Quantile Regression, Variational Autoencoders, and Diffusion Models for Uncertainty Quantification: A Spatial Analysis of Sub-seasonal Wind Speed Prediction
Ganglin Tian, Anastase Alexandre Charantonis, Camille Le Coz +2
This study aims to improve the spatial representation of uncertainties when regressing surface wind speeds from large-scale atmospheric predictors for sub-seasonal forecasting. Sub…
Improving sub-seasonal wind-speed forecasts in Europe with a non-linear model
Ganglin Tian, Camille Le Coz, Anastase Alexandre Charantonis +3
Sub-seasonal wind speed forecasts provide valuable guidance for wind power system planning and operations, yet the forecast skills of surface winds decrease sharply after two weeks…
A barycenter-based approach for the multi-model ensembling of subseasonal forecasts
Camille Le Coz, Alexis Tantet, Rémi Flamary +1
Ensemble forecasts and their combination are examined from the perspective of probability spaces. Manipulating ensemble forecasts as discrete probability distributions, multi-model…
Ruelle-Pollicott Resonances of Stochastic Systems in Reduced State Space. Part I: Theory
Mickaël Chekroun, Alexis Tantet, Henk Anton Dijkstra +1
A theory of Ruelle-Pollicott (RP) resonances for stochastic differential systems is presented. These resonances are defined as the eigenvalues of the generator (Kolmogorov operator…
Ruelle-Pollicott Resonances of Stochastic Systems in Reduced State Space. Part III: Application to the Cane-Zebiak model of the El Ni{ñ}o-Southern Oscillation
Alexis Tantet, Mickaël Chekroun, J. David Neelin +1
The response of a low-frequency mode of climate variability, El Ni{ñ}o-Southern Oscillation, to stochastic forcing is studied in a high-dimensional model of intermediate complexity…
Resonances in a Chaotic Attractor Crisis of the Lorenz Flow
Alexis Tantet, Valerio Lucarini, Henk A. Dijkstra
Local bifurcations of stationary points and limit cycles have successfully been characterized in terms of the critical exponents of these solutions. Lyapunov exponents and their as…
