用英语描述雾霾

随着空气质量的恶化，阴霾天气现象出现增多，危害加重。中国不少地区把阴霾天气现象并入雾一起作为灾害性天气预警预报。统称为“雾霾天气”。其实雾与霾从某种角度来说是有很大差别的。譬如：出现雾时空气潮湿；出现霾时空气则相对干燥，空气相对湿度通常在60%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 With the deterioration of the air quality, haze weather phenomenon to appear increasing, harm aggravated. In some areas of China the haze weather phenomenon incorporated into fog together as a severe weather warning forecast. Collectively referred to as "fog haze weather". In fact the fog and haze in some point of view there's a big difference. Such as: appear fog air moisture; Appear when air is relatively dry haze, air relative humidity usually under 60%. The forming reason is due to a large number of very small dust particles, smoke particle, such as YanLi evenly suspended in the air, make effective horizontal visibility less than 10 km air mixed corrosion phenomenon 吸入过多可致死亡 Haze in the suction of respiratory tract after harmful to human body, long-term intake may can lead to death.
