The method of hail interruption near protected area, based on preliminary impact hails cloud and hails cloudy systems
The Central Caucasus is one of the regions which located in area of grate hail dangerous. Every year we lose from 5 to 7 % of yield after hailstorm. Sometimes the level of damage reaches 18 %. For prevention of damage was started special manufacturing activity in 1967. For it used competition method and acceleration of formation of rainfall. Despite the reached progress in borders of this region was found out that annually the level of deterioration of yield after hailstorms is rising. The reason is: existing methods of impact on hail processes are not able to interrupt the catastrophic hail near protected area. The method for interrupting hail from cloud and clouds systems, based on the preliminary impact hail clouds and clouds systems offering. This method has been pilot-tested in the Stavropol uniformed services on active impact on meteorological and other geophysical processes in 2004-2008. The average efficiency of the proposed method was 96,7 % (after testing on an independent physical material). This method can be recommended for anti-hail protection services, planning and working on artificial rain enhancement.
