The role of the Active Interventions in the atmosphere in the context of climate change

Releasing a significant amount of greenhouse gases into the atmosphere, such as carbon dioxide and methane, we expect to see more severe extreme weather phenomena with harmful effects on society and economic activities. To suppress or mitigate the damages due to extreme weather phenomena, besides framework directives that impose a lowering or complete removal of the greenhouse gases, by interest many programs about active interventions in the atmosphere. These are associated with measures that include hail suppression, rainfall enhancement, fog dissipation, and mitigating the risks associated with early and late frost phenomena. In Romania, the main activity linked by Active Interventions in the Atmosphere by Law 173/2008 is hail suppression by anti-hail rockets technology. In the future, besides hail suppression, it is desired to enact rain enhancement and uniformity of the rainfall. Based on the research conducted within U.C.C.G. Moldova 1 Iasi, there was noticed a lowering of the risk shown by the hailstone once the convective cells were seeded. Also, the clouds seeding with silver iodide (AgI) have increased rainfall within the protected areas, up 20 to 25% compared with the neighboring regions. In the future, for rain enhancement at the national level with aviation technology, importance, the results achieved following the experiments made in the southeastern part of Romania as a part of ‘The local experimental program at small scale for rain enhancement in the Banat Region, the western part of Oltenia, and northeastern part of Romania,’ during the years 2019 and 2021.
