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
