Icy Fog above Lake Superior

Residents of Duluth Harbor, Minnesota, were witness to a spectacular sight last week, as a wall of 'steam', hundreds of metres high, rose from Lake Superior.

Ice fog forms over bodies of water overlain by much colder air. Freezing fog occurs when liquid fog droplets freeze to surfaces, forming white soft or hard rime.

It tends to differ from most advective fog formed over land in that it is, like lake-effect snow, a convective phenomenon, resulting in fog which can be quite a bit denser, deeper, and looks fluffy from above.
