WebCloud cover is often referred to as "mist" when encountered on surfaces of mountains, whereas moisture suspended above a body of water, cleared or marsh area is usually called "fog". One main difference between mist and fog is visibility. The phenomenon is called fog if the visibility is 1 km (1,100 yd) or less. In the United Kingdom, the definition of fog is … WebFog, mist and cloud are all formed when air cools to its dew point (the term is self-explanatory). Water in the air may condense onto a cold surface such as the ground, a house roof or on to small particles in the air (known in the trade as condensation nuclei). At ground level the "cloud" is called fog or mist depending upon the visibility.
WebSo called radiation fog is formed in calm conditions with clear skies. So air at the ground is cooled and can't absorb moisture. And in the earliest hours of the day we get morning fog. So called steam fog forms over bodies of water. Cold air passes over warmer water, and rising moisture condenses to fog. WebDescription Mist and Fog are the terms used to describe low visibility caused by water droplets suspended in the air. Mist is a term used to describe visibility of greater than 1 km while Fog is the term used when visibility is less than 1 km.
