What is the reason for the large area of yellow sand in northern 12 provinces and cities?

The yellow sand weather spans northern Xinjiang, central and western Gansu, most of Inner Mongolia and northern North China, which is the most influential in recent years. The weather is formed in a certain time and space, so the emergence of yellow sand weather needs to find out these two parts.

According to the requirements of objective existence, all on-site substances can be traced back. Because yellow sand is widely distributed in many cities, there are two conditions worth considering, one is yellow sand, and the other is the wind that can make yellow sand float. Find the source of these two conditions, and the puzzle of Huangsha weather will be broken by half. The ideas and methods of criminal investigation can actually be applied to all aspects of life, but many people can't change them.

Meteorologists pointed out that the formation of Huangsha weather was first caused by the high temperature in northwest Mongolia and the scarcity of precipitation in recent days. This provides yellow sand conditions for dusty weather. When the temperature rises and there is no rain to solidify and compact, the sand will be fluffy and uneasy, and it will be easily blown away by the wind. Then the Mongolian plateau is spring, which is easy to form cyclones. This added wind to the quicksand, which formed the phenomenon that the city was wrapped in yellow sand.
