The drones “shocked” the clouds with electric shocks

Charging on clouds works by causing water vapor to collect in larger droplets, which when combined, fall to the ground in the form of rain

High temperatures and high heat in the United Arab Emirates are nothing new, but that is why the latest way for the city to cool down in such weather conditions is the top range of modern technology.

At air temperatures that often approach values ​​of 50 degrees Celsius, scientists began experimenting with the technology of “cloud illumination”, which brought results for the first time last week.

Heavy rains that soaked the streets of Dubai and cooled the city were caused by drones that emit electrical impulses. Unlike the previously known method of causing precipitation by spraying silver iodide into clouds, the new technology is, conditionally speaking, based on the production of “electroshocks”. Charging on clouds works by causing water vapor to collect in larger droplets. When smaller droplets merge into larger ones, they fall to the ground in the form of rain.

Drones that “sow rain” have a wingspan of two meters and are launched from a catapult. They have temperature, humidity and electricity sensors, as well as a special system for generating electrical impulses. The autopilot can maintain drones while cruising through the clouds for about 40 minutes.

The technology was devised by British scientists from the University of Reading back in 2017, while the Emirates began testing it in March this year. Although there were some doubts, this method proved to be realistically applicable.

Testing has successfully shown that “electroshocks” can create large enough droplets that can trigger precipitation that will be able to “survive” until they reach the ground. The UAE National Center for Meteorology has invested 1.5 million dollars in the realization of this project.
