Extreme Weather: The Weather of the Summit of Mt. Everest

On May 11th, Nepali climber Apa Sherpa (a resident of Salt Lake City, Utah) made his 21st successful ascent of Mt. Everest, breaking his own record for the most such by any mountaineer. There is a small window of time used by most climbers for the ascent of the world’s tallest mountain (for now with an official elevation of 29,028’/8848 meters—but measured at 29,035’/8850 meters by the National Geographic Society in 1999). That window of opportunity is the month of May when the jet stream normally shifts to the north of the Himalayan Range and relaxes its icy blast on the summit. In fact, all but three of Apa’s successful climbs of the mountain were accomplished during May.
