Here is a plot of daily mean temperatures so far this winter at the Fairbanks Airport along with the 1981-2010 normal. Recall that the shaded area represents one standard deviation from normal, so actual temperatures that are inside the gray area could be considered as "near normal".
Interesting that you choose to use one standard deviation and the average temperature rather than the high and low observed and normals. It makes sense though, with so little diurnal trend for much of the winter.ReplyDelete
Adding daily extremes would just clutter up what I wanted to plot, and adding ± one standard deviation is an easy way to define a "near normal" range.
