It is said that there is a "Yun Qi" at the top of Mount Everest. What is this?

It is estimated that the top of Mount Everest will touch the clouds soon, and the visual experience must be great. Qiyun is a flag cloud formed by convective clouds. And according to the height and position of the flag cloud. Judge the magnitude of the wind force at the top of Mount Everest. That sounds amazing. It is estimated that many people's greatest wish in life is to climb Mount Everest. I believe it will bring new feelings.

Mount Qomolangma is the highest mountain on the earth, with an altitude of 8844.43 meters. It belongs to the Himalayas, located on the border between China and Nepal, and its peak is covered with snow all year round. The entire Everest Nature Reserve is divided into three types: core reserve, buffer zone and development zone. The terrain of the nature reserve is high in the north and low in the south, with complex and diverse landforms, with an average elevation of 4,200m, but its lowest point is only1.433m, with a relative elevation difference of more than 7,000m, forming a unique three-dimensional climate, which is characterized by "four seasons of snow on the top of the mountain, four seasons of spring at the foot of the mountain, four seasons in one mountain and different days in ten miles".

When the weather is clear, ivory clouds like flags often float on the top of Mount Everest, which is the flag cloud of Mount Everest. Yun Qi is formed by convective cumulus clouds, and the peak wind force can be inferred from its floating position and height. If the floating position of the flag cloud rises upward, it means that the wind power at high altitude is small, the wind direction is inclined downward and the wind power is strong; If it is flush with the summit, the wind is about nine. Therefore, Mount Everest Yun Qi is also called "the highest weather vane in the world".

Anyone who wants to climb Mount Everest will decide what to do according to the clouds. If the "Yun Qi" flutters from west to east, the cloud top is flat and smooth, the height of the cloud top gradually decreases after leaving the peak, or the cloud top fluctuates violently, it is not suitable for mountaineering activities above 7000 meters on that day; If "Yun Qi" flutters from southwest to northeast, the cloud top fluctuates greatly, and the height of the cloud top gradually rises after leaving the peak, which means that the wind speed in the upper air does not exceed 15 m/s, and mountaineering activities can be carried out above 7000 m on the same day.

Therefore, Yun Qi is really amazing. No wonder people will give it the title of the highest weather vane in the world.
