COMMENT:A successful weather modification technique used by the Soviets to reduce hail
damage inflicted on major economical crops, involves the use of WHIFF and FIRE WHEEL
Radars in conjuction with 100MM AA Guns, KS-19. After a hail cloud is detected by radar,
the AA guns have 2 minutes in which to fire cartridges containing a crystallizing reagent
needed to preclude the arrival of damaging hail. The guns are maintained at centralized
locations and only dispatched to their respective firing sites (two guns per site, each
covering a radius of lOkm) when there is a threat of inclement weather. A station will
maintain approximately 13 - 40 AA guns. These weather modification stations have been
