Haze /heiz/雾霾(a kind of air pollution) 雾霾是雾和霾的统称。霾是一种天气现象，也称灰霾（烟霞），指空气中的灰尘、硫酸、硝酸、有机碳氢化合物等大量极细微的干尘粒子均匀的浮游在空中，使空气浑浊，视野模糊并导致能见度恶化，如果水平能见度小于10000米时，将这种非水成物组成的气溶胶系统造成的视程障碍称为霾(Haze)或灰霾（Dust-haze)。当水汽凝结加剧、空气湿度增大时，霾就会转化为雾。因为空气质量的恶化，雾霾天气现象便会增多，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”。2013年12月9日，一场罕见的大范围雾霾笼罩着中国，陆续有25个省份、100多座大中城市不同程度出现雾霾天气。Haze weatherWhen the haze comes, people can’t see things
