generate_bps
(perturbator, t)¶ Generate a motion perturbation field by using the method described in [BPS06].
- Parameters
- perturbator: dict
A dictionary returned by initialize_motion_perturbations_bps.
- t: float
Lead time for the perturbation field (minutes).
- Returns
- out: ndarray
Array of shape (2,m,n) containing the x- and y-components of the motion vector perturbations, where m and n are determined from the perturbator.
