steam fog; sea smoke
A meteorological phenomenon where cold air moves over warmer water, causing evaporation and condensation that looks like steam rising from the surface. Often seen over lakes or the sea in autumn and winter.
This morning, steam fog was hanging over the lake.
On winter mornings, the sight of sea smoke rising from the sea surface is magical.
Compound of 蒸気 (steam, vapor) and 霧 (fog). The reading じょうきぎり follows standard on-kun compounding.
