Tendencies for the amounts of chemical material used for cloud seeding in Serbia

摘要: Weather modification activities are performed predominantly by cloud seeding. Some operational projects have been for more than half a century and cover planetary scales. These lead to large amount of deposited chemical materials (seeding agents) at the ground level during precipitation. deposits depend on seeding agent. In future, increased amounts agent could be serious problem due various negative effects human environment. Therefore, main intent this paper is determine trends over certain areas Serbia. Four covered Hail Suppression Project in Serbia considered: target area central western Serbia, which well-known hailfall regions. The annual show slow decreasing trend because fewer seedings were last decade century, was economic reasons. contrast, other analysed indicate an increasing induced transfer rockets these difference among small mean its maximum time position as consequence high spatial variability hail. However, sharp that influenced implementation new methodologies, agents delivery tools may also factor projects. given method not only strictly applicable locally applied any scenario area. Dominantly importance weather modifications future will greater ever both positive effects.
