Additive Model Perturbations Scaled by Physical Tendencies for Use in Ensemble Prediction
Tellus: Series A, Dynamic Meteorology and Oceanography, 2023 Imperfections and uncertainties in forecast models are often represented in ensemble prediction systems by stochastic perturbations of model equations. In this article, we present a new technique to generate model perturbations.

Stochastic E-L Wave Theory: Perturbation Techniques [PDF]
The Journal of the Acoustical Society of America, 1973 Although stochastic E-L (Eulerian-Langrangian) wave theory does not require random perturbation techniques in principle to provide solutions, in practice, ensemble expectations are usually resolved by perturbing the random medium. The fundamental concepts for the evaluation of wave functionals are first treated in one dimension, then a central limit ...
