	Fog - Wikipedia, the free encyclopedia
		Fog is particularly hazardous at airports, where some attempts have been made to develop methods (such as using heating or spraying salt particles) to aid fog dispersal.
		Salt fog (or salt-fog) is characteristic of coastal atmospheres; the water droplets of this form of fog, formed by evaporated seawater, carry in solution microscopic particles of salt.
		Artificial fog is artificially generated fog that is usually created by vaporizing a water and glycol-based or glycerine-based fluid.

	BBC - Weather Centre - Features - Understanding Weather - Fog
		Fog is a common problem here in the UK as we have four different types: radiation fog, advection fog, hill fog and coastal fog.
		After dawn, fog tends to disperse because it is 'burnt off' by the incoming solar radiation, some of which penetrates the fog and reaches the ground.
		Hill fog or upslope fog, as its name implies, is formed as mild moist air is forced to ascend a hill or mountain range.

		Fog emerges from the armature and from under a circular bench, creating a cool oasis and revealing the ebb and flow of the wind.
		The vortex was made visible by fog pumped thro ‚ugh the floor and illuminated by a combination of natural light and electronically controlled lights that slowly cycled through various colors.
		Dense fog swirls down into a large funnel-shaped chamber set into the floor of the new planetarium and forms a vortex suggestive of a spiral galaxy.

	advection fog - Hutchinson encyclopedia article about advection fog (Site not responding. Last check: 2007-10-22)
		Advection fog occurs when two currents of air, one cooler than the other meet, or by warm air flowing over a cold surface.
		Radiation fog forms through rapid heat loss from the land, causing condensation to take place and a mist to appear.
		Fog formed by warm moist air meeting a cold ocean current or flowing over a cold land surface.

	Gamasutra - Features - "Volumetric Rendering in Realtime" [10.03.01]
		Fog is a cloud of water vapor consisting of millions of tiny particles floating in space.
		An alternative way to create fog is to model a polygonal hull that represents the fog, and to compute the area of fog for each pixel rendered on the scene.
		However, the shaft of fog along a ray can be closely approximated subtracting the w depth a ray enters a fog volume from the w depth of the point it leaves the volume, and multiplying by some constant.

	Maui Fog Research
		Despite the extremely high rainfall in the area, evidence from previous studies (Juvik and Ekern, 1978; Scholl et al., 2002) indicates that fog may be a substantial part of the water budget of these forests, especially at altitudes between 600 and 2000 meters.
		Fog is the major source of moisture during much of the year, as rainfall occurs mostly during large winter storms.
		Samples of fog, rain, soil water, tree sap, (and stream water at the windward site) were collected for stable isotopes, and amounts of fog and rain precipitation and throughfall were measured.

		The use of a fog fluid that was composed of water and glycols was heralded by the industry with an award in technical achievement from the Academy of Motion Picture Arts and Sciences.
		Fog fluids used in these processes are made from a series of glycols mixed with water.
		When fog is constricted, it tends to recondense into fluid reducing the output and creating an unwanted residue.

	1.3 Fog harvesting
		Fog harvesting efficiencies were found to be highest during the spring and summer months, and lowest during the winter months.
		Thus, a minimum fog season duration of half a year might serve as a guideline when considering the feasibility of using this technology for water supply purposes; however, a detailed economic analysis to determine the minimum duration of the fog season that would make this technology cost-effective should be made.
		Caution is required to minimize impacts on the landscape and the flora and fauna of the region during the construction of the fog harvesting equipment and the storage and distribution facilities.

	BBC - Weather Centre - Features - Weather Basics - Fog
		Fog forms in many different ways, but generally the air near the ground can hold its moisture for longer, so water droplets condense to form fog.
		Fog usually clears soon after dawn as the sun heats up the air again, allowing it to hold more moisture.
		This 'Advection' fog often forms by the coast, especially in spring and summer when there is a greater difference between the temperatures of the sea and land.

		Fog is defined as a thick cloud of water droplets, 0.00039 to 0.00156 inches in diameter, suspended in the atmosphere at or near the earth's surface and reducing visibility to below half a mile.
		And if fog lights are mounted in an air dam and you drive across the desert a lot, they get essentially sand blasted and all the little pits affect the flow of light and the light pattern.
		Another important consideration when mounting fog lights is that they be mounted rigidly, so the beam stays pointed the way it's aimed, as opposed to dancing over tar strips on the road and the like.

		Fog moves on, just like life does, i think that he was comparing the poem to life.
		I also feel that the poet isn't referring to the fog when he writes "It sits looking over harbour and city on silent haunches and then moves on" I beleive that he is referring to the cat watching the city.
		For one thing, no cat is mentioned in the poem, only the fog which is being compared to a cat and which is the subject of the poem.

		In a hilly area, the cool air settles into the valleys and therefore fog forms in the valleys while hilltops may be clear.
		Although you could argue that if there are light winds over both a flat and hilly area, the winds could prevent fog formation in the flat area, but fog could still form in one of the valleys of the hilly area that are sheltered from the wind.
		This type of fog forms exclusively in areas of sharp upslopes, such as the area around Los Angeles, or the eastern slope of the Rockies.
