Today, the sky in Beijing seems to be very different! Some citizens in Fengtai District photographed the sun halo, and “colorful auspicious clouds” floated over the East Fourth Ring Road again! How did such a beautiful scene come to be?
In this regard, the meteorological department said that the “colorful auspicious clouds” in everyone’s mouth is actually an arc around the horizon, also known as the sun-bearing or sun-bearing phenomenon, which is the most beautiful of all halo images, and its color order is from the top. The following are: red, orange, yellow, green, blue, indigo, blue-violet. The circumhorizon arc must appear when the sun is at least 58 degrees from the horizon, but at mid-latitudes the sun only reaches this altitude in June and early July, and only within a few hours before and after midday.
From this point of view, friends who are fortunate enough to see “Colorful Clouds” today are all lucky ones!
