Where does fog come from? Fog is nothing but cloud on the ground.It forms in the same way as a cloud forms.In short, fog comes from the condensation of water vapour near the ground.Calm wind,ground inversion and clear skies on the previous night help the formation of fog particularly in the early morning.

1.3 Fog harvesting Fogs are defined as a mass of water vapor condensed into small water droplets at, or just above, the Earth's surface. The small water droplets present in the fog precipitate when they come in contact with objects.

- In both fog and cloud, the dispersed phase is a liquid and the  dispersion medium is air (gas). The only difference between them is  that the fog is formed in the region clo … se to earth while clouds  are formed in the upper layer of the atmosphere. 12 people found this useful.

- Fog commonly occurs when air rapidly cools, causing condensation to form. Care should be taken when driving or walking in foggy conditions. Freezing fog may cause ice crystals to form on trees. Fog fformation is similar to cloud formation, but fog forms close to the ground.

Fog Evaporation fog or steam fog forms over bodies of water overlain by much colder air; this situation can also lead to steam devils forming. Lake effect fog is of this type, sometimes in combination with other causes like radiation fog.

Where Does Fog Come From? Advection fog occurs when warm air moves in over a cooler land surface. This happens often along coastlines, for example, when warm ocean breezes blow in over cooler land. The land cools the warm air below the dew point, and fog forms. Upslope fog occurs when warm air passes over the upward slope of a cool mountain.

Fog season Though it's more frequent in June due to more rain. It is not generally true that fog season in a given area is during Fall or Winter (the cooler months); for example, the Japanese coast of the Pacific Ocean has a dense fog season from May to August.

- Do a pairing weave to secure the slath. Pairing is a type of weaving that uses two weavers, creating a secure base for your basket. Separate the weavers and bend them to the right over the adjacent spoke. Place one weaver over the spoke and one weaver under the spoke and gather them on the right side of the spoke.

- For instance, rain can cool and moisten the air near the surface until fog forms. Or, as is more often the case, infrared cooling of a cloud-free, humid air mass at night can lead to fog formation-this is called radiation fog.

- Added to Your Check-Ins. The Fog (1980) Legend says that Antonio Bay was built in 1880 with blood money obtained from shipwrecked lepers, which no one believes. On the eve of the town's centennial, many plan to attend the celebrations, including the murdered lepers.

Smog The word smog was coined in the early 20th century as a portmanteau of the words smoke and fog to refer to smoky fog, its opacity, and odour.[1] The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid 20th century.

- Radiation Fog. This type of fog forms at night under clear skies with calm winds when heat absorbed by the earth’s surface during the day is radiated into space. As the earth’s surface continues to cool, provided a deep enough layer of moist air is present near the ground, the humidity will reach 100% and fog will form.

What is the dew point, and how does fog form? As we mentioned earlier, fog happens when the temperature and dew point are equal or within a degree and the air becomes saturated. The fog comes in two varieties: Ground fog usually begins on clear, calm nights. But, first, during the day, you need the sun to warm the ground.

- Smog is a combination of the words smoke and fog and classically is a mixture of sulfu dioxide (from coal burning) and smoke. Nowadays it comes mainly from vehicle emissions rather than heavy coal burning. It can include the following:

The Green Fog Green Mist. A green cloud formed in the skies above The Overthere. The cloud began to descend upon our land like a plague from the gods above. From it's green core the face of death began to form. It was of no god neither our people, not the Shissar knew of. It opened it's giant maw and spoke in tongues unknown. The Shissar tried to use their knowledge of magics both light and dark to overcome the evil fog that spewed from its mouth but all was in vain.

How Does Fog Form? This valley fog, really just a type of radiation fog, results from cold, dense air draining down mountain slopes at night, collecting in the valley floors, then forming as any other radiation fog described above. Incidentally, let's dispel a myth. Fog does not burn off, per se. As solar energy heats the ground near the fog's edge, vertical mixing brings drier air into the fog's edge, evaporating it. A typical ground fog will dissipate first at its edges, where its depth is more shallow, working its way toward the thicker center of the fog.

Where does fog come from? Fog is defined as a cloud in contact with the ground that reduces visibility to less than 1km. Fog forms when the difference between the air temperature and dewpoint is 5°F (3°C), or less. Fog is a cloud in contact with the ground.

Where Does Fog Come From? If the temperature of the air sinks below its dew point, water vapor will condense around dust in the air to form fog. Advection fog occurs when warm air moves in over a cooler land surface. This happens often along coastlines, for example, when warm ocean breezes blow in over cooler land.

The Many Flavors of Fog Moreover, Tardif found that there are more variations in the types of fog in the Northeast than on the West Coast. He categorizes fog in five ways: Precipitation fog: After a light rain, surface moisture evaporates, allowing fog drops to develop near the surface. This was the most common type of fog in the New York area. Sea fog: Forming over cold water and then propagating onto land, this type forms often at JFK airport, which is near the ocean.

- fog(noun) droplets of water vapor suspended in the air near the ground. fog, fogginess, murk, murkiness(noun) an atmosphere in which visibility is reduced because of a cloud of some substance. daze, fog, haze(verb) confusion characterized by lack of clarity.

Freezing fog What is freezing fog? Freezing fog forms in the same way as normal fog when the land cools overnight under clear skies. If there are clear skies, the heat radiates back into space leading to cooling at the earth's surface.

Fog season Visibility in this photo is less than 500 feet. The fog season is a season of fog that occurs in some places, because of special meteorological and topographical characteristics, after a rainy period. The fog season is usually based in the cooler months (late autumn, winter and early spring).

- Advection fog occurs when a warm, moist, air mass flows across a colder surface. The air mass is cooled from below by the colder surface and, if the temperature of the air mass is reduced to the dew point, then fog forms.

Where does fog come from? What happens then is that the air molecules condense in tiny droplets of water that forms the clouds and ... the fog. Fog appears usually when there is an inversion; i.e. the air above is warmer than under and therefore doesn't rise. During a clear sky night, heat from the ground radiates away and get colder. That's why you often see fog early in the morning of a clear sky and little wind.

How Fog Forms The two common types are steam fog and frontal fog. Steam fog forms when cold air moves over warm water. When the cool air mixes with the warm moist air over the water, the moist air cools until its humidity reaches 100% and fog forms.
