The reason for that abnormal blood-red sky in Zhoushan was found.

There was a blood-red sky anomaly in Zhoushan, and the staff of the local meteorological bureau responded that the refraction and scattering of this light, due to the good meteorological conditions that day, more water in the atmosphere formed aerosol, and the light source or ship lights in the port refracted and scattered, so the sky was dyed red.

Meteorologists also mentioned that it is common for the sea and sky to turn red, but this time it was particularly red.

According to the investigation of Zhoushan Radio and Television, the incident happened at the dock of Zhouyu Company. At that time, an ocean-going ship was parked on the dock, and the red light was the lamp of saury. Red and yellow are the two longest wavelengths of visible light, and they have strong penetrating power. In addition, there is a lot of suspended water vapor in the air, so this "strange phenomenon" has appeared.

In fact, it is normal for the sky to change color, which has happened many times in history. 1770, blood shed appeared in many countries for 9 days, and a similar situation occurred in Northeast China.
