Mars with the same paragraph! Appear over Beijing? Blue sun? How amazing is it?

1. What happened over Beijing? Blue sun? What is it like? Friends living in Beijing believe that the blue sun in the sky is still vivid. It sounds like an unusual existence, but it really appears in the sky of Beijing. On the day of the incident, there was dusty weather in Beijing. The whole sky was foggy and the visibility was very low, but at this time, someone found that the sun in the sky turned blue. When we stand on Mars, it looks like the sun. Everyone feels incredible about this sight, because the sun we know is basically yellow or red, and it is rare to have such a strange blue color, which also opens our eyes.

Second, what is the reason for this phenomenon? In fact, the blue sun seems incredible to all of us, but it is a very natural phenomenon for researchers. The appearance of this blue sun was actually due to the dusty weather in Beijing that day. The dust particles in the dust react physically in the air, which is what we all call Michaelis scattering. The final result of this Mie scattering is the blue sun we see, which is actually an optical reaction and can be completely explained by science.

Third, how to evaluate the emergence of this phenomenon? People who understand the principle of this blue sun phenomenon should be very clear in their hearts that it is because of er caused by dusty weather. The reason why there will be dust weather is that the vegetation coverage on the surface is reduced, which leads to dust being carried into the sky when it is windy, thus forming dust weather. The impact of dusty weather on people's lives is actually very great. On the one hand, reduced visibility may lead to a series of accidents. On the other hand, it is also a great threat to the human respiratory system, so it also reminds us that we must protect our environment, care for our nature, reduce the harm caused by all human activities, and make dusty weather disappear in our lives.
