The weather is really bad at the moment there is fog everywhere and really hard to see, we were really wondering what course`s the fog. Thanks.

Fog is CAUSED by too much moisture in the atmosphere which joins together to form minute water droplets and these are the fog - dense moisture which, when freezing CAUSES ice surfaces on the road

Are you British? Cause you spelled it the way British people pronounce "causes".

Most likely a thermal inversion where ground-level air cools, forms fog and stagnates in place.

The country is covered with high pressure which in the summer gives us good weather. In the winter it holds down all the condensation from the ground and without wind it doesn't disperse. Here in Gloucestershire it has all gone away since 1pm
Happy Christmas.

It's a mixture of warm air from the ground,and cold air in the sky.
The two combining,is what causes the fog.

Would love to help you but do not understand what the question is. or is it why does frog cause fog? Is that is?

It is coursed by retards who can't spell in the atmosphere.

Fog can form in a number of ways, depending on how the cooling that caused the condensation occurred:

Radiation fog is formed by the cooling of land after sunset by thermal (infrared) radiation in calm conditions with clear sky. The cool ground produces condensation in the nearby air by heat conduction. In perfect calm the fog layer can be less than a metre deep but turbulence can promote a thicker layer. Radiation fog is common in autumn and usually does not last long past sunrise.

Ground fog is fog that obscures less than 60% of the sky and does not extend to the base of any overhead clouds. However, the term is sometimes used to refer to radiation fog.

Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled. It is common as a warm front passes over an area with significant snowpack. It's most common at sea when tropical air encounters cooler higher-latitude waters, or in areas of upwelling, such as along the California coast. The advection of fog along the California coastline is propelled onto land by one of several processes. A cold front can push the marine layer coastward, an occurrence most typical in the spring or late fall. During the summer months, a low pressure trough produced by intense heating inland creates a strong pressure gradient, drawing in the dense marine layer. Also during the summer, strong high pressure aloft over the desert southwest, usually in connection with the summer monsoon, produces a south to southeasterly flow which can drive the offshore marine layer up the coastline, a phenomenon known as a "southerly surge", typically following a coastal heat spell. However, if the monsoonal flow is sufficiently turbulent, it may instead break up the marine layer and any fog it may contain.

Steam fog, also called evaporation fog, is the most localized form and is created by cold air passing over much warmer water or moist land. often causes freezing fog, or sometimes hoar frost.

Precipitation fog (or frontal fog) forms as precipitation falls into drier air below the cloud, the liquid droplets evaporate into water vapor. The water vapor cools and at the dewpoint it condenses and fog forms.

Upslope fog forms when winds blow air up a slope (called orographic lift), adiabatical cooling it as it rises, and causing the moisture in it to condense. This often causes freezing fog on mountaintops, where the cloud ceiling would not otherwise be low enough.

Valley fog forms in mountain valleys, often during winter. It is the result of a temperature inversion caused by heavier cold air settling into in a valley, with warmer air passing over the mountains above. It is essentially radiation fog confined by local topography, and can last for several days in calm conditions. In California's Central Valley, Valley fog is often referred to as Tule fog.

Ice fog is any kind of fog where the droplets have frozen into extremely tiny crystals of ice in midair. Generally this requires temperatures at or below minus 30 degrees Fahrenheit (-35C), making it common only in and near the Arctic and Antarctic regions. It is most often seen in urban areas where it is created by the freezing of water vapor present in automobile exhaust and combustion products from heating and power generation. Urban ice fog can become extremely dense and will persist day and night until the temperature rises. Extremely small amounts of ice fog falling from the sky form a type of precipitation called ice crystals, often reported in Barrow, Alaska. Ice fog often leads to the visual phenomenon of light pillars.

Freezing fog occurs when liquid fog droplets freeze to surfaces, forming white rime ice. This is very common on mountaintops which are exposed to low cloud. It is equivalent to freezing rain, and essentially the same as the ice that forms inside a freezer which is not of the "frostless" or "frost-free" type.

Artificial fog is artificially generated fog that is usually created by vaporizing a water and glycol-based or glycerine-based fluid. The fluid is injected into a heated block, and evaporates quickly. The resulting pressure forces the vapor out of the exit. Upon coming into contact with cool outside air the vapor forms a fog - see fog machine.

Garua fog is a type of fog which occurs at the western coast of Chile. The normal fog produced by the sea travels inland, but suddenly meets an area of hot air. This causes the water particles of fog to shrink, making unusually small water droplets that cause fog. Garua fog is nearly invisible, yet it still forces drivers to use windshield wipers.
