At this time of year in the UAE, it is blisteringly hot, with temperatures regularly reaching 50C. On average, the country gets just four inches of rainfall every year. However, Dubai faced torrential rainfall this week due to the complex procedure of cloud seeding. Cloud seeding involves firing either electrical charges or chemicals (such as silver iodide) into the clouds. Water droplets merge and stick together when they receive an electrical pulse, and once the droplets are big enough, they will fall as rain. There are clear dangers of controlling the weather - for example, while cloud seeding increases precipitation, it's hard to control the rate at which rain falls, which could lead to flooding. We also don't know the effects of the chemically induced method of cloud seeding, such as the impact of these chemicals on agriculture. The Emirates are expected to get drier, and so that makes finding water resources from anywhere, including electrified clouds, a priority. Cloud seeding could help recharge aquifers and take some of the strain off desalination plants, however water conservation also needs to be ramped up in a lavish city like Dubai.
