On May 7, a strange red color appeared in the sky of Zhoushan, Zhejiang Province, which immediately aroused heated discussion and rushed to the hot search list. The staff of the local meteorological bureau responded that this belongs to the refraction and scattering of light. Due to the good meteorological conditions on that day, there is more water in the atmosphere to form aerosols, light source or ship light in the port , after refraction and scattering, it dyed the sky red.
In addition, meteorological experts also mentioned that it is common for the sea to turn red, but this time it is particularly red.
However, what the light source is remains a mystery. On the afternoon of May 8, @ elephant news released a news that the reason for the abnormal sky has been found, and it is a fishing boat.
According to the Zhoushan radio and television survey, the location of the incident happened to be the wharf of the boat fishing company. At the wharf, there was an ocean going ship fishing for Northern Pacific saury. The red light was the light of the saury ship. The light wavelengths of red and yellow were the longest in the visible light, with strong penetration. Coupled with the large amount of suspended water vapor in the air, this "strange phenomenon" appeared.
In fact, sky discoloration is a normal situation and has occurred many times in history. In 1770, there was a bloody sky for nine days in many countries, and a similar situation also occurred in Northeast China.
In 2017, a Japanese scientist published a paper in Astrophysics express, believing that the bloody sky event in 1770 was caused by large-scale solar activity.
However, the sky change in Zhoushan yesterday (May 7) has nothing to do with solar activity. It is purely a " non active man-made natural phenomenon " under various coincidences, which indirectly explains why the red in the sky disappeared soon.
