Rare!!! What is the cause of the red sky anomaly in Zhoushan?At the same time, weibo users
"back in Shanghai SH" analysis said it was only a weather phenomenon,can use "Rayleigh scattering"
explanation, "zhoushan last night in a nearby clouds gathered a large number of tiny particles, the
diameter is about 0.7 micron particles accounted for the vast majority of its diameter similar to red
wavelengths of the sun, after scattering the sky red." "According to local authorities in Zhoushan,
there was a fishing boat near the harbor at that time, which happened to have a red light, aggravating
the Rayleigh scattering effect," the netizen added.
An expert from the Space physics research team of China University of Geosciences (Wuhan) said that solar and
geomagnetic activity on May 7 was calm and there were no significant anomalies in solar activity, which basically
ruled out the possibility that geomagnetic and solar activity caused the sky to be red. "The weather conditions in
Zhoushan that day were cloudy to rainy, with fog and high humidity in the lower atmosphere. There was a yellow
alert for fog. Because the light of ocean-going fishing boats is red, the red light has a long wavelength and strong
penetration. Meanwhile, the scattering of liquid droplets in the atmosphere will scatter the red light over a long range,
and thus present an abnormal red light phenomenon in a sky area."
"Yesterday (May 7) night fog was not as big as the previous two days, visibility from the video is still ok, but last night
there were more clouds, coupled with the sky drizzle, may be a refraction of light from the low cloud system.
" Zhoushan meteorological Bureau staff said that the red sky is a refraction and scattering phenomenon of light, when
the weather conditions are better, more water in the atmosphere to form aerosols, light source or port ship lights.
