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 [BPS2006], where time-dependent velocity perturbations are sampled from the exponential distribution
