The weather-modifying equipment used by Rain Enhancement Technologies in Utah Rain Enhancement Technologies States like Utah in the western US have been suffering from a record snow drought, raising fears of wildfires and low flow in the crucial Colorado river. But a start-up that releases negatively charged aerosols that can be carried up into clouds claims it has increased snowfall by 20 per cent in one Utah mountain range. Rain Enhancement Technologies compared snowfall in the La Sal mountains and the Abajo mountains 70 kilometres to the south during five recent dry winters. When the company was operating its high-voltage ionising array upwind of the La Sal mountains in January, the range received 9 centimetres more snow than would have been expected given the amount of snow the Abajo mountains got, the company says. But scientists caution that these results could have occurred by chance and it is too early to tell how well the technique works. “Cloud-seeding operations have been active for quite some time and we are offering another means of enhancing precipitation… …
