The rocket is outdated, and now it is popular to use drones to engage in artificial rainfall.

Speaking of drones , I am afraid most people think of aerial photography, but this guy's ability can not only do this. Recently, researchers and operators in Nevada successfully conducted a test flight, and they wanted to bring precipitation to the drought-affected areas through drones. The test flight in Hawthorne was approved by the Federal Aviation Administration (FAA), using a drone called Sandoval Silver State Seeder, which reached 11 feet (about 3.35 meters) during flight. The silver iodide carried can be sprinkled in the air.

The plane climbed to a height of 400 feet (approximately 121 meters) during the test flight, but ultimately failed to bring any precipitation. However, from a technical point of view, “The trial was a great success and was significant for both Nevada and project participants.”

Amber Broch, chief engineer of the project, said: "This test tells us that drones have great potential in environmental science and natural resource utilization."

In fact, people have long had mature artificial rainfall technology. Previously, in order to ensure the smooth opening of the opening ceremony of the Beijing Olympic Games, meteorologists also used rockets to sprinkle silver iodide into the air in advance to take the initiative to "seek rain." However, compared with the rocket, the drone is more controllable and the effect of controlling the rain will be better.
