What is fog bank?

A fog bank is a thick layer of fog that extends along the surface of the Earth and can cover a large area. Fog banks usually form when warm, moist air moves over a cool surface, causing the air to cool and condense into droplets.

Fog banks can reduce visibility significantly, making it difficult for drivers and pilots to see clearly. They can also create hazardous driving conditions, as they can make road surfaces slippery and increase the risk of accidents.

Fog banks are more common in coastal regions, where cool ocean waters can cool the air and create the conditions for fog formation. They can also occur in valleys and low-lying areas, where cold air can be trapped and create a temperature inversion that leads to fog formation.

Fog banks can have a significant impact on the local climate, as they can block sunlight and reduce temperatures, leading to cooler and more humid conditions. They can also have important ecological effects, as they can provide moisture for plants and animals and help regulate local water cycles.
