A National Geographic expedition in May installed the highest weather station in the world. It’s on Mt. Everest about 1,500 feet below the summit. It’s one of only a handful of places on the planet that reaches into the little understood sub-tropical jet stream. Researchers hope the data they gather on the jet stream will help them better understand how the highest elevations of the planet are being effected by climate change. Baker Perry is an Appalachian State geography professor who was on the team that installed the weather station.
