The Ice Balls of Lake Michigan

It is a particularly cold night here and I thought I'd post something related.

Just a couple of weeks ago, during the previous appearance of the polar vortex, someone posted these ice balls that had appeared in lake Michigan.




Apparently, they are created when "small fragments of floating ice act like seeds, with layers upon layers of supercooled lake water freezing around them as the balls churn in the waves. Wind then pushes the ice concretions onshore."

What Condition 1 Weather in Antarctica Looks Like

We're expecting some pretty bad weather for the next two days here where I am.
Temperatures are going to drop significantly, falling to -25oC at some point.
In Minnesota it's going to reach -50oC, but -25oC is already too much for someone not used to it.

At least the situation isn't going to be like what they face in Antarctica during condition 1 weather.

Condition 1 weather, as I've learnt from Wikipedia, means:

Windspeed over 55 knots (60 mph / 96kmh)

Visibility less than 100 feet (30 meters)

Wind chill below −100 °F (−73 °C)

Description: Dangerous conditions; outside travel is not permitted.

And this is what it looks like. Filmed at McMurdo station, Antarctica.




I'm surprised they're separated from the outside environment by just two pretty normal-looking doors.
