UAE meteorological officials said their cloud seeding efforts can increase rainfall by anywhere from 10% to 30%. Meanwhile, in the U.S., meteorological authorities in California say rainfall can increase by 5% to 10%, while in Nevada, the Desert Research Institute says precipitation can increase by about 10%, according to Time. While the UAE was running cloud seeding missions this week, the NCM told CNBC it hadn’t seeded any clouds on Tuesday before the storm hit. The denial comes after Bloomberg reported that specialist meteorologist Ahmed Habib said the Tuesday rains stemmed partly from cloud seeding.
