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.

　　 又是一个雾霾天气，能见度不足以百米。无论是车辆还是行人都在摸索前行，没有了嬉笑，也无了鸟鸣，在这样的环境里，有的只是刺鼻的气味和满目的昏暗。

　　 雾，原本似轻烟，如薄纱，似纱巾笼罩着大地。古往今来，它曾让多少文人墨客为之陶醉，为之倾倒。而今与这美丽的雾貌似有着一丝关系的雾霾，又犯下了什么滔天大罪?

　　 雾霾，看似与雾有“血缘关系”，但它却和雾截然不同。雾，是由浮游在空中的小水滴或冰晶组成的水汽凝结物。有时雾出预报晴，有时雾出预报雨，似乎混乱不堪，但是只要掌握了辐射雾、平流雾的特征，多方观察，仔细分析，就能准确地抓住雾与天晴、落雨的规律，以便预测天气。这对于农业、交通、航天、航海都有用处。 而雾霾就不一样了，它是由空气中的灰尘、硫酸、硝酸、有机碳氢化合物等粒子所组成的小灰粒。
