: Perturbations#
Perturbation methods are used for perturbing the input data they are provided, typically with some random noise. This is commonly done to perturb initial state fields when creating ensemble forecasts.

Bred Vector perturbation method, a classical technique for pertubations in ensemble forecasting. |
