Fog is sometimes described as a ground-level Stratus cloud, since that’s the lowest of the main clouds. However, it often forms quite differently. In this photograph, it appears that this is valley fog for the most part, which is a variation of "radiation fog" after a cool and clear night, wherein the cold, foggy air sinks downhill and gathers further below. This classic example was spotted over Pauatahanui Inlet, north of Wellington, New Zealand.
