TL;DR: The authors presented the global climate model IPSL-CM6A-LR developed at the Institut Pierre-Simon Laplace (IPSL) to study natural climate variability and climate response to natural and anthropogenic forcings as part of the sixth phase of the Coupled Model Intercomparison Project (CMIP6).

TL;DR: In this paper, the authors investigated the ocean-atmosphere coupling in the North Atlantic using maximum covariance analysis of sea surface temperature (SST) and 500-hPa geopotential height analyses and performing regressions on dynamical diagnostics such as Eady growth rate, wave activity flux, and velocity potential.

TL;DR: It is shown that an El Niño tends to peak during the year following large eruptions in simulations of the Fifth Coupled Model Intercomparison Project (CMIP5), and that a Pinatubo-like eruption cools tropical Africa and drives westerly wind anomalies in the Pacific favouring anEl Niño response.

TL;DR: In this paper, the authors performed coordinated experiments with six atmospheric general circulation models (AGCMs) forced by the observed and climatological daily sea-ice concentration and sea surface temperature (SST), and found that the impact of the recent sea ice decline is rather limited to the high-latitude lower troposphere in winter, and the seaice changes do not significantly lead to colder winters over Siberia.

TL;DR: In this article, the authors explored the changes in the frequency of occurrence of extreme wind storm events in response to anthropogenic global warming using a multi-model ensemble of coupled climate model simulations.
