Original data: 0.0131384 °C per year 60 -
mo running mean: 0.0160371 °C per year, a 22 % increase.
We'll get rid of the noisy main signal for clarity, the 15 -
mo running mean shows its shape well enough: http://www.woodfortrees.org/plot/rss/from:1980/mean:15/plot/rss/from:1980/mean:30/plot/rss/from:1980/mean:45/plot/rss/from:1980/mean:60/plot/rss/from:1980/mean:30/mean:22/mean:17
For the analysis of all possible 12 - mo periods, we generate the annual time series of each 12 - mo period (January — December, February — January, etc.) using a 12 -
mo running mean.
(C) The probability that a negative precipitation anomaly and a positive temperature anomaly equal to or exceeding a given magnitude occur in the same 12 - mo period, for all possible 12 - mo periods (using a 12 -
mo running mean; see Materials and Methods), for varying severity of anomalies.
