Physical Basis and Concepts in Supercooled Cloud Seeding

Since understanding of the physical basis of cloud seeding is one of the most necessary elements in successful weather modification research, therefore in this paper the physical basis and concepts related to supercooled cloud seeding has been presented. In this regard, at first, a short review on precipitation process in cold cloud seeding, reasons of difference in cold precipitation processes has been presented. Then the conceptual models of statical cloud seeding for convective and winter orographic clouds and dynamical cloud seeding has been discussed and in other section, microphysical-dynamical interactions processes in supercooled cloud seeding using Liquid Carbon Dioxide has been explained, and finally the methods of optimization of seeding effects has been presented.
