http://bio-ice.forumotion.com/behavior-of-ice-nucleators-in-the-clouds-f1/-t1.htm How do ice nucleators affect cloud processes? Different approaches are used to evaluate this effect: modeling, experimentation and reasoning based on theory. One of the questions in everyone's minds is how they affect snow and rainfall.

But testing this link is difficult because there still seems to be much uncertainty about what the mechanism actually is, what triggers it and how prevalent it is. In temperate climates rain is initiated by ice nucleation (in thunderstorms it is a mix of this and droplet coalescence). But ice nuclei are rare. Typically there are 0.1-20/L active at -15°C ...

An airplane equipped with a burner emitting silver-iodide nuclei was flying under cloud base. By updrafts the silver iodide is injected into higher elevations where ice particls form on the nuclei. The growing ice crystals then fall through the cloud layers with supercooled droplets. Those droplets then attach to the ice crytals by impaction freezing forming snow flakes and graupel which melts when falling through the ...

I suggest that you read the article posted on 24 Jan 2006 on the blog "Pruned" entitled "Meteorological Alchemy". Read about cloud farms, etc. It's worth visiting for the incredible pictures of saucer-shaped clouds trapped on mountain tops. http://pruned.blogspot.com/2006_01_01_archive.html Cindy Morris 23 ...
