h/t Glenn in WUWT Tips & Notes.
OK, it’s early in the ice coverage season for the Great Lakes. But we keep hearing how warm it is over in Eastern Canada….
What does this chart show? The ice is off to a very good start with the amount being rather like it was back in 1972. A whole lot of heat is coming out of the water (as that ice is made) and going into the air. Just another example of why temperature is a lousy proxy for heat flow. If you click on the graph you get a gigantic version.
Water temps are interesting too. Looks to me like warm rising in the middle, cold sinking at the edges, as the thinner edges cool quicker. Interesting. Like you can almost see the heat pump out of the lake..
I know it will change very slowly, but here is a ‘live version’ so folks can check up on it from time to time:
