Recently, a photographer took photos of his friend in a sea of flowers and happened to have a Dingal effect. As soon as the short video was released, it immediately sparked heated discussion on the Internet. So what is the Dingal effect and how can we observe the Dingal effect? Let's hear what the meteorological experts say.
In the video footage, a woman in pink ancient costume slowly walked in the sea of flowers. Suddenly, a beam of light "scattered" in the sky, shining on the woman, as if she was in a "spotlight", dancing with the woman. The picture was mysterious and beautiful.
video shooter: "A drone took a photo. When the photo was almost out of power, it landed at this position on the level of the flower plane and the sea of flowers, and then turned around and saw this beam of light." As soon as the
video was released, it immediately aroused heated discussion among netizens. Everyone wanted to know how this "concentration" was formed? In this regard, Guo Rongfen, chief service of Yunnan Meteorological Bureau, said that this is actually the Dingdar effect, an optical phenomenon.
Service Chief Guo Rongfen: "The Dingdar effect is simply when the sunlight passes through the gaps of the clouds, and the bright paths appearing in the clouds can be observed from the vertical direction of the incident light. It is a kind of radiant effect that we see. It has many beautiful alias, such as Angel Ladder, Dawn and Twilight , etc. To put it bluntly, it is the light in the gaps of the clouds, just the light in the gaps of the clouds."
When the Dingdar phenomenon appears, the light has a shape. They are sometimes cylindrical and sometimes conical. The scene is spectacular and deeply loved by photography enthusiasts. So what everyone cares most about is: Under what circumstances can this phenomenon be observed? Guo Rongfen said that for observers on the ground, as long as clouds or fog block the sun, it is possible to see such a phenomenon.
Yunnan Provincial Meteorological Bureau Chief Service Office Guo Rongfen: "The most important thing is that there must be particulate matter such as water vapor and dust in the air. Therefore, the Dingdal phenomenon is cloud gap light. It is more common in cloudy weather. On clear days, it often occurs at sunset. The better observation locations are generally in wide rivers, lakes, seas or valleys with heavy humidity. Occasionally, the cloud gap and cloud gap light will appear together with anti-cloud gap light. The cloud gap light, that is, the Dingdal phenomenon is mostly red or yellow."
meteorological experts introduced that the Dingdal effect is actually in me. They also play a huge role in their lives. For example, when bad weather such as haze, sandstorm, and other bad weather, the visibility of traffic roads is low. In order to avoid misjudgment of traffic signals, people use the Dingdal effect to design a new type of traffic light auxiliary device. When the red light is on, the intersection signal light will emit multiple beams, forming a visual impact to help drivers accurately determine traffic signals. In addition, the spotlights in the dark, flashlights in the dark environment, night laser lights, etc. are the specific applications of the Dingdal effect in life.
