TL;DR: The Stratosphere-troposphere Processes And their Role in Climate (SPARC) Quasi-Biennial Oscillation initiative (QBOi) aims to improve the fidelity of tropical stratospheric variability in general circulation and Earth system models by conducting coordinated numerical experiments and analysis as discussed by the authors.
Journal ArticleDOI
Towards Reliable Extreme Weather and Climate Event Attribution
Omar Bellprat,Omar Bellprat,Virginie Guemas,Francisco J. Doblas-Reyes,Markus G. Donat,Markus G. Donat +5 more
TL;DR: It is shown, exploiting advanced correction techniques from the weather forecasting field, that correcting properly for model probabilities alters the attributable risk of extreme events to climate change.
Journal ArticleDOI
Impact of land-surface initialization on sub-seasonal to seasonal forecasts over Europe
TL;DR: In this paper, the authors estimate how the initialization of the land surface affects the predictability at seasonal time scale, and run two sets of seasonal hindcasts with the general circulation model EC-Earth2.3.
Journal ArticleDOI

TL;DR: Large-scale diagnostics of the second major release of the ESMValTool tool, a community diagnostics and performance metrics tool designed to improve comprehensive and routine evaluation of Earth system models participating in the Coupled Model Intercomparison Project (CMIP), are described.
Journal ArticleDOI
Objective calibration of regional climate models
TL;DR: In this paper, an approach to objectively calibrate a regional climate model, using reanalysis driven simulations and building upon a quadratic metamodel presented by Neelin et al. (2010), is presented.
