Morphology

ice + fog

The phrase denotes a type of fog made of ice rather than liquid droplets, which a B1 learner can infer directly from combining 'ice' and 'fog'. This noun–noun composition follows a transparent, cross-linguistically common compounding pattern, so the specific meteorological nuance is predictable from the constituents.

Etymology

Ice fog comes from the simple image of ice and fog together: in very cold weather the air fills with 'tiny bits of ice' that float close to the ground and look like fog. So, ice fog means 'a dense winter fog of ice particles'.
