The purpose of this research was to introduce the theoretical foundations of fertilizing the clouds. First, the importance of the fertility issue is presented and then the origin of Cloud Condensation Nuclei (CCN), natural Ice Nuclei (IN), types of fertility, mechanisms of growth of cloud droplets and the factor of fertility have been discussed.
The results of the study show that human beings can help the nature in terms of the number and type of precipitation formation nuclei through the process of cloud fertilizing. According to the rules of cloud physics, the fertilization of clouds is possible. Using cloud artificial insemination technology, it is possible to produce ultrafine silver iodide particles or other materials that can play the same role as natural ice crystals (freezing cores) and thus accelerate the mechanism of the Bergeron process and consequently increase precipitation.
