Additive Model Perturbations Scaled by Physical Tendencies for Use in Ensemble Prediction

Michael Tsyrulnikov, Elena Astakhova, Dmitry Gayfulin

Imperfections and uncertainties in forecast models are often represented in ensemble prediction systems by stochastic perturbations of model equations. In this article, we present…

Regularization of the ensemble Kalman filter using a non-parametric, non-stationary spatial model

Michael Tsyrulnikov, Arseniy Sotskiy

The sample covariance matrix of a random vector is a good estimate of the true covariance matrix if the sample size is much larger than the length of the vector. In high-dimensiona…
