earthkit.meteo.extreme.xarray.sot_unsorted

earthkit.meteo.extreme.xarray.sot_unsorted(clim, ens, perc, eps=-10000.0, clim_dim=None, ens_dim=None)

Compute Shift of Tails (SOT) from climatology percentiles (sorted) and ensemble forecast (not sorted).

Parameters:

  • clim (xarray.DataArray) – Model climatology (percentiles). The reduction dimension is set by clim_dim.

  • ens (xarray.DataArray) – Ensemble forecast. The reduction dimension is set by ens_dim.

  • perc (int) – Percentile value (typically 10 or 90)

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

  • clim_dim (str, optional) – Name of the climatology/quantile dimension in clim.

  • ens_dim (str, optional) – Name of the ensemble/member dimension in ens.

Returns:

SOT values.

Return type:

xarray.DataArray
