Weather forecast in Yun Qi.

Under normal circumstances, there is a strong westerly wind blowing over the plateau, and the direction of the flag cloud will point to the east; If the flag cloud points to the north, it means that it will snow soon; The flag clouds rising like smoke also indicate that the weather will get worse.

The flag cloud of Mount Everest is of course caused by its special landform. Scientists have found that the surface of Mount Everest below the plateau at an altitude of 7000 meters is covered with ice and snow. From more than 7000 meters to the top of the mountain, there are gravel slopes. After the sun came out, the gravel slope was heated quickly, and the hot air rose along the slope and began to condense into clouds near the height of the summit. When the cloud is higher than the peak, it is immediately blown to the east by the strong west wind, so a "cloud flag" flies high at the peak.
