写一篇关于雾霾的出现原因和应对方法的英语作文 带上翻译 要原创 简单点的

Well,what is earth? What is haze? The meteorological definition of fog is that it isa collection of liquid water droplets or ice crystals suspended in the air ator near the earth’s surface, reducing the visibility to less than 1 km. Thisdefinition is quite abstract. There is another poetic visual explanation-cloudis the fog floating in the sky, while fog is the cloud descending in the land.
Thedefinition of fog giving by China Meteorological Administration in The standard of surface meteorogicalobservation is that it’s a common muddy atmospheric phenomenon where agreat amount of tiny dry particles evenly suspend in the sky reducing thevisibility to less 10 km, because of haze, light objects in the distance giveus an illusion of slight yellow or red ones, dark objects give us an illusionof slight blue ones. The distinctive difference between fog and haze isrelative humidity. The low visible atmospheric phenomenon where the relativehumidity is over 95% is called fog, lower than 80% one is called haze, and theone in between is the mixture of fog and haze (mostly haze).
Haze can cause a visual effect ofobscuration because it has reduced the visibility, due to the effect of lightscattering and absorption through the haze particles in the sky. Among them,light scattering of particles plays the leading role. The umbrella term ofparticles is Total Suspended Particulates (TSP), whose component PM 2.5 isfrequently cited since 2011.
PM 2.5 is paid much attention to not onlybecause it is Suspect Zero, but also because it does great harm to humanhealth. In human body, PM 10 centralizes in larynx and nasal cavity. It iserased through sneezing, coughing and rhinorrhea. The particles between 2.5 and10 micron congest in trachea, while PM 2.5 would travel deep into the lung.
Thereis no doubt that there are more and more “Haze City”636f7079e799bee5baa6e997aee7ad94330 in China. A foreignphotographer took a panorama of Chinese skyline. Dense fog and haze totallyenvelop the whole city, leaving only two high chimneys erecting through the fogand haze. The white smoke constantly emitting from the chimneys seems tothicken the haze layer. It seems that the picture is showing us a patheticprediction that Chinese cities will face great obstacles in harnessing the hazeproblem for a long time in the future, and it will take a long time for thehaze suspecting in the sky above Chinese cities to disappear.
