The author:(作者)aaapublished in(发表于) 2013/12/6 12:10:00 Anhui and Jiangsu， Zhejiang and Shanghai Haze will persist-the unseen face netizens ridicule in hand-haze-pollutants
The Beijing News "Su-Wan, shocking. "Yesterday afternoon, the Central meteorological station official Micro-Blog describing a national air pollution-meteorological condition forecast map.
The figure in the Jiangsu, Zhejiang, Hebei in red, where Jiangsu South to reddish-brown, in meteorological conditions to their highest levels in six "very poor", that is, serious adverse meteorological conditions on pollutant dispersion. Is consistent with the figure, since the beginning of winter the widest range of haze are entrenched in China's Southwest, the jianghuai region.
Yesterday, a haze of fog in Southwest China and North China moderated, northern Jiangsu, Shanghai, Zhejiang, Anhui, fog and haze in the East remains acute and contamination process has lasted for 4 days. Earlier China Meteorological Administration released data reports, as of now, the national average number of days of fog and haze to 4.7 days, 2.3 per cent on annual day for the most since 1961.
The Central Meteorological Observatory chief forecaster He Lifu said, in terms of geographical distribution, this apart from in North China, has affected the whole East China, it can be said that this winter, our largest range of moderate to severe haze. In addition, long was a prominent feature of this process.
Experts estimate that from 8th to 11th, a strong cold air will affect the eastern areas of China from West to East, the morning of 9th, nightly fog haze in the East end.
Impact
"Can't hold your face"
"Dog gone dog, leash in hand, can't see rope, dog told me to do," "the furthest distance in the world, is to take you by the hand, they can't see your face" ... ... Various jokes circulated on the Internet in the near future on the haze.
Reporter, 5th in Hangzhou, on his way to work saw, limitless, surrounded by fog, visibility to less than 10 meters, characterized by vague. Wei Tianyi told journalists engaged in estate agency work, because one day you want to run multiple properties for sale, he bought a thick mask of 30 yuan. "Bought a new mask I wore it yesterday all day, got home in the evening found a mask in the filter fabric is black. ”
Doing morning exercises is usually nearby residents of Nanjing Xuanwu Lake Park "hot areas", significantly reduced the morning exercise in the day than usual. Guo, the public University of the third age from the suburbs to the city centre this morning. She said, just be fog city "choked" by not only sore throat, his eyes were uncomfortable, would like to go home now.
5th, the Shanghai Municipal meteorological fog in this winter's first Orange alert has been issued. Fog and haze weather directly led to the rising incidence of respiratory illnesses. According to the Shanghai Health Department introduced, owing to the continuing haze weather, number of people suffering from respiratory diseases in Shanghai than usual increase of around 30%. Affiliated Zhongshan Hospital of Fudan University said that some increase in respiratory illness in recent days, many patients check reasons and the air quality.
Followed is a face mask and Air Purifier sales. Taobao's average hourly PM2.5 mask shops sell more than more than more than 100 filtering face mask product. According to Xinhua News Agency

This causes widespread haze what?
Foreign and local contamination overlay
According to the Jiangsu provincial environmental protection Department Chief Engineer Liu Jianlin introduced, pollutant emission sources in Jiangsu Province has three areas: industry, especially emissions from iron and steel, cement and other large enterprises; the second is traffic, including traffic emissions; third, urban construction pollution from emissions.
Expert Tian Xudong Zhejiang Provincial environmental monitoring center, said the haze is the result of multiple factors, under the influence of contaminants in the North moved south on the one hand, on the other hand local pollutants also are on the rise, but which are more difficult to ascertain, at different times, different types of pollutants are different.
He Lifu said the Southwest appeared heavy fog and high humidity on the ground and no strong cold air, ground radiation effect, as well as local factors such as rainy.
China entered a period of high incidence of haze?
"The high incidence of haze or ten or twenty years"
Peng Yingdeng EIA experts members of the Department of environmental protection believes that China then entered a period of high incidence of fog and haze.
He said that current phase of twenty or thirty years ago, my country is going through developed countries, due to urbanization and urban layout of irrational regional haze caused by high fat.
"If the pollution of the city have no been no fundamental change, interaction between the cities in the process of urbanization are not looking, do not leave enough channel, does not take into account dilution and dispersion of pollutants structure, this situation will continue for at least 10-20 years in China. "Peng Yingdeng recommends that cities should have the buffer space between so that contaminants are diluted and spread.
Why did not affect this haze in Beijing?
Frequent cold air blowing away pollutants
In the course of this widespread haze, Beijing could "alone"? Press Statistics, since December 1, Beijing's air quality is good to moderate between pollution, one of the most serious of the 4th day, the city's moderate pollution levels, levels of pollution in the South.
