The regulation of quantity of precipitation on the present moment depending on a situation can be realized by two ways: by use crystallization reagents; by use hygroscopic reagents. Also a combination of these methods can be used, when one of the influence instrument contains hygroscopic and crystallization reagents. With help of this method it is possible to destroy a cloud (suitable to influence) by making it rain or snow. On the average it makes *0 **0 - *0 **0 tons of water during one influence. The principle of action of crystallization reagent consists in formation of the large amount of artificial crystallization centers inside the cloud. As a result it leads to occurrence of precipitations or, in exclusive cases, to realization of the phenomenon of super crystallization, when entire cloud of super cooled liquid becomes crystallized, so the formation of precipitation in traditional way becomes impossible. However, the process of super crystallization needs an excessive charge of reagent, therefore it is used as an instrument of reduction of precipitations quantity only in special cases. Generally much simpler methods are used to destruct a cloud on its way to protected territory. Though the technologies of this type are most examined, unfortunately their applicability is limited only to cold clouds, because the given mechanism can be realized at temperatures below minus 3C.
