Weather Modification - Storm Prevention

Storm Prevention

Project Stormfury was an attempt to weaken tropical cyclones by flying aircraft into storms and seeding the eyewall with silver iodide. The project was run by the United States Government from 1962 to 1983. A similar project using soot was run in 1958, with inconclusive results. Various methods have been proposed to reduce the harmful effects of hurricanes. Moshe Alamaro of the Massachusetts Institute of Technology proposed using barges with upward-pointing jet engines to trigger smaller storms to disrupt the progress of an incoming hurricane; critics doubt the jets would be powerful enough to make any noticeable difference.

Alexandre Chorin of the University of California, Berkeley, proposed dropping large amounts of environmentally friendly oils on the sea surface to prevent droplet formation. Experiments by Kerry Emanuel of MIT in 2002 suggested that hurricane-force winds would disrupt the oil slick, making it ineffective. Other scientists disputed the factual basis of the theoretical mechanism assumed by this approach. The Florida company Dyn-O-Mat proposes the use of a product it has developed, called Dyn-O-Gel, to reduce the strength of hurricanes. The substance is a polymer in powder form which reportedly has the ability to absorb 1,500 times its own weight in water. The theory is that the polymer is dropped into clouds to remove their moisture and force the storm to use more energy to move the heavier water drops, thus helping to dissipate the storm. When the gel reaches the ocean surface, it is reportedly dissolved. The company has tested the substance on a thunderstorm, but there has not been any scientific consensus established as to its effectiveness.

Hail cannons have been used by some farmers since the 19th century in an attempt to ward off hail, but there is no reliable scientific evidence to confirm their effectiveness. Another new anti-hurricane technology is a method for the reduction of tropical cyclones’ destructive force - pumping sea water into and diffusing it in the wind at the bottom of such tropical cyclone in its eyewall.
