Q

Steam fog cause

A

Forms when cold air moves over warm water, cool air mixes with warm moist air the moist air cools and the humidity reaches 100%

Q

Frontal Fog Causes

A

Warm raindrops evaporate to cooler drier air layer near the surface as it evaporates the humidity reaches 100% and fog forms

Q

Radiation Fog causes

A

Happens usually on calm clear nights, during the day UV rays heat up the surface at night the UV rays are released from the ground and the surface cools to dewpoint
