Ice boulders or ice balls are a somewhat rare winter phenomenon that has been seen at several locations around the world. Here in the United States, these ice balls are found almost every winter at places like Lake Michigan. Just to name a few more locations, ice balls have been seen in Russia, Finland, Sweden, and Poland. These ice balls can range in size from pea size hail to giant boulders. Ice balls form when pieces of ice break from ice sheets along the shore. These pieces of ice then follow the movement of the waves. The undulation of the waves is what makes them perfectly round.
There is one very important ingredient, cold. Not only cold air but cold water as well. The water has to be cold enough not to melt the ice. It cannot be too cold though or the ice would just freeze solid. It is the goldilocks effect, it has to be just right!
The photos attached were shared with Meteorologist Kaitlin Wright from photographer Julia Kohnke who spotted these in Jastarnia – a town in northern Poland.
