Fog has nothing to do with the time of the year, and is possible all year long.
If you ever hear the weather radio, telling you that it is a certain temperature, and the "dew point" is a lower temperature. The "Dew Point" they refer to, is the temperature at which the air will have fog start to form.
The thing that does that, is the fact that cold air has less ability to hold moisture than warm air. If the air cools, the same amount of moisture, will become a higher percentage of the maximum amount the air can hold. If the air gets cooler, down to the "Dew Point" then the humidity level will get near 100%, and tiny droplets of water will start to form. These drops are so small, they can be suspended in the air, and not fall as rain. This is what we see as fog.
The lowlands get fog more often, because the ground and vegetation may give off more moisture, adding to the humidity level. There are many factors that can effect the conditions that cause fog, but most often it is the warm moist air being cooled to the point it can't hold the moisture any longer.

DevinFog in lowlands during December is caused by the cooling of air close to the ground, which can lead to the condensation of water vapor into tiny droplets. This process is more likely to occur in low-lying areas where cooler air can settle, creating optimal conditions for fog formation.

Why you see fog even in the lowland on early mornings of December?
Because of the clouds when it was December the clouds condensed and to heavy so they form fogs it covers the lowland and the highland.
What is the refractive index of fog?
Fog is made out of water droplets in suspension in the air. The refractive index of these droplets is 1.3330. However the body of fog as seen on mass is opaque (enough of it will stop light) and opaque substances do not have a refractive index.
What is fog made thicker by smoke?
Fog can be made thicker by the presence of smoke, as the particles in the smoke can serve as condensation nuclei for water droplets to form around. This can result in the fog becoming more opaque and reducing visibility even further.
Clouds close to the earth are called?
Clouds close to the earth are called fog. Fog forms when the air near the ground cools and reaches its dew point, causing water vapor to condense into tiny water droplets. Fog can reduce visibility and is commonly seen in the morning or evenings when temperatures are cooler.
What is fog intensity?
Fog intensity refers to the density or thickness of fog in a particular area. It is a measure of how much visibility is reduced due to fog, with higher intensity indicating thicker fog and lower visibility. Fog intensity can vary depending on factors such as temperature, humidity, and wind conditions.
