Another haze weather, the visibility to hundreds of meters. Both vehicles and pedestrians in feeling, without laughing, also do not have the bird, in such an environment, there are only pungent odor, and dark.

　　Fog, originally like smoke, such as gauze, like a gauze over the earth. How many men of letters through the ages, it has to, to dump. Now with this beautiful fog fog seems to have a relationship, and made what mistake?

　　Fog haze, seemingly "blood relationship" with the fog, but it is very different and fog. The mist, is floating in the air water vapor condensation of water droplets or ice crystals. Sometimes fog forecast sunny, sometimes the forecast of rain, fog appears to be chaotic, but as long as to master the characteristics of radiation fog, advection fog, observation, careful analysis, can accurately grasp the fog and sunny, rainy, in order to predict the weather. For the agriculture, transportation, aerospace, navigation is useful. And haze is different, it is made of the dust in the air, sulfuric acid, nitric acid, and organic hydrocarbon particles composed of gray.

　　又是一個霧霾天氣，能見度不足以百米。無論是車輛還是行人都在摸索前行，沒有了嬉笑，也無了鳥鳴，在這樣的環(huán)境里，有的只是刺鼻的氣味和滿目的昏暗。

　　霧，原本似輕煙，如薄紗，似紗巾籠罩著大地。古往今來，它曾讓多少文人墨客為之陶醉，為之傾倒。而今與這美麗的霧貌似有著一絲關(guān)系的霧霾，又犯下了什么滔天大罪?

　　霧霾，看似與霧有“血緣關(guān)系”，但它卻和霧截然不同。霧，是由浮游在空中的小水滴或冰晶組成的水汽凝結(jié)物。有時霧出預(yù)報晴，有時霧出預(yù)報雨，似乎混亂不堪，但是只要掌握了輻射霧、平流霧的特征，多方觀察，仔細分析，就能準(zhǔn)確地抓住霧與天晴、落雨的規(guī)律，以便預(yù)測天氣。這對于農(nóng)業(yè)、交通、航天、航海都有用處。 而霧霾就不一樣了，它是由空氣中的灰塵、硫酸、硝酸、有機碳氫化合物等粒子所組成的小灰粒。
