Peak timing: effect of changes in the maximum seasonal rescaling. Difference in the median peak weeks in the reference stochastic forecast output (SFO) set, with α _max = 1.1 and α _max = 1.0, for the 500 busiest airports, as a function of the median peak week in the reference SFO set. Dots are color-coded according to the corresponding airport's climate zone. In the inset, we show the box plot indicating the distribution of the differences (in days) between the peak week of the reference SFO set and the SFO set with α _max = 1.0. Differences were fairly limited and generally fell within a period of 2 weeks.
