Liusumu weather

From March 4, 2004 to March 5, 2005, the once-in-a-decade sandstorm hit China and Mongolia, which made people unprepared. After years of ecological management, China has rarely seen "so pure" sandstorms. Strong sandstorm weather once again sounded the alarm for human beings, and ecological management has a long way to go, and ecological management coordination is indispensable. Climate and environmental problems have no national boundaries, and no country or region can be immune to them. Only by adhering to the concept of human destiny and jointly responding to the challenges of the ecological environment crisis can we truly usher in the endless blue sky and clear water.

The formation of sandstorm is influenced by many factors.

On the morning of June 5438+05, many China people living in the north ushered in a new day in the dark. In the yellow sand, the visibility in some areas is less than 500 meters, and in some areas it is even less than 200 meters. The concentration of PM 10 in the sixth district of Beijing is as high as 8 108 μ g/m3.

"This is the most extensive sandstorm in Inner Mongolia since 1978." Dabshiratu, director of the Inner Mongolia Climate Center, said that 90 of the nine national meteorological stations in the whole region1/kloc-0 had sandstorms, and two of them had extremely strong sandstorms.

Wang Yongli, deputy director of the Inner Mongolia Ecological and Agrometeorological Center, told the reporter that the dusty weather path affecting China can be divided into northwest path, west path and north path, and this dusty weather path is northwest path and west path. Through the dynamic monitoring of sandstorm by remote sensing, it can be known that the sandstorm weather process mainly started from Mongolia, which not only affected a wide range, but also moved very fast.

Song, deputy director of Inner Mongolia Meteorological Observatory, said in an interview that the intensity and scope of sandstorms are closely related to the abnormal weather phenomenon that the air turns from warm to cold in a short time. 14 When a strong sandstorm hit Mongolia in the evening, the air over Inner Mongolia in China was mainly warm, but by 5 am on 15, the strong cold air was overwhelming.

Sandstorm has not only caused a large-scale impact in northern China, but also caused many Mongolian provinces to enter a state of natural disasters. Since June, 5438+03, there has been a snowstorm in northern Mongolia and a strong sandstorm in Gobi grassland. As of 15, many provinces in Mongolia, such as Houhangai and Central Gobi, have reported 10 deaths. The strong sandstorm also caused 58 yurts and 12 1 houses and fences to be destroyed, and thousands of livestock were lost. Some transmission lines in eastern Mongolia were damaged, resulting in local power outages.
