Chinese official data shows that there are 12 weather and dust weather in China from January to April, and 267 cities in 27 provinces across the country have a total of 4892 days of sand and dust, which is the most in the same period in the past five years.
According to the surging news report, Jiang Huohua, deputy director of the Ecological Environment Monitoring Department of the Ministry of Ecology and Environment, announced the above data at a regular launch conference on Monday (May 29).
Jiang Huohua pointed out that several large sand dust processes that have occurred this spring this year have affected the sand and dust from northern China.Both strong sand and dust in Beijing in March originated in southern Mongolia.
Jiang Huohua quoted expert analysis that Mongolia's contribution to Beijing's sand and dust concentration can reach 70 %, and contribute more than 50 % of the sand and dust concentrations in northeast China and other areas of the central and eastern regions.
He also said that the Chinese meteorological department has established a relatively complete sand and dust weather monitoring and forecast system, and has initially formed the ability to monitor and forecast the heaven and earth that affects air quality.
In terms of ground monitoring, on the basis of real -time monitoring particles in the automatic monitoring of air quality in 1,734 countries in China, the existing 1225 districts, counties, towns, and towns, including Inner Mongolia, Inner Mongolia, Inner Mongolia, which are near the sand and dust sources in the northwest,Monitoring stations have been connected to the state, and the county -level cities that have been in the Sand and Dust Source District in the northwest are initially covered. This is a "ground sentry" that monitors the real -time monitoring of air quality.
In terms of satellite remote sensing monitoring, the Ministry of Environment of China has established the Sand and dust weather satellite remote sensing monitoring business system. It has a full -day satellite remote sensing monitoring technology combined with multi -source remote sensing data such as polar rail satellites and static satellites.Ability, this is the "eyes" of "tracking" sand and dust weather.
Chinese State Councilor and Foreign Minister Qin Gang met in Beijing on May 1 with Mongolian Foreign Minister Butzze.The Chinese Ministry of Foreign Affairs announced that the two sides agreed to strengthen the prevention and control of sandstorms and jointly promote sustainable development.
