Mount Everest is closer to the sun. Why is the temperature so low up there?

Mount Everest is closer to the sun, but the peak temperature is so low because the peak of Mount Everest is in the troposphere. The troposphere has an obvious feature. The higher it goes, the lower the temperature. Therefore, as long as Mount Everest is 1 km above sea level, the temperature will drop by about 6.5 degrees Celsius. In addition, the high altitude of Mount Everest makes the air above it very thin, and the thinner the air, the worse the heat insulation effect will be. Coupled with the high wind speed at the summit, the heat absorbed by Mount Everest is easily blown away, making Mount Everest very cold.

Some scientists have observed that at the same latitude, the temperature difference between Mount Everest at 8848 km and sea level is 53 degrees Celsius, and the temperature will continue to drop at 100 m above Mount Everest, which is about 0.6 degrees Celsius. What is the cause of this? The higher the altitude, the closer to the sun. The higher the temperature should be. But why is the temperature of Mount Everest so low? In fact, the most important thing is that Mount Everest is in the troposphere, and the height of 13 km is in the troposphere, so this height is the coldest.

We learned in junior high school geography that the earth's atmosphere is mainly divided into five parts. The troposphere is the closest place to the ground, and it is also the densest part of the five layers of the atmosphere. The most obvious feature of this layer is strong convection, so it is named troposphere. In the troposphere, all the bad weather we usually encounter occurs in this layer. In addition, the troposphere has a characteristic, the higher the temperature, the lower the temperature, which also leads to the colder the temperature of Mount Everest.

In geography class, we also know that the heat on the earth mainly comes from the surface of the earth, and the heat on the surface of the earth comes from absorbing the heat from the sun. However, the altitude of Mount Everest is too high, and the biggest feature of high altitude is strong wind. Almost all the heat absorbed by the surface from the sun was blown away by the wind, which made it impossible for Mount Everest to store heat, which also led to the low temperature of Mount Everest.
