The physical basis for precipitation enhancement, hail suppression and fog dissipation could be summarized as follows:

The basic concept of precipitation enhancement is that supercooled clouds, that is, those clouds that contain liquid droplets at temperatures colder than 0° Celsius, also contain large amounts of supercooled water.

This is evident from aircraft icing as well as measurements from research aircraft. It has been observed that large amounts of supercooled water in such clouds are not converted to precipitation.

This unconverted supercooled water can be thought of as an untapped reservoir of water in the natural cloud system.
