Foghazeweather雾霾天气

Fog haze weather, causing a large area of low visibility condition in the city. In the morning or at night when relative humidity is larger, forming fog; Rising temperatures, humidity drops during the day, gradually into a haze. This phenomenon is due to weather and pollution emissions. Since January 9, 2013, the central and eastern regions in serious smog and pollution of the day, the national meteorological center to upgrade to the yellow fog blue warning alert, 13 to 10 Beijing released even when the weather first haze orange alert in Beijing, in mid-january, Beijing's air pollution index is close to 1000. From the northeast to the northwest, from north China to central result in huanghuai, jiangnan region, there were a wide range of severe and severe pollution.雾霾天气，造成城市里大面积低能见度的情况。

在早上或夜间相对湿度较大的时候，形成的是雾；在白天气温上升、湿度下降的时候，逐渐转化成霾。

这种现象既有气象原因，也有污染排放原因。

2013年1月9日以来，全国中东部地区陷入严重的雾霾和污染天中，中央气象台将大雾蓝色预警升级至黄色预警，13日10时北京甚至发布了北京气象史上首个霾橙色预警，一月中旬，北京的空气污染指数接近了1000。

从东北到西北，从华北到中部导致黄淮、江南地区，都出现了大范围的重度和严重污染。

Similarities between fog and haze are visibility obstruction. But the reasons for the formation of fog and haze and conditions but there's a big difference. Fog is floating in the air of a large number of small water droplets or ice crystals, forming conditions requires a higher water vapor saturated. Appeared fog air humidity, air relative humidity is 100%, or closer to 100%. Appear when the fog effective horizontal visibility to less than 1 km. When effective 1-10 km horizontal visibility as mist. Fog has with the daily variation of air humidity and appear sooner or later, the more common or add thick, relatively reduce and disappear phenomenon during the day. A haze when air is relatively dry, air relative humidity under 80% usually. Its formation is due to a large number of tiny particles of dust, smoke, salt crystals evenly suspended in the air, make effective horizontal visibility to less than 10 km air mixed corrosion phenomenon, symbols for "up". The diurnal variation of the haze is not obvious in general. When air masses without big changes, the air mass is stable, continue to appear for a long time, sometimes sustainable more than 10 days. Because the haze and mist, dust, flying sand, dust, smoke, such as a weather phenomenon, floating in the air for all the large number of very small dust particles and smoke that effective horizontal visibility to less than 10 km. Sometimes makes meteorological professionals are difficult to distinguish. Must be combined with the weather background, air condition, air humidity, color, smell and other factors, such as satellite monitoring to comprehensive analysis and judgment, to correct conclusions, and fog and haze weather phenomenon can transform each other sometimes.雾和霾相同之处都是视程障碍物。

但雾与霾的形成原因和条件却有很大的差别。

雾是浮游在空中的大量微小水滴或冰晶，形成条件要具备较高的水汽饱和因素。

出现雾时空气潮湿，空气相对湿度常达100%或接近100%。

出现雾时有效水平能见度小于1KM。

当有效水平能见度1－10KM时称为轻雾。

雾有随着空气湿度的日变化而出现早晚较常见或加浓，白天相对减轻甚至消失的现象。

出现霾时空气则相对干燥，空气相对湿度通常在80%以下。

其形成原因是由于大量极细微的尘粒、烟粒、盐粒等均匀地浮游在空中，使有效水平能见度小于10KM 的空气混蚀的现象，符号为"∞"。

霾的日变化一般不明显。

当气团没有大的变化，空气团较稳定时，持续出现时间较长，有时可持续10天以上。

由于阴霾、轻雾、沙尘暴、扬沙、浮尘、烟雾等天气现象，都是因浮游在空中大量极微细的尘粒或烟粒等影响致使有效水平能见度小于10KM。

有时使气象专业人员都难于区分。

必须结合天气背景、天空状况、空气湿度、颜色气味及卫星监测等因素来综合分析判断，才能得出正确结论，而且雾和霾的天气现象有时可以相互转换的。

Wen: dealing with the fog haze days in action makes people see hope [5][5] on January 24 to 29, 2013, premier wen jiabao at the zhongnanhai hosted three conferences, listen to the people from all walks of life to the government work report (draft) "the opinions and Suggestions of China's urban low-carbon JingJiWang, wen said recently the haze of the weather affect people life and health are, we should take effective measures to accelerate the industrial structure and layout adjustment, promote energy conservation and emissions reduction, the construction of ecological civilization, let people see the hope by action.温家宝:应对雾霾天用行动让人民看到希望[5][5]2013年1月24日至29日，国务院总理温家宝在中南海主持召开三次座谈会，听取各界人士对《政府工作报告(征求意见稿)》的意见和建议中国城市低碳经济网温家宝表示，最近的雾霾天气对人们生产生活和身体健康都造成影响，我们应该采取切实有效的措施，加快推进产业结构和布局调整，推进节能减排，建设生态文明，用行动让人民看到希望Li talk about air pollution control: we have to do somethingSince January 10, 2013, China's central and eastern regions last fog haze weather, political bureau of the CPC central committee and vice premier li keqiang on 15th morning at present at the meeting when it comes to air pollution problems. [6]He pointed out that in the process, we honestly to the public in a timely manner and the data of PM2.5. Accumulation is a long-term process, solve problems and need a long-term process, but we must do something! On one hand we should strengthen environmental law enforcement and other relevant aspects of the work, the other party alerting the public to enhance self protection. It need to set up a national consciousness, to universal participation, common governance. [6] According to China's urban low-carbon JingJiWang reporter understanding, Chinese vice premier li keqiang was in Beijing to attend the 2012 annual meeting of the international cooperation on environment and development committee, said that the environment problem has become the important livelihood issues, the Chinese government will increase the intensity of pollution treatment, will be in beijing-tianjin-hebei, etc in 2012 and publish PM2.5 monitoring information. "People want to live and work in peace and contentment 'income, also want to sky blue green water net, as a government, has the responsibility to mobilize various aspects strength, increase the intensity of pollution treatment. Since this year, China will in beijing-tianjin-hebei, Yangtze river delta, the pearl river delta area, as well as municipalities, provincial capitals, PM2.5 monitoring and information will be released. It is an indicator, but has landmark significance, also has a spur to our work." [6]Li admitted that resources are relatively insufficient and limited environmental capacity has become China's basic national conditions, as the development of short board, and promote the building of ecological civilization is to break the bottleneck constraints. , he says, the 12th five-year period, China will transfer the money 3.4 trillion RMB to the fields of ecological environmental protection, energy conservation and emissions reduction will be the structure adjustment and the innovation transformation of the important breakthrough point, to make the carbon dioxide emissions per unit of GDP in 2015 than in 2010 dropped by 17%..李克强谈空气污染治理：我们必须有所作为2013年1月10日以来，我国中东部地区持续雾霾天气，中共中央政治局常委、国务院副总理李克强15日上午在出席会议时谈及空气污染治理问题。
