Most importantly, we lack detailed scientific knowledge on the natural production of rain, hail, or snow.

The full potential of rain making will not be realized until we acquire more complete knowledge of natural precipitation processes and refine seeding technology.

About the author Introduction Weather modification is the effort of man to change naturally occurring weather, for the benefit of someone. Raindrops or snowflakes will grow larger by falling through a taller cloud. It would be unthinkable to embark on such a vast experiment before we are able to predict with some certainty what the effects would be.

Improved quantification of these extended extra-area effects is needed to satisfy public concerns and assess hydrologic impacts. Havens, Jiusto, Vonnegut,pp.

Vonnegut choose AgI crystals because there is nearly the same distance between molecules in the crystal lattice for both ice and AgI, which makes AgI the optimum material to nucleate ice.

Some cloud seeding has used smoke containing AgI from generators on the ground to provide nuclei for clouds. First, solving practical problems is made unreasonably difficult, since workers have inadequate knowledge and must guess instead of design. Theory has predicted and experiments are confirming the fact that a few pounds of silver iodide released into the atmosphere in the form of fine particles can exercise a profound influence over the weather hundreds of miles away from the point of release.

Houghton of MIT said: Houghton was exactly correct in calling for more basic scientific research. Vonnegut and Jiusto, together with a reprint of: It is inherently not foreseeable what the benefits of basic scientific research will be.

It is incorrect to frame these contrasting attitudes about publications as professors vs. Any ethical or legal responsibility for the use of information clearly belongs to the user, not the discoverer, of the information. Vonnegut, appearing in before a U.

The drastic decrease in the U.

Among other concerns, it is possible that some unregulated commercial cloud seeding contaminated scientific experiments on cloud seeding. Cotton has clearly explained why such a simple experiment is not adequate. A famous atmospheric physicist wrote in I say "alleged ethical responsibility", as I believe that information is morally neutral, and it is the use of that information that causes benefits or harms.

Without such knowledge, we can not predict the best time and place to seed clouds. A much more reasonable approach lies in continuation of basic research.

Operations that dissipate supercooled fog and low stratus clouds containing water droplets at subfreezing temperatures by seeding with ice-forming agents e. Havens, Jiusto, Vonnegut,p.Prior Park College. One of the UK's largest, co-educational, Catholic, independent senior schools, set in a breathtaking location overlooking the World Heritage city of Bath.

Introduction Weather modification is the effort of man to change naturally occurring weather, for the benefit of someone. The best-known kind of weather modification is cloud seeding, with the goal of producing rain or snow, suppressing hail (which can ruin crops), or weakening hurricanes.

This essay is a companion to my earlier essay, Weather.
