What is evaporation fog?

Evaporation fog, also known as steam fog, occurs when cold air moves over warmer water. As the warm water evaporates, the moisture-laden air rises and cools, leading to condensation and the formation of tiny water droplets. This type of fog is commonly seen over lakes or rivers during the fall and winter months when the air temperature drops significantly. The resulting fog can create a beautiful, ethereal landscape but can also reduce visibility.
