Fog Flashcards
(14 cards)
What is Radiation Fog?
Fog formed by radiation cooling on clear nights with high relative humidity and light winds
Radiation fog typically occurs under specific atmospheric conditions.
What are the typical wind speeds associated with Radiation Fog?
1 to 5 KT
These light winds contribute to the formation of radiation fog.
When is Radiation Fog most likely to be present?
Shortly after sunrise
The conditions at this time are conducive to the formation of radiation fog.
How thick is Radiation Fog typically?
A few hundred feet thick
The thickness can vary, but it is generally not very deep.
What happens to Radiation Fog as wind speed increases?
The fog lifts and eventually dissipates
Increased wind speed and warming from the sun contribute to the dissipation of the fog.
Fill in the blank: Radiation Fog is formed by _______ cooling.
[radiation]
Radiation cooling is the process that leads to the formation of this type of fog.
True or False: Radiation Fog is usually dense and thick.
False
Radiation fog is typically patchy and not very thick.
What is Radiation Fog?
A type of fog that forms when the ground loses heat through radiation, cooling the air near the surface.
Commonly occurs on clear nights with calm winds.
What is Advection Fog?
Fog that forms when warm, moist air moves over a cooler surface, causing the air to cool and condense.
Often seen along coastlines.
What is Upslope Fog?
Fog that occurs when moist air is lifted over a topographical barrier, cooling as it rises.
Common in mountainous regions.
What is Frontal Fog?
Fog that develops along a front when warm air rises over colder air, leading to condensation.
Typically associated with weather fronts.
What is Steam Fog?
Fog that forms when cold air passes over warm water, causing water vapor to condense into fog.
Often observed over lakes or rivers in autumn.
What is Ice Fog?
Fog that occurs in very cold temperatures, where water vapor sublimates directly into ice crystals.
Common in polar regions and during severe winter conditions.
What is Industrial Fog?
Fog that is formed as a result of pollution, particularly in urban areas, where industrial emissions contribute to moisture condensation.
Can have significant impacts on air quality.
