Humidity of Mount Everest

In summer (monsoon season), it is almost snow or rainfall every day. But at the summit of Everest, there are less chances of precipitation, except for the monsoon season.

Wind on Mount Everest

One of the most concerned issue that climbers worrying about is the high-speed wind which is frequently attacking. In dead winter from November to February, the global southwest-flowing jet stream moves in from the north, producing winds of hurricane force which beating the summit with a wind speed of over 285 km/h (177 mph). The winds strong and fast like this are extremely dangerous as they can blow climbers off the Mt. Everest easily. And winds over 160 km/h (100 mph) are its average level. There are suddenly strong winds even in the pre-or post monsoon season. The storms can blow the snow and ice down from the summit and cause problems for tourists and climbers.

During spring and winter, the westerly wind is blowing against the peak and around the Mount Everest summit. The moisture-laden air rising form Himalayas’ south slopes encounter with the wind and condenses in to a flag-shaped white cloud which sometimes portend storms. The speed of wind can reach about 80 km/h (about 50 mph), the flag-shaped cloud will be right at an angle to the summit. The air pressure at the summit is just about one-third of that at sea level. And the winds strong like this can result in lower air pressure and cause an additional oxygen reduction to climbers.
 
From June to September, Mount Everest is under the control of Indian monsoon. During this period, warm and wet wind from Indian Ocean blow to the south slop of Mount Everest which predict that frequent and violent snowstorms.
