Fog/Stratus/VisibilityOther Fog

Fog can also form in place, without advection. If winds are light, a strong inversion can form over the pack ice. When the pack ice is melting, melt ponds provide moisture. Evaporating melt ponds and boundary layer mixing eventually lead to saturation, forming fog. Like advection fog, this condition persists until clearing occurs due to turbulent mixing from strong winds or a frontal passage.
