Jouni Vainio, an ice specialist at the Finnish Meteorological Institute, said the occurrence was not common, but could happen about once a year in the right weather conditions.

“You need the right air temperature (below zero, but only a bit), the right water temperature (near freezing point), a shallow and gently sloping sandy beach and calm waves, maybe a light swell,” he said.

“You also need something that acts as the core. The core begins to collect ice around it and the swell moves it along the beach, forward and back. A small ball surface gets wet, freezes and becomes bigger and bigger.”

Nome webcam today shows no snow and no sea ice. It is bitter however. At time of this pic it was 11 F with a NE wind of 30 mph.

All change now at Nome. Snow covered and young sea ice stretches across Norton Sound.

Now you see it, now you don't. Sea ice at Nome swept away by east winds.

That implies that it's only the wind and else it's freezing cold while in  fact temps in many places of that alaskan corner are above zero today, hence it's temps + wind that do the clearing IMO
