The storm was the result of one of the UAE’s newest efforts to increase rainfall in a desert nation that gets about four inches a year on average. Washington, D.C., in contrast, has averaged nearly 45 inches of rain annually for the past decade. Scientists created rainstorms by launching drones, which then zapped clouds with electricity,the Independent reports. Jolting droplets in the clouds can cause them to clump together, researchers found. The larger raindrops that result then fall to the ground, instead of evaporating midair — which is often the fate of smaller droplets in the UAE, where temperatures are hot and the clouds are high. “What we are trying to do is to make the drop
