December 8th afternoon, strong northwest scenery near Beijing, scattered over the winter haze hung over the city, rare gorgeous sunset reddened the sky. A new approach to China by Ren Chenming

Comprehensive news, last week, a wide range of rare haze hangs over the China, has been a haze weather occurred in 25 provinces, more than 100 large and medium-sized city in different degree, covering nearly half the land China. But with the influence of cold air, and Eastern haze will dissipate, while Beijing's haze since yesterday afternoon began to dissipate.

The wind blowing the Jiangsu Zhejiang Beijing haze and fog will be dispersed

Meteorological Station forecast, from last night to this morning, Jiangsu, Anhui East, West, North Central Zhejiang northeast of Jiangxi such as fog, visibility less than 500 meters in some areas there is fog. Yesterday (December 8th) at night, Jiangsu, East Anhui, North Central Zhejiang, southern Shandong, Eastern Henan, air pollution, meteorological conditions of 4 ~ 5, local can reach level 6, is not conducive to the spread of pollutants in the air, the greater part area has moderate haze, wherein, parts of Northern Zhejiang, southwestern Jiangsu, and other places of Anhui southeast ministry has heavy haze.

However, affected by cold air, today, the area of fog and haze will disappear. Today in the middle and lower Yangtze River to the north area and the temperature will drop to 6 ~ 8 ℃, southern part of Northeast China, North China, South Huang Huai, Jianghuai area cooling of up to 8 ~ 10 ℃, and to the north of Huaihe area with 4 ~ 6 northerly winds. The 10 day, and a cold start effects of Eastern Inner Mongolia.

Yesterday afternoon, Beijing also blew up four or five level wind. With the strong wind, fog and haze began to dissipate, the visibility has been improved obviously. Beijing City Meteorological Station issued yesterday evening weather forecast said: 8 day and night, sunny, north wind four or five to three or four class, 9 white fine, north to South three or four to two or three levels, minus 1 to 7 DEG C. Next week, more windy weather, the temperature dropped significantly.

104 City severe "occupied" the localities have launched the emergency response

As of yesterday morning, the central meteorological station has released 3 days haze orange signal warning. In the North South continuous fog haze is different, be the first to bear the brunt in the haze. In terms of geographical distribution, in addition to outside North, the East China area are affected. According to the previous environmental protection department data show, the air quality of 104 city 20 provinces nationwide reached heavy pollution.

Haze days caused respiratory disease incidence, in the affected area, many people wearing masks travel. In the face of haze break in in full fury, the localities have sounded the emergency response. Including high-speed airport road, "stop", site work, schools, accelerate the introduction of "air pollution emergency plan" have launched. 8 morning, Kazakhstan, Beijing, Shanghai, Beijing and Hong Kong Macao highway out of Beijing direction to take temporary closure measures, Shanghai, Jiangsu, Henan, Shandong and other places have also taken a motorway partially or completely sealed road, airport passenger flights delayed or canceled.

Wuhan City Commission by letter has urged the Wuhan Iron and steel part of sintering machine, Yangluo power plant, high power, Chenming thermoelectric dry part of the unit can be taken down measures, involving the 201 foundation construction, operation, operation, dust from demolition suspension or partial suspension. In Shanghai City, has been implemented in schools. Hangzhou has decided to issue "heavy pollution emergency plan of Hangzhou City air (Trial)", to the heavy pollution, "schools, official vehicles and private cars limit line" measures as required, will be formally implemented.

 

Calm weather is "arch-criminal" sewage is fundamental reason

The central meteorological station chief forecaster Sun Jun said: due to the recent nationwide small wind, humid air, resulting in many places by the haze shrouded. From the beginning to the present, in eastern and southern China, meet the "calm weather" conditions. The wind speed near the ground layer and the humidity, pollution diffusion in the horizontal and vertical direction unfavorable in the air, because of the near surface layer with high humidity, at night and morning, the fog is relatively easy to form. If there is no obvious cold air activities, easily lead to the emergence of a wide range of fog and haze weather.

But also the expert thinks, the weather factor is the trigger and direct factors influencing the haze, but the fundamental factor is the continuing of the discharge of pollutants, the main air pollution emission total far beyond the capacity of the environment. Expert analysis, in addition to calm weather and air humidity relatively saturated, cause two pollution anthropogenic emissions is also the southern serious haze weather high-altitude strong atmospheric particle pollution transfer, more "".

As for how to "cure", Nanjing University professor Liu Hongnian said the long-term study of atmospheric pollution, to ensure smooth economic operation under the premise, to promote the structural adjustment and economic transformation, energy to greater efforts. Chinese Meteorological Bureau researcher meteorological research Beijing City experts said the haze, management should consider two aspects: one is to put the high pollution industrial emissions have been down (you can add some filtration equipment, such as industrial vacuum cleaner), two is the future in the new project, to do the pre assessment.

Haze pollution is mainly caused by sulfur dioxide, nitrogen oxides and particulate matter of the three components, these harmful gases are emitted from the enterprise production, serious damage to the quality of the air. If you want to add to prevent haze pollution, to reduce pollution, reduce air pollution, enterprises need to have a fundamental improvement in the production of dust and toxic gases, a strong environmental awareness of the enterprises generally use industrial vacuum cleaner to clean the air, filter out dust and toxic gas, can effectively improve the corporate environmental health, build better the work environment, such as an enterprise to use industrial vacuum cleaners to improve air pollution, will make us more fresh air!?
