When the weather is clear, why do flag-like milky white clouds often float on the top of Mount Everest?

When the weather is clear, ivory clouds like flags often float on the top of Mount Everest, which is the famous Mount Everest flag cloud. Yun Qi is formed by convective cumulus clouds. According to its floating height and position, it can also be used to infer the wind force at the top of Mount Everest.

We have learned in high school geography that convection requires heat source, and the heat source of Yun Qi convection at the top of Mount Everest comes from ground radiation. Moreover, the higher the temperature, the stronger the ground radiation and the more obvious the air convection movement. This explains why milky white clouds like flags float on the top wall of Mount Everest when the weather is clear.

Bian Xiao also found the Yun Qi of Mount Everest and the title of "the highest weather vane in the world" by searching for information. People can predict the weather according to the change of weather direction. As we all know, Mount Qomolangma is the highest mountain in the world, with an altitude of more than 8,400 meters, so it is obviously influenced by the high-altitude westerly wind. When the flag cloud rises, it shows that the convection movement is strong and the wind at high altitude is small. At this time, the surface temperature is high, which is beneficial to mountaineering. When the flag cloud floats horizontally, it shows that the convection movement is weak and the wind is strong, which is not conducive to mountaineering. With this function, people can choose the right time to climb the mountain.

Knowledge is the best weapon to arm yourself. With a good knowledge reserve, it can effectively help us solve all aspects of life. Therefore, at any time, we must persist in learning, persist in lifelong learning, and constantly absorb new knowledge to replenish our new "blood", which can also be used to improve ourselves and become a better self.
