What is the reason for the abnormal blood-red sky in Zhoushan?

The abnormal blood-red sky in Zhoushan may be caused by fishing lamp+suitable weather+camera filter.

Speaking of Zhoushan, I have to mention Putuo Mountain. My impression of Mount Putuo is that there are many temples, many letters and many dried fish. The tourist shops around the scenic spots are all aquatic products, so we know that Zhoushan, Zhejiang Province is a city rich in aquatic products. Since ancient times, there have been thousands of fishermen in Zhoushan and fishing boats can be seen everywhere.

With the development of fishing technology, our modern fishing boats will use lights when fishing, and red lures will be used when fishing saury. When the fishing of saury is over, the red lure light will be turned on. If it is a large fishing boat, dozens of red lure lights will be turned on together, and the sky will be illuminated by red light.

When the weather is clear, the red lure lights of fishing boats can only dye a small piece of the sky red. At this time, we can also see that this is the light of a fishing boat. When there is dense fog in the air, the red light will be scattered by the fog and dyed into a large red sky. What a coincidence! It was foggy that day.

Most of us see this phenomenon through photos taken by local people. Our first impression is that the sky is like blood. It looks spectacular and strange. However, according to my own experience that shooting night scenes is always a mess, it is a bit difficult to shoot such full and magnificent colors without some technical means.

This red sky is not the first time. On September 9, 2020, after entering the high temperature and dry season, many places in the United States were swept by mountain fires. Oregon, USA, produces a lot of smoke because of the continuous mountain fires, and countless small particles float in the air. At this time, the whole sky was blood red due to Rayleigh scattering, and local residents even lamented on social media: "This is the end of the world" and "It's like living on Mars" ...

In addition to red, this sky scene has many forms:

On the night of May 6th, 20021year, dozens of shining pillars appeared in the night sky of Fukui Prefecture, Japan. These light beams are hung above people's heads with the naked eye. Just as people are busy calling friends to look up at the sky, this wave of light has begun an all-night parade. They first swaggered over Fukui City until 1 1: 30 at night. Just when people think they should fade out, right? As a result, in the morning 1, they appeared in the night sky of Hyogo Prefecture.

In 2020, a big fireball crossed the night sky in Australia, and then the surrounding area turned blue-green. At first, scientists analyzed that space junk may have fallen, but it seems that the mysterious blue fireball has always been "favored" by Australia. It has been visited many times in recent years, and scientists have been conducting in-depth research. I hope scientists can get the research results as soon as possible.

On 20 18, the night sky turned blue in new york, USA. It looks as if a Star Wars is about to be staged, but it is actually a transformer explosion caused by a fire.

The colorful sky in Chengjiang in 2020 is caused by the refraction of light when the high-speed light belt meets fog.

With the development of science and technology and the frequent occurrence of extreme weather, this rare astronomical phenomenon will become more and more common.
