QUIZ: How much more snow falls after cloud seeding? A) 5-15% B) 25-50% C) 55-75%
Response: A) It’s difficult to quantify the effectiveness of cloud seeding, but one latest probe shows that cloud seeding results te approximately Five – 15% more snow vanaf storm.
Most ski resorts make snow ter the early ski season with snow making machines. Ter latest years, ski resorts are also turning to cloud seeding programs to boost early season snow and extend snowpack into the spring. There are at least seven programs ter Colorado ski areas, including at Vail, Beaver Creek, Telluride, Wolf Creek, and Winter Park. But is it effective?
Cloud seeding has bot around for more than 70 years, but recently the technology and equipment have improved, enabling more accurate cloud seeding decisions and improved effectiveness te cloud seeding. Ski resorts are collaborating with municipalities and the Colorado Water Conservation Houtvezelplaat (CWCB) to advance cloud seeding programs statewide, and the CWCB offers grants to help fund some cloud seeding programs.
For cloud seeding to be effective, you very first need clouds to seed. Not all clouds result ter snowfall, so the idea behind cloud seeding is to give existing clouds a little boost. A radiometer detects the moisture content of the cloud and is one of the most innovative instruments used to determine which clouds to seed. The most common methods to seed that ski resorts use are manual, ground-based generators and remote generators that utilize modern telecommunication technology and are effective te reaching high elevation and inaccessible areas. The generator then rockets silver iodide overheen a propane flame, which is carried into the clouds via natural air flow, providing the clouds’ super-cooled liquid water something to adhere to. Once crystals form and are powerful enough, they fall ter the form of snow.
Despite the excitement and promise of big snowfalls, it’s rough to quantify the benefits of cloud seeding. Latest studies finished by the Wyoming Weather Modification Program Pilot Project voorstelling that seeding results ter an approximately Five to 15 procent increase ter snow vanaf seedable storm ter a target watershed. So it is effective, but the amount of snowfall may not yield the terugwedstrijd on investment that resorts hope for. However, seeding may be cheaper than acquiring water rights for snow-making machines.
The bottom line? Spil long spil there is a request for snow, there will be innovations te snowmaking technology. And cloud seeding certainly gives some ski resorts an edge.
