Dubai says freak rain was caused by cloud-seeding drones

The video discusses the unusual rainfall in the UAE, attributed to cloud seeding efforts. The UAE uses drones that induce electricity to seed clouds, developed in collaboration with the University of Reading. This technology aims to increase precipitation in the arid region, which typically receives only 10 centimeters of rain annually. The electrical charge from the drones helps water droplets clump together, forming larger clouds capable of producing rain. This method is crucial for enhancing rainfall in the desert climate of the UAE.

Explain the process by which electrical charges help in cloud formation.

Why is precipitation important for the UAE, and how much rain does it typically receive?
