<p> because Beijing has taken the most stringent measures to determine contamination occurs at a time when there will be some pre-easterly and southerly winds, so the focus will be determined in the transmission control area channel,abercrombie pas cher, partial east and south direction,hollister site officiel, instead of seven provinces and municipalities in the region, "eyebrows beard big Bazhua."Next, determine the focus control of pollutants, PM2.5 affecting visibility because the most important component is sulfate,moncler italia, and the main source of sulfate is coal-fired.</p>
<p> Beijing and the surrounding six provinces and municipalities to take temporary measures to control air pollution. Between September 1 to September 3 date,louboutin pas cher, and launched emergency measures to reduce emissions,peuterey 2015, increase the pollution reduction efforts to the east of Beijing,woolrich outlet online, major cities in the south of the region, in particular to strengthen the coal-fired power plants, cement, steel and other overhead source control,http://www.jingdongxincheng.org/bbs/apps.php?q=diary&a=detail&did=126492&uid=29740,air jordan, to reduce the impact of pollutants senior transmitted through.Why in seven provinces and municipalities have taken stringent measures to reduce emissions after the parade and before further tightening of emission reduction measures? answer:Zhang Dawei,abercrombie soldes, director of the Beijing Municipal Environmental Protection Monitoring Center said, after August 27, Municipal Environmental Protection Monitoring Center anticipation between September 2 to September 4 date,http://www.huoxingyinli.cn/ask/forum.php?mod=viewthread&tid=7769, the weather in Beijing will be the evolution of the situation before the ridge to ridge area,abercrombie bologna, the consequences is wind turned southerly wind,http://www.vfxjournal.net/blog/item/create_form/1,barbour paris, the middle temperature rises, the possibility of the formation of inversion exists,http://www.92212.com/bbs/forum.php?mod=viewthread&tid=222152, is typical of the process of pollution accumulation."Since September 3 morning parade,tn requin, we want to assess the potential contamination of how much time,http://211.86.128.2/gjjl/Review.asp?NewsID=595, which is a risk management." Dawei said that although at the time there is a big uncertainty in forecasting, but for September 3 , the risk is there.So against such a risk, and further identify the main transmission channels.</p>
<p> Wherein step control zone in Hebei stop limit production enterprises more than 3700; within Beijing's 1927 industrial enterprises to adopt measures to limit production stopped, and during the APEC meeting an increase of 15 times. In addition, the implementation of other measures of motor vehicles with odd and even numbers during the Beijing, Tianjin, Hebei and other provinces are still part of the activities.Beijing Central Division vice president of Pan Tao said that Beijing and surrounding safeguards to reduce PM2.5 concentration played a significant effect. Numerical simulations show that August 20-September 3, Beijing 11 state-controlled sites PM2.5 concentrations decreased by about 41 percent on average; they do not take safeguard measures,peuterey uomo, PM2.5 concentration than the actual increase in the concentration of about 70%; Tianjin and Shanxi,pigalle louboutin, Henan and other neighboring provinces Montrouge air quality significantly improved synchronization,zanotti femme, the average concentration of more than 70 prefecture-level city of PM2.5 year decrease of about 40%."Pollutant reduction and environmental PM2.5 concentration ratio of the air quality protection measures implemented to improve air quality protection APEC proportion slightly higher than last year." Pan Tao said that this was mainly due between September 1 to September 3 date ,http://forum.ewcakedesigns.net/activity/activity, Beijing and surrounding provinces has launched emergency measures to reduce emissions, further tightening measures to increase the reductions.Days helpPollution diffusion met a good time"Favorable conditions for the spread of pollution is one of the important reasons for the excellent air quality." Zhang Dawei, director of the Beijing Municipal Environmental Protection Monitoring Center said that in late August to early September.</p>
<p> the Beijing summer seasonal transition period,jordan pas cher, frequent cold air activities, thundershowers more, pollutant dispersion ability,christian louboutin paris, this time of year is one of the best periods of air quality.During the "two activities" This year, Beijing is particularly favorable dispersion conditions. Dawei said, first of all from a vertical perspective, during the two events,hollister site officiel, the middle altitude of 1500 meters lower temperature than last year 1 �. If the middle is cold, so the ground hot air rises,hogan donna,http://www.05cn.com/home.php?mod=space&uid=311843&do=blog&quickforward=1&id=303615, cold air sinks middle, spread to high altitude can make the ground contaminants.On the other hand from the horizontal condition, the Beijing cold air activities during the two activities frequently this year, 52% higher frequency of north wind. Dawei said that in the north conditions, Beijing diffusion level better conditions,http://bbs.rfxt.com.cn/home.php?mod=space&uid=228650, while South winds is not conducive to the spread of pollutants.Q & AWhy further tightening measures before the parade?Forecast to September 3 or require precise control of pollution ask:Between August 20 to August 31 date.</p>
