mist

A hydrometeor consisting of the suspension in the atmosphere of microscopic-sized water droplets - with diameters of several tens of microns (between 50 and 200 μ m) - or humid, hygroscopic particles (cloud-droplet embryos). It can be considered a particular case of fog, in which horizontal visibility is equal to or greater than one kilometer, up to ten. In aeronautical weather reports it is coded as mist (BR) when the aforementioned horizontal visibility is between 1 and 5 km. Mist clouds the air, giving it a grayish or bluish tint, not as whitish as fog, where the diameter of the droplets is larger, as is their concentration. While the relative humidity of the air in a fog is between 90 and 100%, in a mist it is usually between 80 and 90%. It is common to speak indistinctly of mist or haze, although sometimes both phenomena are differentiated, not by their consequences (reduced visibility) but by their nature. Is also considered a lithometeor (formed by suspended solid particles), although it is most commonly identified with a maritime mist.
