4. Quantiles
The distribution of the various model calculations of an ensemble can also be represented by quantiles. In a spatial depiction, the minimum wind gusts forecast by the ensemble for each location in Switzerland is determined and represented with colour coding. Any number of quantiles can be depicted in this way, as shown in the figure below with the 25% and 75% quantile (25%/75% of the gusts predicted by the ensemble with lower wind speeds than the value shown in colour), as can the maximum value from all ensemble forecasts. The closer the values of the various quantiles lie to one another, the more certain the forecast.
