How did the blue sun appear in the sky after the sandstorm in Beijing?

Northern China was hit by a sandstorm. After the sandstorm in Beijing, the blue sun appeared in the sky, which was a magical scene. In the sky of Beijing, after a sandstorm, a blue sun appeared. In fact, it is not the real blue sun, but because the white sun rays are scattered by suspended particles in the air, scattering a lot of red and yellow rays in the sun rays, while the blue rays are not. Therefore, the sunlight will appear blue. In fact, what we see is only a beam of slightly blue sunshine, not the sun.

How did the sandstorm weather come in recent days? With the continuous strengthening of social modernization in China, China has also adjusted its overall development strategy. In recent years, China has paid more and more attention to the balance and protection of environment and ecology. As early as the founding of New China, China started the construction of the Three-North Shelterbelt. Today, the Three-North Shelterbelt in China has played a great role, which has greatly slowed down desertification and filled the land of China with green blocks.

The sandstorm actually came from Mongolia and originated in northern Mongolia. Due to less precipitation, high temperature and dry land in northern Mongolia, and windy weather caused by atmospheric cyclone and cold air over Mongolia, this sandstorm weather appeared. Because of this climate, there have even been deaths in Mongolia, which have caused great losses to Mongolia.

Therefore, the northern part of China has been greatly affected, and dusty weather has appeared in all northern provinces, even affecting South Korea and the Korean Peninsula.

Some people say that sandstorms will enter China because there are gaps in the shelterbelts in China. This statement is very unscientific, because the average sandstorm is almost tens of meters high, and the number of shelterbelts is simply out of reach.

Now cold air comes with dusty weather, so everyone should pay attention to protect themselves.
