Hail was and is one of the meteorological phenomena that affect agriculture, but also the entire economic activity of a region. Hail control methods and technologies began to be developed immediately after World War II.

The most effective way to combat hail is to seed the clouds. This method is also used by us in the fight against hail.

How does this method work? By different technologies (rockets, airplanes, ground generators) silver iodide, or other substances with the same effect are dispersed in the clouds when the hail is in the early stage of formation, and the silver iodide acts as condensation nucleus, preventing the formation of large hail, but keeping it at a much smaller size.

Drought is one of the biggest enemies of agriculture, and in recent years, with climate change, rainfall levels are declining, are unevenly distributed, and agriculture has significant annual losses, endangering the food security of the population.

Through techniques of active intervention in the atmosphere, dispersing materials such as liquid carbon dioxide, silver iodide, or salt, a noticeable change in the cloud formation process was observed, accelerating the speed with which it forms and increasing the concentration of water droplets. Thus, increases of up to 10% of the amount of forecasted precipitation are obtained.

Flood Control

The beauty of active interventions in the atmosphere on clouds is that using different substances we can get completely opposite results.

If silver iodide has the effect of increasing the amount of precipitation, the dispersion in the air of a certain amount of sodium chloride leads to a reduction in the formation of clouds and precipitation. Ideally, this material should be scattered above the clouds with the help of an aircraft, but there are other equally effective methods.

Floods cause both material and human damage, and often active interventions in the atmosphere have managed to reduce the tragic effects of these phenomena.

Cloud Seeding for Snow

A number of international studies have shown that active interventions in the atmosphere using silver iodide, used to control hail, can also have good effects and the amount of snow on the ground increases.
This type of material used in active interventions in the atmosphere is called glaciogenic material, and its efficiency is very good at negative temperatures.

For an efficient intervention, some atmospheric factors must be taken into account, such as the temperature, the presence of clouds on which the wind can intervene and the appearance of the wind.

From the studies carried out in various regions, the researchers concluded that the average time from the beginning of the interventions to the observation of the effects is about 30 minutes. Such interventions have led to snowfall even in areas where this phenomenon was very rare.
