Why is "Fog" considered "Fog" all over the world except in So Cal where it is referred to as "Marine Layer"?

Elitest mentality? Just doesn't fit in a sentance very easily either.
"Damn! It's Marine Layerery as hell this morning!"
"My mind is in a Marine Layer this morning. I need more coffee. Wonder if the skies are sunny in Ann Arbor?"
"I haven't the Marine Layeriest of a clue as to HOW Michigan could lose every single game this season."

It's called fog when it's regular fog (haven't lived until you've tried to drive in "tule fog", and it's called a marine layer when it's offshore moisture that is carried over land by onshore winds. The only place it's called a marine layer is right on the coast. It's also not really fog at all, as it it's seldom at ground level, but several hundred feet off the ground and appears more like it's overcast (though there's no cloud system passing through).

C'mon Sadovin...it's fog man. Mixed with Mexican cookouts. We all know it's true.

To me, fog is ground clouds. What they call a marine layer is no where near the ground.

Saying a marine layer is no different than any other kind of fog is like saying fog is no different than any other kind of cloud. Calling it a marine layer (which is a meteorological term, not a California term) describes the nature of the clouds and their source -- marine moisture at low altitudes, but not at ground level. It really has no more in common with inland fog than it does with a thunder cloud.

So Sadovin, what is it when the MS River is foged over and on both, the eas & west bank, it's clear? Is that fog or marine layer?
How does marine layer form?

Cold air off the ocean passing over land . Living in the LA Basin for a few years I get "it" with what Sadovin is saying. In VA we get it at times with a NE wind blowing off the ocean. As the day progresses it goes away with heating from the sun........

PJ, we get this in the Gulf with south winds....it's still called fog.
Where it's at in the sky is irrelevant. We get ground fog, dense fog, upper level fog, over water and over land....just like So Cal.

Sometimes you can look at a satellite picture of California and you can see the "clouds off the coast" and they form up to the land and just stop. It forms over water, passes over the land when it cools and retreats/disipates as it warms. Normally fog is created by warmer air from the water passing over a colder air mass. Ie the effect of the Gulf Stream on England. The Gulf of Mexico is normally warmer than most other bodies of water.

This happens more often over water. The fog then gravitates to the land for various reasons.

From wiki.........
A marine layer is an air mass which develops over the surface of a large body of water such as the ocean or large lake in the presence of a temperature inversion. The inversion itself is usually initiated by the cooling effect of the water on the surface layer of an otherwise warm air mass. As it cools, the surface air becomes more dense than the warmer air above it, and thus is trapped below it. The layer may thicken through turbulence generated within the developing marine layer itself. It may also thicken if the warmer air above it is lifted by an approaching area of low pressure. The layer will also gradually increase its humidity by evaporation of the ocean surface, as well as by the effect of cooling itself. Fog will form within a marine layer where the humidity is high enough and cooling sufficient to produce condensation. Stratus and stratocumulus will also form at the top of a marine layer in the presence of the same conditions there.
In the case of coastal California, the offshore marine layer is typically propelled inland by a pressure gradient which develops as a result of intense heating inland, blanketing coastal communities in cooler air which, if saturated, also contains fog. The fog can last until midday when the heat of the sun is frequently strong enough to evaporate it. An approaching frontal system or trough can also drive the marine layer onshore.
A marine layer will disperse and break up in the presence of instability such as may be caused by the passage of frontal system or trough, or any upper air turbulence which reaches the surface. A marine layer can also be driven away by sufficiently strong winds.

Here try this one.......
A marine layer is a dense mass of cool, moist air which accumulates over the surface of large bodies of water, especially oceans. It is caused by a temperature inversion, meaning that the air close to the ground is colder, rather than warmer, while warm air above the marine layer presses down on it, preventing it from dissipating. Marine layers are responsible for the fog which plagues many coastal communities, and they can also cause unusual phenomena, like campfire smoke which flattens out, rather than drifting upwards.
The formation of a marine layer can take place in a number of ways. Generally, air becomes saturated with moisture, causing it to become cool and dense, or it gets cold overnight and in cloudy conditions. Warmer air above will force the cold air back down, creating an inversion. A mass of warm air can also drift in over cooler air, trapping it so that the marine layer often gets colder and more dense as a result. If the air becomes saturated enough, the marine layer will turn foggy. These masses of cool air can also be quite large, extending well up into the atmosphere.
People in coastal communities are familiar with the marine layer in the form of an ominous pile of fog and clouds which hovers on the horizon, waiting for an opportunity to move onto shore. As conditions on shore cool, the marine layer drifts in, saturating the coastline with fog and sometimes light drizzle. Sometimes, inland communities can be extremely warm and sunny; this actually traps the marine layer even further, by creating a bubble of warm air enclosing the cooler, sluggish marine layer.
Many communities which experience marine layers also struggle with smog, particulate matter which pollutes the air. Smog can become trapped in the marine layer, and the same temperature inversion which causes the marine layer can also create a dense mass of smog. In some cases, smog may get so bad that citizens are warned that they should not go outdoors, as the air quality is extremely poor. Temperature inversions can also occur in valleys or deep depressions in the surface of the Earth, especially if they have large water features, which is why Mexico City struggles with smog, even though it is in the middle of Mexico.
Strong winds can break up a marine layer, often by pushing it onto shore so that the sun can dissipate it. Storms may also disperse marine layers, as will turbulence in the air
