Baotou is dry.

Speaking of sandstorms, most northerners are familiar with the word. In the past, northern cities were prone to sandstorms in spring and autumn every year. The strong wind blew a large range of dust into the city, which seriously affected people's lives. The yellow sand all over the sky not only reduces visibility, but also greatly affects people's vision. At the same time, these dust flying around with the wind will make people feel depressed when they go out, and they will feel covered in sand. So in the past, many northerners were often troubled by dusty weather.

Afforestation has rapidly improved the sandstorm weather. In the final analysis, the sand in the soil can't be fixed because of the destruction of vegetation. At the same time, the decrease of vegetation has also led to more and more deserts. These reasons make sand blown up by strong winds in spring and autumn every year, and fly to people's places with the wind, forming dusty weather. Later, with the rise and popularization of returning farmland to forests and afforestation, people's awareness of protecting trees and vegetation became stronger and stronger, and the dusty weather gradually improved. In many northern areas, dusty weather is rare.

On the evening of March 14, a large-scale sandstorm occurred in Baotou City, Inner Mongolia. Baotou Meteorological Observatory issued a yellow warning signal for sandstorm on March 2 14, and an orange warning signal for sandstorm at 23: 50. At present, the sandstorm weather in Baotou is still going on, with the minimum visibility 100 m and the maximum wind speed of 22.3 m per second.

After research by the party group of Baotou Education Bureau, it is decided that kindergartens, primary schools and junior high schools in the city will have a one-day holiday in March 15, and senior high schools will have a half-day holiday in March 15, as the case may be. I hope parents know. Parents who have not received the notice have sent their students to the school and asked the school to make proper arrangements to ensure the safety of teachers and students in the school. The resident students asked the school to arrange self-study and cancel all outdoor activities.

The sandstorm in Inner Mongolia is very serious, which has affected people's normal life. Not only in Inner Mongolia, but also in many northern regions, such as Beijing, Hebei, Northwest China and so on. Strong dusty weather with visibility less than 500 meters appeared in some areas. The reappearance of dusty weather is also a reflection of climate and environmental changes, which reminds us to pay more attention to environmental protection, afforestation, vegetation protection and reduce the occurrence of dusty weather.
