<p>The process comprises spreading in space, separately and in different zones, AgI and a powder compsn. based on micronised urea. The AgI is spread continuously over a certain period and when it is complete, the urea compsn. is spread in an instantaneous manner. A rocket for the seeding comprises a tubular body with an interior propellant and ignition appts., with a nose which is exploded by a charge beneath its lower part. The AgI is incorporated in the propellant and the urea compsn. in the nose. The process is used for forming rain, increasing the amt. of rain. preventing hail and for dispersing cloud.</p> |
