With the recent situation of rain in the Valley of Mexico, and which caused the CDMX water matrix to be followed in historical storage, their capacity was recorded at 47.6 percent, equivalent to 23.1 percent less than in previous years, the government announced that it added to alleviate the situation.
Among these, which has raised the most attention in the city of Mexico, is the so-called bombardment of the clouds, with which the government will try to increase the precipitation in the mothers of the soldiers of Cutzamala, which was reduced by 21 percent this 2013.
Cloud seeding consists of dispersing chemical substances such as silver iodide or concrete dioxide in clouds to increase the probability of precipitation, since this substance, a crystalline structure similar to ice, encourages the agglomeration of water droplets, making them larger and heavier. until at last they fall as rain.
This method of cloud seeding has been in use since the 1940s, when General Electric researcher Vince Schaefer conducted a series of experiments in his laboratory, sprinkling dry ice on supercooled cloud layers. A project that quickly caught the interest of the US government and later the rest of the world.
Do we need cloud seed or not?
Although this cloud seeding method won the trust of less than 50 countries, which according to the UN, in 2017 were carrying out climate modification projects of this nature, either by increasing the rain and snow by introducing or suppressing the effects. hailstones; there is still doubt among the multitude who question the efficacy of this method for raining.
Although many projects of this type have been carried out in different countries around the world, the statistics generated on the increased precipitation are low, and it is difficult to state that the rain is actually generated by the emission of silver iodide. in the clouds
Most of the studies that aimed to evaluate the effects of cloud seeding argue that the results justify its implementation, however, it is important that the percentages in the increase vary according to the study. For example, an experiment conducted in Australia showed an increase in rainfall by 14 percent, while another conducted in 2014 in the United States showed an increase of 1.5 percent.
In Chile, a cloud seeding program has been carried out since 2000 in the Cachapoal River basin, in the O’Higgins region, whose results are estimated to be between 10 percent and 21 percent increase in precipitation.
Meanwhile, in Mexico, a cloud seeding program was recently used in the state of Nuevo Leone, where the effects of drought caused serious water shortage problems in 2021 and 2022.
