Is there a difference between foggy days and foggy days?
Haze: Dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles in the air can also make the atmosphere turbid, blur the vision and make the visibility worse. If the horizontal visibility is less than 65,438+000m m, the visual distance obstacle caused by this non-aquatic aerosol system is called haze or dust haze, and the Hong Kong Observatory calls it haze. Generally, when the relative humidity is less than 80%, the poor visibility caused by blurred vision is caused by smog.
Haze: Haze is a combination of fog and haze. Because of the deterioration of air quality, cloudy days have increased and the harm has increased. In many areas of our country, the smog weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather". When the relative humidity is between 80% and 90%, the deterioration of visibility caused by blurred vision is caused by the mixture of haze and fog, but its main component is haze. The thickness of haze is relatively thick, which can reach about 1-3 km. Because the smog is composed of dust, sulfuric acid, nitric acid and other particles, the longer the scattering wavelength, the more the light ratio, so the smog looks yellow or orange-gray.
