The Yoyo Goes On
Now that the next "warm phase" of the winter is well underway for Interior Alaska, here's an updated plot of standardized daily temperature anomalies at Fairbanks. For the most part, it's been either one or the other. Since November 1st, 54% of the days (55 out of 102) days have had an average daily temperature 1.0 or more standard deviations from the mean. If temperatures were normally distributed (which in general is not the case), we would expect about 32 such days. In the El Niño winter of 2009-10, Nov 1-Feb 10 had only 24 days ±1.0 standard deviation from the daily normal. Got all that?
