FOGS [8 records]

Record 1 2018-02-20

English

Subject field(s)
  • Atmospheric Physics
CONT

Stratus build-down fog(cloud-base lowering fog, inversion fog) [is] one of [the] five distinct fog types, calling it fog resulting from the lowering of the cloud base. This lowering of the cloud base occurs in the absence of precipitation, so is fundamentally different from precipitation fog.... a clear majority of stratus build-down fogs [begin] during the nighttime hours, which implies a relationship to IR [infrared] radiative cooling.

French

Domaine(s)
  • Physique de l'atmosphère
CONT

[Le] brouillard d'affaissement de stratus (brouillard de nuages bas, brouillard d'inversion) [est] un brouillard résultant de l'abaissement de la base des nuages. Cet affaissement se produisant en l'absence de précipitations, le brouillard d'inversion est fondamentalement différent du brouillard de précipitations. [La] grande majorité des cas de brouillard d'affaissement de stratus [commencent] durant la nuit, ce qui implique une certaine relation avec le refroidissement radiatif infrarouge.

Record 4 2011-01-18

English

Subject field(s)
  • Photography
OBS

Chemical fog caused by oxidation will often disappear if the image is bleached in a permanganate bleacher.

CONT

Chemical fog covers all types of fog caused by side reactions in the developer and fixer.

OBS

The term "oxidation fog" is more often replaced by "chemical fog" among professional photographers, [but "chemical fog"] is a generic for different types of fogs.

Key term(s)
  • oxydation fog

French

Domaine(s)
  • Photographie
DEF

Noircissement indésirable qui apparaît sur le film ou sur le papier, causé par une réaction chimique associée à la présence [d'oxygène dans l'air].

OBS

Les photographes utilisent davantage le terme «voile chimique», mais ce terme englobe différents types de voiles.

OBS

Pour l'observation, la définition et l'équivalent, l'auteur s'est inspiré des ouvrages intitulés «La photo de A à Z» et «Lexique du cinéma d'amateur».

Record 5 2004-06-23

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

Fog formed when water vapor is added to air which is much colder than the vapor’s source; most commonly, when very cold air drifts across relatively warm water.

CONT

Steam fog [is] a type of advection fog that is produced by evaporation when cool air passes over a warm wet surface and the fog rises, giving the appearance of steam.

CONT

Fogs formed by evaporation [evaporation fogs]-when saturation of air in contact with the ground occurs by addition of water vapor. Two types, steam fog and frontal fog.

CONT

Evaporation fog occurs when you get cold air advection over warm water or warm, moist land surfaces resulting in fog formation as water evaporates into the cold air. This type of fog is sometimes called steam fog or sea smoke.

OBS

steam fog: Also called sea smoke when it occurs over the ocean [a body of saltwater]. An example is Arctic Sea Smoke.

OBS

According to some authors: "steam fog" is also called sea smoke (arctic sea smoke, antarctic sea smoke), frost smoke, water smoke, sea mist, steam mist.

OBS

Steam fog is commonly observed over lakes and streams on cold autumn mornings, as well as in polar regions.

OBS

frost smoke: Same as steam fog. ... [Frost smoke has also another meaning:] Steam fog ... is sometimes confused with "ice fog" but its particles are entirely liquid. At temperatures below -29°C (minus 20°F), these may freeze into droxtals and create a type of ice fog that may be known as "frost smoke".

OBS

Note, also, that although advection of air is necessary to produce steam fog, it differs greatly from an advection fog in the usual sense, which is caused by warm, moist air moving over a cold surface.

Key term(s)
  • warm water fog

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
DEF

Brouillard dans lequel la saturation est amenée dans une masse d'air froide et stable, par évaporation rapide à la surface de l'eau chaude sous-jacente.

CONT

Ce brouillard d'évaporation se forme fréquemment au-dessus de chenaux (ou de clairières) de formation récente, ou sous le vent de la lisière des glaces et peut persister lorsque se forment la bouillie neigeuse ou la jeune glace.

CONT

Parmi les brouillards dont l'origine est essentiellement un enrichissement de l'air en vapeur d'eau, on identifie en particulier les brouillards d'évaporation associés à l'évaporation d'une surface chaude et humide (mer, lac, marais) dans de l'air plus froid.

OBS

Les deux notions désignées par les termes anglais «frost smoke» et «steam fog» sont interreliées très étroitement. Nous n'avons pas été en mesure d'établir de distinctions parfaitement nettes entre elles, et entre leur pléiade de synonymes, les différents auteurs se contredisant. Nous avons retenu les distinctions établies par la source PROME (Standard Dictionary of Meteorological Sciences : English-French/French-English, par Gérard-J. Proulx).

OBS

Les marins donnent le même sens aux mots «brume» et «brouillard» et ils emploient surtout le premier mot.

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

Radiation fog which occurs over wet ground after the passage of a cold front.

CONT

As with the prefrontal fog, postfrontal(cold front) fogs are caused by falling precipitation. Fogs of this type are common when cold fronts with east-west orientations have become quasi-stationary and the continental polar air behind the front is stable. This type of fog is common in the Midwest.

Key term(s)

Record 7 2004-04-07

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

Fog in advance of a warm front, caused mainly by the increase of moisture in the underlying cold air resulting from the evaporation of pre-frontal rain.

CONT

Prefrontal(warm front) fogs occur in stable continental polar(cP) air masses when precipitating warm air overrides the colder air. The rain raises the dewpoint in the cP air mass sufficiently for fog formation. Generally, the wind speeds are light, and the area most conducive to the formation of this type of fog is one between a nearby secondary low and the primary low-pressure center. The northeastern area of the United States is probably the most prevalent region for this type of fog. Prefrontal fog is also of importance along the Gulf and Atlantic coastal plains, the Midwest, and in the valleys of the Appalachians.

Key term(s)
  • pre frontal fog

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
DEF

Brouillard formé à l'avant d'un front chaud, principalement dû à l'augmentation de l'humidité de l'air froid par évaporation de la pluie préfrontale.

Key term(s)
  • brouillard pré-frontal

Spanish

Campo(s) temático(s)
  • Fenómenos meteorológicos, climáticos y atmosféricos
