Why is it always windy in Taiyuan? Especially in spring, it blows endlessly.

This phenomenon has always existed, not entirely because of improper ecological environment protection. Improper environmental protection leads to too much dusty weather. The problem of strong wind is actually related to geographical location and seasonal alternation.

Generally speaking, in the area north of the 0-degree isotherm, when the seasons alternate, there are more winds. The formation of wind is the convection of hot and cold air. In the area north of the 0-degree isotherm, the temperature difference is relatively large, and the low temperature in winter leads to low soil temperature (the frozen soil in Taiyuan is usually 50cm, that is, the soil thickness reaches 0 degrees). After the arrival of spring, the frozen soil thaws, which makes cold air form near the ground, forming a temperature difference with the atmospheric temperature, resulting in more wind in spring.

The problem of geographical location is that Taiyuan has high latitude and altitude, and there are not many mountains in the north to block the cold air flow in the north, which forms convection with the hot air in the south at high altitude, resulting in more wind. As far as Shanxi province is concerned, the farther north, the more obvious this phenomenon is.

Lao She also wrote an article that the spring breeze in the north is about the climate of old Beijing. The phenomenon and principle are basically similar to Taiyuan. I can't remember the title of the article.
