Patent No: US 2550324A Process for controlling weather

This invention relates to a process for effecting . changes in weather conditions and more specifically to a process for dissipating clouds and fog by clearing the atmosphere of moisture particles that are large enough to be visible and yet not large enough to fall out of suspension in the gases of the atmosphere. The overall object of the present invention is directed to the control of - Weather conditions generally. Specifically, an object of this invention is to maintain contact weather conditions at air ports, air traffic Zones and centers and on air ways by reducing economically the amount of visible water vapor causing the particular undesirable Weather. Another object of this invention is to control Weather which causes hail damage, lightning and interference with wave transmissions by the reduction of visible water vapor through the dissipation of cumulonimbus clouds.
