Effectiveness of Hail Control in Serbia

Djuro Radinović

Abstract


The artificial modification of hail formation in the SR of Serbia has been orgainized and operating according to principles similar to those developed in the U.S.S.R.  The hail control system in Serbia covers about 4 million hectares of agricultural surface, which is one of the largest connected areas protected by such a system in the world.  After a period of 17 years of continuous operation an evaluation of its effectiveness has been made. This evaluation is based on the statistics of the size of hail-swept areas, percentage of the damaged crops and the frequencies of hail occurrences observed in the regular network of meteorological stations. The size reduction of hail-swept areas in protected territory show a decrease of an estimated 63% when compared to unprotected territory. A 22% reduction in hail frequency is suggested by the data analysis according to observations at meteorological stations.
