RISData Assimilation with Gaussian Mixture Models Using the Dynamically Orthogonal Field Equations. Part II: Applications
Publisher: American Meteorological Society
Abstract: he properties and capabilities of the Gaussian Mixture Model?Dynamically Orthogonal filter (GMM-DO) are assessed and exemplified by applications to two dynamical systems: 1) the double well diffusion and 2) sudden expansion ...
Data Assimilation with Gaussian Mixture Models Using the Dynamically Orthogonal Field Equations. Part I: Theory and Scheme
Publisher: American Meteorological Society
Abstract: his work introduces and derives an efficient, data-driven assimilation scheme, focused on a time-dependent stochastic subspace that respects nonlinear dynamics and captures non-Gaussian statistics as it occurs. The motivation ...
