	據(jù)中國氣象局統(tǒng)計，2015年入冬以來，京津冀地區(qū)經(jīng)歷了四次嚴(yán)重霧霾過程。中國氣象局預(yù)測，未來幾天，包括元旦假期在內(nèi)，京津冀地區(qū)出現(xiàn)嚴(yán)重霧霾過程的可能性較小。
According to the China Meteorological Bureau statistics, since the winter of 2015, the Beijing Tianjin Hebei region experienced four serious haze process. China Meteorological Bureau forecast, the next few days, including new year's holiday, less likely to appear serious haze process in Beijing Tianjin Hebei region.

中國氣象局環(huán)境氣象中心**預(yù)報員馬學(xué)款認(rèn)為，京津冀的霧霾日數(shù)多、過程重，既與污染物排放源強度和分布有關(guān)，也與不利氣象條件有關(guān)，污染排放是內(nèi)因，氣象條件是外因、是控制因子。
China Meteorological Bureau of environmental meteorological center chief forecaster learning models Ma believes that the Beijing, Tianjin and haze day number, weight, both and pollutant emission source intensity and distribution about, and adverse weather conditions, pollution emissions is internal and meteorological conditions is external factor, is the control factor.

今年京津冀的冷空氣強度弱，小風(fēng)日數(shù)多，導(dǎo)致污染物水平擴散能力差。此外，大氣層結(jié)穩(wěn)定，混合層**高度低，抑制了污染物的垂直擴散，空氣濕度大也利于霧霾積聚。
The intensity of cold air this year Beijing Tianjin Hebei weak wind days, leading to poor dispersion of pollutants. In addition, the stability of atmosphere, the top of the mixing layer height is low, restrain the vertical diffusion of pollutants, air humidity is also conducive to the accumulation of haze.

國家氣候中心氣候監(jiān)測室***周兵認(rèn)為，小風(fēng)日數(shù)增加、濕度偏高等加劇霧霾過程的氣象因素，與不斷增強的厄爾尼諾現(xiàn)象有所聯(lián)系。入冬以來，華北、黃淮及東北地區(qū)在對流層低層表現(xiàn)為異常的偏南風(fēng)，一方面利于東南暖氣水汽“北上”，使近地層空氣濕度增大，污染物吸濕增長，大氣能見度降低；另一方面較弱的偏南風(fēng)會造成外源污染物向京津冀地區(qū)的輸送，從而加重空氣污染程度。
National Climate Center monitoring room chief expert Zhou Bing believes that wind days increase, high humidity and haze intensified process of meteorological factors, and constantly enhance the El Nino phenomenon has contact. Since the beginning of winter, North China, Huanghuai and Northeast China in the lower troposphere performance for anomalous southerly wind, is favorable to the southeast of heating vapor "North", the near ground air humidity increases, pollutants hygroscopic growth, reduced visibility; another weak southerly wind will caused by exogenous contaminant transport to the Beijing Tianjin Hebei region, thereby increasing the degree of air pollution.

為完善霧霾預(yù)警機制，氣象局采用了“大氣環(huán)境容量”分析。國家氣候中心朱蓉博士指出，大氣環(huán)境容量是指由氣候背景條件決定的城市較大允許排放量，其系數(shù)反映了大氣對污染物的通風(fēng)稀釋和雨洗作用。據(jù)周兵介紹，今年京津冀大部分地區(qū)的大氣環(huán)境容量較近10年同期偏低60%以上。
In order to improve the early warning mechanism of haze, the Meteorological Bureau adopted the "analysis of atmospheric environmental capacity". National Climate Center Dr. Zhu Rong pointed out that the atmospheric environmental capacity is determined by the climate background of the city the maximum allowable emissions, the ventilation coefficient of atmospheric pollutants on the dilution and rain washing effect. According to Zhou Bing introduction, the atmospheric environmental capacity this year Beijing Tianjin Hebei in most areas than the same period of nearly 10 years is more than 60%.

中國氣象科學(xué)研究院大氣成分研究所副研究員劉洪利認(rèn)為，綜合評估對治理空氣污染至關(guān)重要。地面只能監(jiān)測單點和大氣底層數(shù)據(jù)，無法掌握大氣污染物垂直和水平輸送，而大氣流動必然導(dǎo)致污染物跨界傳輸。**源解析表明，北京地區(qū)污染物有將近1/3是跨界輸送的結(jié)果。因此，立體化監(jiān)測網(wǎng)絡(luò)是分析、治理霧霾的前提。
Chinese research associate Atmospheric Composition Research Institute Liu Hongli believes that the comprehensive evaluation of air pollution is very important. Only a single point ground monitoring and atmospheric data, unable to grasp the vertical and horizontal transport of air pollutants, and air flow will inevitably lead to cross-border transmission of pollutants. That the Ministry of environmental protection in Beijing Menyuan analysis, pollutant is nearly 1/3 transboundary movement results. Therefore, the three-dimensional monitoring network is the premise of analysis, governance haze.
