Fog And Cloud Dispersal
The techniques of cloud seeding can also be used for a second purpose, the removal of clouds and fog. This goal is desirable, as an example, in regions around an airport where prolonged fog can bring air travel to a halt, at great economic cost. The use of dry ice as a seeding agent can cause water droplets in fog to condense on ice crystals, after which they precipitate out of the air. In the process, fog banks and clouds may disappear.
Some dramatic results have been achieved with commercial fog dispersion at airports. In some cases, areas of a few square kilometers have been cleared in a matter of hours by seeding with dry ice.
