How low is the temperature at the top of Mount Everest? Do you know that?/You know what? Do you know that?/You know what?

Everyone knows that the highest mountain on earth is at the junction of China and Nepal, that is, Mount Everest. Many climbers go there every year, but because of the harsh environmental conditions there, many people go there and never come back.

What's the temperature at the highest point of Mount Everest? Due to extreme weather conditions, there is no weather station at the top of Mount Everest like other peaks. The nearest weather station to the top of the mountain is the heliostat weather station at the foot of Mount Everest. But as a climber, if you want to climb to the top of the mountain, you must know the surrounding temperature so that you can make adjustments at any time.

Under normal circumstances, the temperature will drop by 0.6 degrees for every elevation increase of 100 meters. According to this formula, the height of Mount Everest is 8848 meters, that is to say, the temperature at the summit is 53 degrees lower than the sea level at the same latitude. The climate of Mount Qomolangma is complex and changeable due to altitude and topography, and even in a day, it is often unpredictable, making it impossible to determine the weather at all.

From early June to September every year is the rainy season near Mount Everest. During this period, due to the influence of the southeast monsoon, extreme weather often occurs. But these months are the hottest. The average temperature at night is about 17 degrees, and it will be higher when the weather is good. 1 1 From mid-June to mid-February, the northwest cold current will affect this area. The lowest temperature can reach MINUS 50 degrees Celsius and the highest wind speed can reach 90 meters per second.

Up to now, the lowest temperature recorded at the top of Mount Everest is -6 1.3 degrees Celsius. It is speculated that the minimum temperature of Mount Everest may be as low as MINUS 65 degrees Celsius. The top of Mount Qomolangma is closer to the sun, but the temperature is much lower than that at the foot. What caused this? Actually, the answer is simple. As the altitude rises, the corresponding air will become thinner and thinner. At the top of Mount Everest, it is only one third of the atmospheric pressure at the foot of the mountain. Because thin air can bind less ground long-wave radiation. Therefore, the heat preservation becomes worse, and the natural temperature also decreases. Moreover, the top of Mount Everest is covered with snow all the year round, which leads to the enhancement of sunlight reflection. Therefore, the surface absorbs less heat, so the temperature is lower.
