China inducing rainfall to combat severe drought

China has developed a system of artificial rain, which helps to cope with the effects of abnormal heat in cities.
High-rise buildings are equipped with special water "guns" that spray powerful jets of water.
According to a study by Peking University, China's meteorological services have successfully tracked the weather in 2021 and actively used cloud seeding technology. This is a weather modification method in which chemicals such as tiny particles of silver iodide are added to clouds, causing water droplets to collect around them and increasing the chance of precipitation.
According to the researchers, cloud seeding in anticipation of major holidays leads to a noticeable reduction in air pollution. For example, ahead of the 100th anniversary of the Chinese Communist Party, artificial rain reduced PM2.5 air pollutants by more than two-thirds and changed the quality index based on World Health Organization standards from moderate to moderately good.
Last year, Beijing announced plans to expand its weather modification pilot program to an area 1.5 times the size of India, 5.5 million square kilometers. The State Council of the People's Republic of China announced that it intends to develop a weather modification system by 2025, in particular with anti-hail technology.
