A shadowing-based inflation scheme for ensemble data assimilation
Thomas Bellsky, Lewis Mitchell
Artificial ensemble inflation is a common technique in ensemble data assimilation, whereby the ensemble covariance is periodically increased in order to prevent deviation of the en…
Mathematics and Climate Infographics: A Mechanism for Interdisciplinary Collaboration in the Classroom
Ivan Sudakov, Thomas Bellsky, Svetlana Usenyuk +1
Infographics are a form of data visualization combining data, information, and statistics. Over the last ten years, infographics have become a popular method for displaying concise…
Non-global parameter estimation using local ensemble Kalman filtering
Thomas Bellsky, Jesse Berwald, Lewis Mitchell
We study parameter estimation for non-global parameters in a low-dimensional chaotic model using the local ensemble transform Kalman filter (LETKF). By modifying existing technique…
Adiabatic stability under semi-strong interactions: The weakly damped regime
Thomas Bellsky, Arjen Doelman, Tasso J. Kaper +1
We rigorously derive multi-pulse interaction laws for the semi-strong interactions in a family of singularly-perturbed and weakly-damped reaction-diffusion systems in one space dim…
