What experiments do humans have to control the weather?

1In August 1969, the United States and other countries conducted an experiment to suppress the storm "Debbie". Based on Barbados Island in the East Caribbean, it took three months to study the cloud type, temperature and wind speed with a special ship, 10 working boat, 24 planes, thousands of balloons and buoys, 7 artificial satellites, and 1500 people from 7 joint institutions, universities and independent research experiments in the United States and Canada.

Silver iodide was sprinkled twice around the eye wall of hurricane Debbie. Due to the catalysis, a new eye developed on the periphery of the original eye wall, and the old eye wall disappeared immediately, making the hurricane eye bigger, redistributing energy in the form of dispersion, reducing the maximum wind speed by 30% and reducing the disaster degree accordingly. This important achievement was achieved by mobilizing large-scale manpower and material resources, and it is the beginning of human control of the weather.
