The reason for the blood-red sky anomaly in Zhoushan may be the fishing lights + proper weather + camera filters.
When it comes to Zhoushan we have to mention Putuoshan, my impression of Putuoshan is that there are many temples, many beliefs, many dried fish, attractions around the tourist stores, aquatic products that are a wide range of dazzling, so we know that Zhoushan, Zhejiang Province, is a city very rich in aquatic products, since ancient times, Zhoushan, there are thousands of fishermen, fishing boats can be seen everywhere.
With the development of fishing technology, our modern fishing boats will use lights when fishing, catching the fall swordfish use a red-colored bait light, when fishing the fall swordfish closing stage, will turn on the red-colored bait light, if it is a large fishing boat, dozens of red-colored bait light when turned on together, there will be a piece of the sky is lit up by red light.
In the case of relatively clear weather, the fishing boat red-colored light can only dye a small piece of sky, this time we can also tell that this is a fishing boat lights, when there is a dense fog in the air, the red-colored light will be scattered around by the fog, dyeing a large area of the sky, it is so coincidental, that is the day there is a big fog.
Most of us saw the phenomenon through photos taken by locals, and our first impression of the sky was as if it was sprinkled with blood, looking spectacular and eerie. But I know from my own experience with night photography, which is always a mess, that it's a little hard to get such full, magnificent colors without a little technical skill.
This red sky is not the first time. 2020 September 9, into the hot dry season after the United States, many places suffered a mountain fire swept across the United States, the United States, Oregon, because of the continuing fires produced a large amount of smoke, countless small particles floating in the air, this time the sun because of the Rayleigh scattering, the whole piece of the sky is a blood-red color, the local residents are in the social media to exclaim: "It's like the end of the world", "It's like living on Mars" ......
In addition to the red color, there are many other forms of this visionary sky:
2021 On the night of May 6, 2021, dozens of pillars of glowing light appeared in the night sky in Fukui Prefecture, Japan. These pillars of light hung above people's heads to the naked eye, and just when people were still busy calling out to their friends to look up at the sky, the wave of light pillars had already started an all-night parade. They first swaggered across the Fukui City sky until 11:30 PM. Just when people thought it was time for them to subside, right? It turned out that at 1 a.m., they appeared in the night sky of Hyogo Prefecture.
In 2020, a large fireball streaked across the night sky in Australia, then lit up the surrounding area in a blue-green color. At first, scientists analyzed that it might be space junk falling down, but it seems that the mysterious blue fireball has always been very "favorable" to Australia, and has been visited many times in recent years, and scientists have been studying it in depth, hoping that scientists can come up with the results of the study soon.
In 2018, the night sky in New York City turned blue, and it looked like there was a star war going on in the sky, but in fact it was a transformer explosion caused by a fire.
The colorful sky that appeared in Chengjiang in 2020 was produced by the refraction of light when a light strip on Cheng Cheng Expressway met fog.
With the development of technology and the frequency of extreme weather, such rare sky phenomena will become more and more common.
