Where did the mud in Beijing come from when the sandstorm struck?

When it comes to sandstorms, maybe southerners don't have much idea about this word, because there are almost no sandstorms in the south. But the north is different, especially in Inner Mongolia. First, let's take a look at what a sandstorm is. Sandstorm actually refers to a weather phenomenon, specifically refers to the strong wind that rolls up the dust on the ground and makes the horizontal visibility less than one kilometer. In dusty weather, if the sandstorm is serious, people will see the yellow sky, and the air is filled with the smell of dust. Before long, people or other things exposed to the outside will be covered with dust, and serious sandstorms will also affect the take-off of flights. In March of 20021year, a severe sandstorm occurred in the north. Beijing experienced a sandstorm in April, but it also rained? Mud rain? , what's going on?

1. At the same time as the sandstorm struck, Beijing suffered from thunderstorm weather, so it appeared? Mud rain? .

In March of 20021year, the sandstorm in the north was the most serious in recent ten years. The sandstorm weather in March affected more than a dozen provinces in the north. Sandstorm weather not only affects people's normal travel, but also leads to a sharp decline in air quality and low visibility. People can smell the thick dust in the air. On April 15, the sandstorm struck again, and this time, while the sandstorm struck, Beijing happened to encounter a thunderstorm. When dust hits a thunderstorm, you can imagine the final result. What is it? Mud rain? Falling from the sky.

Second, what about this time? Mud rain? What effects does the weather have on people?

It might be better if it's just a sandstorm, but when a sandstorm meets a thunderstorm, it's no longer a layer of dust but a layer of mud. People who travel outside will not fall on their bodies with dust or raindrops, but with dirt. So this muddy rainy weather has also brought a lot of trouble to many people.
