Development of Methods of Active Influence on the Processes of Precipitation Formation in Clouds in Order to Solve Environmental and Economic Problems

The paper discusses some approaches to the development of methods of active influence on clouds, which develop in the High-Mountain geophysical institute. We considered the problems of determination in the cloud the region in which to make the particles of the reactants, concentration of these particles, the beginning and completion of seeding. Such questions should be solved on the basis of numerical modeling of clouds. The most common approach to the development of methods of active influence on clouds is a simulation of different variants of any particles of reagent in the cloud and choose the most effective one from the point of view of achieving the objectives of impact compared to a natural development of the cloud. Another approach to the development of the method of sedimentation control in the clouds is to consider this problem in the framework of optimal control theory. Despite the difficulties in implementing this approach, it is very effective and produces optimal results.
