FDDs DMI N80 thru Feb 15

FDDs DMI N80 thru Feb 8

Means and mean error

Three sets of synthetic data:

Set L is a linear function increasing in value with each year.  Set R is a random normal distribution, and Set S is a sine function.  Do they RMSEs in and of themselves tell us anything about these functions? No.  Only by looking at the actual data would we be able to see this.

Someone forgot to tell the arctic to wait for Karl to bust the pause.

I was going to add text and arrow for "Curry jumps shark" but there would have been too many arrows and the graph too cluttered.

Annual FDDs per DMI N80

Annual Total Accumulated Freezing Degree Days
(August 1st thru May 31st)

Does not include this freezing season as it is not yet complete.

So, what's happening during the summer months of June & July?

Odd, melt season temperatures are actually *decreasing* - now why would that be?
