The same Mars "blue sun" reappeared over Beijing. What does this sun look like?

The sun in Beijing once again attracted everyone's attention. On March 28th, Beijing ushered in dusty weather. Under such circumstances, it is very strange for careful people to find that the sun in the sky has changed color, not the previous color, but the blue sun. They took photos and posted them online. As you can see from the photo, the shape of the sun is very clear. Under the influence of dust, people can see the sun more clearly than before, and there is nothing.

The reason why the sun turns blue is mainly influenced by dust in the air. The particles in the dust scatter and absorb the red light with longer wavelength, which leads to the reduction of red light, so it appears blue. The sun of this color is the same as the sun on Mars. From this aspect, we can also see that the weather in Beijing was rather bad that day. There is more dust in the air, which has a great influence on daily travel and is not conducive to everyone's travel. It is precisely because of the serious sandstorm that day that everyone must make serious preparations and take corresponding protective measures before going out to ensure that they will not be affected by sandstorms when traveling. This kind of weather is also very common for Beijingers. After all, Beijing has experienced a lot of such weather. Although the environmental improvement in recent years is very obvious, some problems have not been completely cured, so you can see such a strange sun scenery in Beijing.

Sandstorms are very harmful, especially to the local environment. As soon as the sandstorm comes, the air is full of particles. Under the baptism of sandstorm, the cars parked outside were covered with a thick layer of sand, and the roads, roofs, streets and trees were all yellow. After the sandstorm, it is very difficult to clean up, and it often takes a long time to clean up, which is also a big expense for the cleaning cost. There are many factors that cause sandstorms, mainly man-made excessive damage to the environment, which leads to the birth of this weather. Therefore, everyone should respect, love and protect nature, and remedy what has been destroyed as soon as possible to minimize the damage to nature. Although this can not be fully recovered, it can alleviate some environmental pressures to some extent. We have been doing this for years. It has also achieved certain results. In many cities, there are fewer and fewer bad weather that can be seen at ordinary times, and everyone is getting more and more comfortable. This is a win-win situation and the result of everyone's efforts.
