earthkit.meteo.extreme.array.sot_func(qc_tail, qc, qf, eps=-0.0001, lower_bound=-10, upper_bound=10)

Compute basic Shift of Tails (SOT) using already computed percentiles.

Parameters:

  • qc_tail (array-like (npoints)) – Tail percentile value (99% or 1%) Model climatology

  • qc (array-like (npoints)) – Upper or lower percentile (at 90% or 10%) Model climatology

  • qf (array-like(npoints)) – Upper or lower percentile (at 90% or 10%) Ensemble forecast

  • eps ((float)) – Epsilon factor for zero values

  • missing ((float)) – missing points values where denominator is zero

Returns:

SOT values

Return type:

array-like (npoints)
