Will the catalysts used in artificial weather modification operations cause pollution?
Catalysts used in weather modification operations, such as dry ice, liquid nitrogen and silver iodide, have chemical properties in the atmosphere that prevent them from causing environmental pollution.
1. Dry ice and liquid nitrogen: These two substances form carbon dioxide and nitrogen respectively after vaporization. They are all part of the air and do not have harmful effects on the environment. Therefore, they are considered "ecological security catalysts".
2. Silver iodide: Internationally, silver iodide is mainly used for artificial rain enhancement operations, and its work efficiency is high. Long-term monitoring found that the amount of silver iodide used in aircraft silhouette operations and rocket silhouette operations is very small, and the concentration of silver ions accumulated in water and soil in the operation area is far lower than the concentration specified by the World Health Organization.
Judging from current scientific research and practical applications, these catalysts used in artificial weather modification operations will not cause pollution to the environment. However, with the advancement of science and technology and the improvement of environmental requirements, continued in-depth research and monitoring will be needed in the future to ensure its safety.
Artificial weather modification operations
Artificial weather modification operations refer to the physical and chemical changes in the local atmosphere through scientific and technological means under appropriate conditions in order to avoid and mitigate meteorological disasters, rationally utilize climate resources, Manual intervention is required in the process. This kind of operation aims to achieve the purpose of increasing rain (snow), preventing hail, eliminating rain, eliminating fog, and preventing frost.
my country’s operational capabilities and management levels in this area have been continuously improved. This business has become an important support for agricultural production and has also played an important role in disaster prevention, reduction and relief, ecological civilization construction, and protection of major events. .
The regulations stipulate that artificial weather modification work needs to be organized, implemented, guided and managed by meteorological authorities according to the scale of the operation and the scope of influence, under the leadership and coordination of the local people's government at or above the county level in the place of operation. To carry out artificial weather modification work, a weather modification work plan shall be formulated, and local disaster prevention and reduction needs and operational effects shall be fully considered.
The China Meteorological Administration has drawn up a blueprint for the development of artificial weather modification work in the next five years and clarified its long-term goals until 2035. It provides an action plan for artificial weather modification during the "14th Five-Year Plan" period.
