What are the climatic conditions of Mount Everest?

Mount Qomolangma is mountainous and has a unique geographical environment. The lowest temperature all the year round is MINUS 30-40 degrees Celsius.

It doesn't snow all the year round in some places on the mountain, and glaciers, ice slopes and ice towers can be seen everywhere. The air at the summit is thin, and the oxygen content in the air is only a quarter of that in the eastern plain, and there are often seven or eight strong winds. Generally speaking, the rainy season is from early June to mid-September every year, and the strong southeast monsoon leads to frequent rainstorms, fog, ice and snow, and unpredictable. 165438+1From mid-October to mid-February of the following year, due to the strong cold current in the northwest, the lowest temperature can reach -50℃ and the average temperature is around -30℃. The maximum wind speed can reach 90 meters per second. Every year from the beginning of March to the end of May is the spring from windy season to rainy season, and from the beginning of September to the end of 10 is the autumn from rainy season to windy season. There may be better weather during this period, which is the best season for mountaineering.

Because of the extremely cold climate, it is also called the roof of the world. According to the radiosonde data of heliostat weather station at the foot of Mount Everest, it is the coldest in February with an average temperature of -27. 1℃, and the hottest in August with an average temperature of-10.4℃ and an annual average temperature of-19.6℃. The average temperature of -30℃, plus the average wind speed of tens of meters per second, plus the sudden bad humidity. If you are interested, you can convert the somatosensory temperature according to the formula, and this is only the average data. In the extreme rainy and windy season, I'm afraid this value will increase a lot. How exaggerated is this temperature? In the climbing history of Mount Qomolangma, since 1953, only 0.2% of the successful climbs occurred in winter, and 0. 1% occurred in summer. It can be said that at least so far, the progress of science and technology and the accumulation of experience can't cope with this temperature.
