Haze weather analysis(雾霾天气分析报告英文版)

Haze weather analysisEarly this year, continuing fog and haze swept most of our country. Fog and haze was breakout frequently, which is why urban atmospheric environment, the health of residents, traffic safety, and agricultural production will have serious repercussions. Besides, the formation of fog and haze is difficult to dissipate.The haze weather was selected in the first National top ten weather and climate events in 2011.“Haze” this new word gradually into the public eyes, and has aroused public concern about environmental protection.1.The haze occurred in beginning of 2013The fog and haze was exploded every year in our country. However, the haze that occurred in beginning of 2013 not normal---not only like the wind passing in general, but also visited the most parts of China for sometimes.Haze comes to our country in the east, northeast, and southwest part of the region, including the most polluted place of northern coastal areas. There’s a serious impact onquality of people’s lives, travel safety, physical health. There’s a wide range of hazecontamination from the area which the northeast to northwest, more sever in large areas.The haze profoundly affects people’s normal life. The hospital Pneumology Departmentbeen overcrowded in the big city. What’s more, haze is most prevalent during the winter months. As the more vehicles on the road, the series of chain reactions were happened, just like traffic accidents and traffic delays just when the spring peak,According to reports indicate that because of the large range of haze, Beijing, HK and Macao highway and Changsha—Xiangtan section on January 13, 8:00 Am to 17:00 of nine hours, was happened more than 40 traffic accidents. Beijing, Tianjin, Shijiazhuang,Nanning and other cities in the number of major hospital waiting for treatment soared by 7—8 times in a few days.2.Natural disasters and Man-made disastersThe fundamental reason of haze is that massive outbreak from the motor vehicles, industrial emissions.Some experts put this climate pollution accident as a “natural disasters andMan—made disasters”. Natural disasters means that haze accident break out with somesituation which extreme cold, the atmosphere still not flow, pollutants are difficult todissipate; Man—made mean that the emit large quantities of pollutants on the ground under the spread of extremely adverse contamination conditions.In the most heavily polluted January 12, 2012, there was more than 30 cities’ air quality index over 300, belong heavily polluted. Pollution effects render contiguous toBeijing, Tianjin and other cities aren’t immune.3.Haze weather causedEvery day we live in such an environment can’t help but ask, why Beijing, Tianjin became heavily polluted areas. During the winter vacation, back to my hometown— Tianjin,I particularly felt by haze enveloped the castle a dead, lifeless.Some experts believe that the objective reason is the recent air not flow down, contaminants are tightly stuffy in the atmosphere. Human reason is that the history hasproved that the region in China’s northern Gold Coast industrial development, pollutants in the air only to rise, for this reason also increased haze pollution levels and duration.Asking haze come from, some experts pointed out that the haze in Beijing, Tianjin, respectively from the “Beijing car, Tianjin oil, Hebei coal”. Floating in Beijing nitrateparticles in the air most of the cars produced by the Beijing material transformation. In the morning rush hour, the values of nitrogen oxides is high, form nitrate particles floating in the air is difficult to spread in the static stability under high humidity conditions. That’s visible particles formed haze until particles grow to more than 400 nm. As an industrial city in Hebei province, coal produces sulfur dioxide and dust emissions. Tianjin rich oil reserves and its related industries organic emissions is huge.4.Tianjin haze analysisDuring winter holiday just when the haze weather break out, backing to my hometown—Tianjin, my felt very obvious.Walking on the street, I deeply felt unban air not a substance to see, touch or small anymore. For example, in Tianjin tower scenic I can’t see the top of the tower spire through the thick haze. In the park, can’t hear the laughter of children, old people not figure ofmorning exercises, can’t smell the flower bloom in the fragrance of the soil. We just saw thatsome people walked on the street with “heavily armed” bow rapid shuttling prepared by the haze of dreams.5.Is the opposite of the development and environmentThrough analysis Beijing— Tianjin and other haze areas, we find that the air pollution seriously areas are often gathered in the industrialized areas. Excessive discharge of industrial waste causes a lot of pollutants float in the air, if coupled with small wind, pollutantsbecomes haze if it won’t spread timely. Haze weather is catastrophe that damage humanhealth and destruct human life. Therefore, it is particularly important to protect theenvironment.Development is the eternal pursuit of mankind theme, according to we have only one—sided pursuit of economic development thus punished by nature in the past, we must take the measures comply with sustainable development, we can promote steady and rapid economic development without sacrifice the environment. We can only protect our common home, in order to reproduce the sound on this fertile land.6.Control MeasuresAs the development of the energy industry, the environment is more terrible. Fortunately, many of people realized that we will kill our future by development industry like that.Since reform and opening, the energy industry is development rapidly. At the same time, there are a large amount of weak point is revealed.On the one hand coal dominated energy resources in our nation. Thus a large number of coals will make a variety of harmful gas emissions and cause air pollution. The other hand, the unbalanced development of China’s electricity power, China’s energy demand and energy resources presents reverse distribution pattern.As China’s future energy demand continues growing and change in the pattern of world energy, China’s energy development mode change is urgent.The party’s 18 put forward the “two hundred years” goal. Development can’t be without energy. Coal isn’t only China’s basic energy, but also in the long term is China’s leading energy. Therefore we should science and economical use resources and find alternative green energy. Use electrical energy with clean and efficient features, taking theelectricity power energy balance as an important support for the resources balance.。

雾霾英语演讲PPT课件

Automobile exhaust
Automobile exhaust is another important cause of smog. The exhaust emissions from automobiles contain a large amount of pollutants such as hydrocarbons, nitrogen oxides, and carbon monoxide. These pollutants react chemically with oxygen in the atmosphere to form secondary particulate matter, which in turn leads to the generation of haze.

Fog_haze_weather雾霾天气

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。
