- Definição2
- The meteorological condition in which the horizontal visibility at the earth’s surface is less than 1000 m because of suspended small droplets or ice crystals in the air. Relative humidity in this case is generally 100% but not less than 95%. Fog is formed by the cooling of the air by contact and mixing or, occasionally, through saturation of the air by increasing water content.
