Sandstorm weather in Dunhuang, how is the sandstorm formed?
Before July this year, extreme weather occurred in many places in China. The rainstorm in Henan has not subsided, Hebei has suffered heavy rainfall, and typhoon fireworks have also appeared in various provinces along the way. While fighting floods in China, catastrophic floods have also occurred in the European continent. These successive bad weather are all warnings from nature, and we should stop destroying the natural ecology.
The sandstorm weather in Dunhuang, Gansu Province is also a disastrous weather. According to the report, the wind force of this sandstorm may reach level 6 or above. So how is the sandstorm formed? This is closely related to our human activities.
The main conditions for the formation of sandstorms need windy weather, because only strong winds can drive sandstorms and dust movements. However, sandstorm weather cannot be formed by strong winds alone, just as typhoon landing will bring strong winds but will not form sandstorm weather. Another indispensable condition is that there is a dust source where the strong wind passes, which is a solid medium produced by dust storms.
Man-made activities will destroy the local environment to a certain extent, leading to dust accumulation and creating opportunities for dust storms. Such as deforestation, overgrazing and over-cultivation. These people think that activities will expose the soil, and with the passage of time, these exposed soils will gradually become loose and sandy, and will be blown up when encountering strong winds, thus forming sandstorm weather.
The emergence of sandstorms is largely the result of our long-term destruction of the natural environment, which also brings early warning to people in nature. Protecting the earth's environment means protecting our own homes. Let's work together to make our home green and healthy.
