How fog is formed
WebDescription Steam Fog, also known as Steaming Fog, Evaporation Fog, Frost Smoke or Arctic Sea Smoke, occurs when evaporation takes place into cold air lying over warmer water. It is usually quite shallow. It is named by analogy with the condensed vapour or steam which appears above water which is heated. Invisible vapour is given off from the … WebFog. Fog forms when the difference between air temperature and dew point is less than 2.5 °C (4.5 °F). Dew Point = 65.5 degF. Mist. Mist forms when the relative humidity is greater than about 70\%. Rain. Often, rain will be falling from clouds where the humidity is 100\% into air with a lower humidity.