Senior Engineer of Beijing professional meteorological observatory described Zhou Xiaoping, Beijing's cold air activity was frequent in the near future, came a wave of almost every 1-2 days. Affected by the cold north wind more obvious, more favourable conditions of diffusion of contaminants, pollutants cannot be easily gathered.
Experts said that haze is expected in Beijing on Saturday, but do not last too long on Sunday, a cold front will blow away haze.

新京报讯 “苏皖大地，触目惊心。”昨天下午，中央气象台官方微博如此描述一张全国空气污染气象条件预报图。
该图中江苏、浙江、河北一带为红色，其中，江苏南部为红褐色，这在气象条件中为最高级别六级“极差”，即气象条件严重不利于污染物扩散。与该图一致的是，入冬以来最大范围的雾霾正盘踞在我国西南、江淮等地区。
昨天，西南地区的大雾和华北地区的霾有所减缓，而江苏、上海、浙江北部、安徽东部的雾霾依然严重，并且污染过程已持续了4天。此前中国气象局发布数据称，截至目前，全国平均雾霾日数为4.7天，较常年同期偏多2.3天，为1961年以来最多。
中央气象台首席预报员何立富表示，从地域分布来看，此次除了华北地区以外，还影响了整个华东地区，可以说是今年入冬以来，我国范围最大的中度到重度霾天气过程。另外，持续时间长也是本次过程的一个突出特点。
专家预计，8日至11日，一股较强冷空气自西向东将影响我国中东部地区，9日早上，中东部持续多日的雾霾天气将结束。
影响
“牵着手看不见你的脸”
“遛狗不见狗，狗绳提在手，见绳不见手，狗叫我才走”“世界上最远的距离，是牵着你的手，却看不见你的脸”……各类关于雾霾的段子近期在网上广为流传。
记者5日在杭州上班途中看到，四周都是雾茫茫一片，能见度在10米以内，高楼大厦影影绰绰。从事房地产中介工作的魏天一告诉记者，因为一天要跑好多个楼盘，他特意去买了个30元钱的厚口罩。“新买的口罩昨天就戴了一天，晚上到家发现口罩里的滤布都是黑的。”
南京玄武湖公园平时是附近居民晨练的“热门地区”，当天晨练人数较平时明显减少。市民郭女士早上从郊区赶到市中心上老年大学。她说，刚进城就被浓雾“呛”到了，不但嗓子疼，眼睛也不舒服，现在就想赶紧回家。
5日，上海市气象台发布今年入冬以来首个大雾橙色预警。雾霾天气直接导致呼吸系统发病率上升。据上海市卫生部门介绍，由于持续雾霾天气，上海市患呼吸道疾病的人数比平时增加了三成左右。复旦附属中山医院表示，近几天呼吸道病患有所增多，很多病人检查的原因均和空气质量有关。
随之而来的是口罩和空气净化器销售火爆。淘宝网的多家PM2.5口罩店铺平均每小时卖出一百多件过滤口罩产品。据新华社
释疑
本次大范围雾霾原因是什么？
外来污染和本地污染叠加
据江苏省环保厅总工程师刘建琳介绍，江苏省污染物排放来源有三方面：一是工业，特别是钢铁、水泥等排放量较大企业；二是交通，包括机动车尾气排放等；三是城市建设带来的污染排放。
浙江省环境监测中心专家田旭东博士说，此次雾霾是多种因素共同作用的结果，一方面受到北方污染物南移的影响，另一方面本地污染物也在不断增多，但是受到哪个方面的影响更大很难确定，不同时段、不同类型污染物情况都不一样。
何立富说，西南地区出现大雾天气则与当地湿度大、无冷空气影响、地面辐射效应强，以及局部阴雨相间等因素有关。
中国是否进入雾霾高发期？
“雾霾高发或持续一二十年”
环保部环评常聘专家库成员彭应登认为，中国接下来将进入雾霾高发期。
他说，目前我国正在经历发达国家二三十年前的阶段，即由于城市化过程发展和城市布局不合理而导致的区域性的雾霾高发。
“假如城市的污染治理没有得到根本改观，城市化过程中不注意城市之间的相互影响，不留下足够的通道，不考虑污染物稀释扩散结构的话，这种局面在中国至少还会持续10-20年。”彭应登建议，城市之间应该有缓冲的空间，使得污染物得以稀释和扩散。
本次雾霾为何未影响北京？
冷空气频繁吹走污染物
在这次大范围雾霾过程中，为何北京这次能够“独善其身”？记者统计，12月1日以来，北京的空气质量基本处于良好至轻度污染之间，其中最严重的一天为4日，全市处于中度污染级别，南部为重度污染。
北京市专业气象台高级工程师周小平介绍，近期北京的冷空气活动很频繁，几乎每隔1至2天就来一波。受冷空气的影响北风比较明显，所以污染物的扩散条件比较有利，污染物不容易聚集。
专家表示，本周六北京预计有霾，但是不会坚持太久，周日有一股冷空气又将把霾吹跑。
