3D SA company is one of the most innovative companies in the world in weather management, as well as in everything that has to do with preventing-facing extreme weather phenomena. It is a member of the Weather Modification Association and udertakes such programs since 1981.

The management of weather conditions is performed by using specially modified aircrafts, weather radars and qualified staff. The company’s goals are to increase rain and snowfalls (in order to face the drought and to store up water), to protect from hail (so that the damage caused both to crops and to people’s fortunes are restrained), to displace the cloud’s water mass (to avoid floods).

Such programs for weather management and protection from extreme weather phenomena can be performed during the whole year. Hail protection is usually performed during the warm months because this is when the stormy clouds most develop, but on the other hand, projects for the increase of rain have better results during the cold months.

The method used for the performance of such programs is based on the penetration of condensation cells in the atmosphere, wherever there is enough humidity. However, because of their absence, either it’s impossible that water drops or ice cells are formed or due to the small number of cells, big embryos are created which fall to the ground as hail.

When 3D SA carries out such programs, it uses the direct penetration method, which means the seeding of Silver Iodide (AgI) or dry ice from aircrafts to the target area at the right moment, in order to have the best results possible. This is how the available humidity of the atmosphere is divided into more cells – ice crystals, which finally fall on the ground as rain or snow.

Various researches in the past have shown that the environment is not affected by the clouds seeding. As for the animals, plants or the ground, in areas where the projects of weather modification were carried out, the quantities of AgI have not exceeded those already existing in the environment.

Weather management programs cannot reduce the drought expected for summer nor create clouds if there is no humidity in the atmosphere. It is possible, though, when the conditions are favorable to seed, to increase the water stored from rain or snow during winter, so that it is properly managed during the dry months.

Similar projects are carried out all over the world. The digital weather radars’ capacities help to observe clouds better and give quantitative and qualitative weather data in real time. Due to the fact that we must:

• Foresee in time and precisely the importance of the weather problem and take the proper measures to face it.

• Protect some specific predetermined rural or urban areas from hail.

• Increase the available quantities of water to develop some basic fields of the economy, such as energy, tourism, agriculture, which wane constantly.

• Have sufficient quantities of water for the present, but even more for the future for urban use.

As a result, we have to manage in a better way the atmospheric water in order to:

• Cause rain or snow in areas that we have already chosen (catchment basin, lake, forest, mountain, specific areas of storage etc) so that problems of scarcity and desertification

• Cause rain in some areas, reduce or increase its volume and avoid any problems of precipitation in other more crucial ones (as to avoid an inundation or an overflow

• Protect crops from hail by transforming it into rain

• Create and store water when possible and consume manage it later (for example in periods of drought)
