnam War the US Air Forced sprayed thousands of tons of silver iodine over SE Asia under Project Popeye (see google) creating massive floods and destruction. After the war the US was accused of committing war crimes and was forced to sign a treaty banning the use of this weapon is war. The treaty can be found on google: CONVENTION ON THE PROHIBITION OF MILITARY OR ANY OTHER HOSTILE USE OF ENVIRONMENTAL MODIFICATION TECHNIQUES.
    The cost of this flood is at least $2 billion and counting and massive lawsuit against the state are coming. The state will claim that cloud seeding is an innocent way to increase the amount of snow. But juries are not that stupid.

  3. this strikes me as an odd idea, i’d say pushing rain clowds from the land into rainclowds comming from the sea will make for a bad day? not sure how the geomagnetics of that would make for something more livable than before, since you’re only injecting more energy into the system, drifting further from equilibrium.
