Ensemble prediction

AlgoComponents dedicated to computations related to the Ensemble Prediction System.

class vortex.nwp.algo.eps.Svect(*args, **kwargs)

Singular vectors computation.

class vortex.nwp.algo.eps.CombiSVunit(*args, **kwargs)

Combine the unit SV to create the raw perturbations by gaussian sampling.

class vortex.nwp.algo.eps.CombiSVnorm(*args, **kwargs)

Compute a norm consistent with the background error and combine the normed SV to create the SV perturbations.

class vortex.nwp.algo.eps.CombiIC(*args, **kwargs)

Combine the SV and AE or breeding perturbations to create the initial conditions.

class vortex.nwp.algo.eps.CombiBreeding(*args, **kwargs)

Compute a norm consistent with the background error and combine the normed SV to create the SV perturbations.

class vortex.nwp.algo.eps.SurfCombiIC(*args, **kw)

Combine the deterministic surface with the perturbed surface to create the initial surface conditions.

class vortex.nwp.algo.eps.Clustering(*args, **kwargs)

Select by clustering a sample of members among the whole set.

class vortex.nwp.algo.eps.Addpearp(*args, **kw)

Add the selected PEARP perturbations to the deterministic AROME initial conditions.
