The staff of the local meteorological bureau responded that this kind of refraction and scattering of light belongs to the refraction and scattering of light. Due to the good weather conditions that day, there is more moisture in the atmosphere to form aerosols.Light source or light for ships in the portafter refraction and scattering, so the sky is dyed red.
In addition, meteorological experts also mentioned that it is relatively common for the seaside sky to turn red, but this time it was especially red.

The two colors of red and yellow have the longest wavelengths of visible light. They have strong penetrating power, and there is a lot of suspended water vapor in the air. This “weird phenomenon” occurs .
In fact, the discoloration of the sky is a normal situation, and it has happened many times in history. In 1770, there was a blood-colored sky that lasted for 9 days in many countries, and a similar situation occurred in Northeast my country.
In 2017, Japanese scientists published a paper in the “Astrophysical Letters”, arguing that the 1770 bloody sky event was caused by super-large solar activity.
However, the sky change in Zhoushan yesterday (May 7) has nothing to do with solar activity, it is purely a coincidence.”Inactive man-made natural phenomenon”, which also indirectly explains why the red color in the sky disappeared in a short time.
