Weather Extremes

Ensemble-based measures of how likely and how extreme a weather event would be, given as likelihood measure (not probability).
efi: extreme forecast index
and as sot: shift of tails.
Both types of parameters are based on the Cumulative Distribution Function of the different models that make up the ensemble and refer to a certain time range over which they measure the tendency for extreme events. EFI values over 0.8 denote high likelihood for unusual conditions. SOT values signify their extremeness. Only for temperature, the shift of distribution tails is given for both the upper (default) and the lower tail (marked additionally).

NOTE: These indices cover extended time spans over which they are valid. Timing is right-aligned, i.e. the 5-day range forecast that extends from tomorrow to today+6 days should be queried at today+6 days.
