pysteps.noise.interface.get_method

pysteps.noise.interface.get_method(name)

Return two callable functions to initialize and generate 2d perturbations of precipitation or velocity fields.

Methods for precipitation fields:

Name Description
parametric this global generator uses parametric Fourier filtering (power-law model)
nonparametric this global generator uses nonparametric Fourier filtering
ssft this local generator uses the short-space Fourier filtering
nested this local generator uses a nested Fourier filtering

Methods for velocity fields:

Name Description
bps The method described in [BPS06], where time-dependent velocity perturbations are sampled from the exponential distribution
