Reasons for low visibility in Wuwei

The main reasons for the low visibility in Wuwei are sandstorms and haze weather.

Sandstorm refers to a natural disaster phenomenon caused by surface soil cracking, vegetation reduction, surface water reduction, wind-blown dust and soil particles in the air in arid and semi-arid areas. Wuwei is located in the arid zone of central Gansu, where the dry land, strong wind and human activities make sandstorms more common, which will lead to reduced visibility.

Haze weather refers to the weather phenomenon formed by the mixture of suspended particles and gaseous pollutants in the atmosphere. There are some heavy industries and chemical enterprises in Wuwei city, and there are also factors such as motor vehicle emissions, which will lead to the decline of air quality and haze weather.

To solve this problem, the following measures can be taken:

1. Strengthen environmental control and reduce emissions of pollution sources, such as strengthening pollution control of heavy industries and chemical enterprises and promoting clean energy.

2. Strengthen meteorological monitoring and early warning, timely release relevant information, and guide citizens to take necessary protective measures.

3. Strengthen public education, improve citizens' awareness of environmental protection and air quality, reduce unnecessary vehicle trips, rationally use public transport and reduce pollutant emissions.

In short, the low visibility in Wuwei is mainly caused by sandstorms and haze weather. Strengthening environmental governance and public education is an effective measure to alleviate and prevent this situation.
