Cloud Fertilization Technology

Our present knowledge regarding artificial increase of precipitation has a definition as follows: application of appropriate fertility materials at the right time and place that makes changes in clouds, so that clouds behave in a different and predictable way and satisfying results are achieved. The technology of cloud fertilization is developed with the aim of providing the means and facilities for achieving this kind of interference in cloud processes and thus uses scientific considerations in its implementation. According to our knowledge, nature produces rain in very diverse cloud conditions through two different major processes, and if we seek useful results, the technology mentioned above should be applied with the exact knowledge of real and natural processes. On the other hand, the current state of the physics of clouds is such that at best it can provide guidelines, rather than detailed instructions, for implementation of technology in accordance with different cloud conditions. Compared to some of the existing approaches to cloud modification, which require "engineering", this scientific effort is the main branch of ongoing research activities. It is better to admit that the principles of technology discussed in the following have relatively limited scientific bases, and their implementation is only carried out in the light of a clear understanding of the ambiguities that still need to be explained. Cloud fertilization technology includes two important components: 1- Application of suitable fertility strategies. 2- Fertilizing materials’ production technology.
