The relative role of the subsurface Southern Ocean in driving negative Antarctic Sea ice extent anomalies in 2016–2021
Liping Zhang,Thomas L. Delworth,Xiaosong Yang,Fanrong Zeng,Feiyu Lu,Yushi Morioka,Mitchell Bushuk +6 more
TL;DR: In this paper , the authors investigate the causes of this period of low Antarctic sea ice extent using a coupled climate model partially constrained by observations, and find that the subsurface Southern Ocean played a smaller role than the atmosphere in the extreme Sea ice extent low in 2016, but was critical for the persistence of negative anomalies over 2016-2021.

Seasonal-to-decadal variability and prediction of the Kuroshio Extension in the GFDL Coupled Ensemble Reanalysis and Forecasting system
Youngji Joh,Thomas L. Delworth,Andrew T. Wittenberg,William Cooke,Xiaosong Yang,Fanrong Zeng,Liwei Jia,Feiyu Lu,Nathaniel C. Johnson,Sarah B. Kapnick,Anthony Rosati,Liping Zhang,Colleen McHugh +12 more
TL;DR: In this article , the authors explore the representation and prediction skill for the Kuroshio Extension (KE) in the GFDL SPEAR (Seamless System for Prediction and EArth System Research) coupled model.
An Empirical Benchmark for Decadal Forecasts of Global Surface Temperature Anomalies
TL;DR: The suitability of a linear inverse model (LIM) as a benchmark for decadal surface temperature forecast skill is demonstrated in this article, based on the observed simultaneous and 1-yr lag covariability statistics of annually averaged sea surface temperature (SST) and surface (2 m) land temperature global anomalies during 1901-2009.

A weakened AMOC may prolong greenhouse gas–induced Mediterranean drying even with significant and rapid climate change mitigation
TL;DR: In this article , the authors used climate model ensembles to explore whether Mediterranean rainfall declines could be reversed in response to greenhouse gas reductions, and found that the Mediterranean is a projected hot spot for climate change, with significant warming and rainfall reductions.

The Euro-Mediterranean Center on Climate Change (CMCC) decadal prediction system
Dario Nicolì,Alessio Bellucci,Paolo Ruggieri,Panos Athanasiadis,Stefano Materia,Daniele Peano,Giusy Fedele,Riccardo Hénin,Silvio Gualdi +8 more
TL;DR: In this article , the authors present results from the CMIP6 (Coupled Model Intercomparison Project Phase 6) Decadal Climate Prediction Project (DCPP) decadal hindcasts produced with the operational CMCC (Euro-Mediterranean Center on Climate Change) DECA decadal prediction system (DPS), based on the fully coupled CMCC-CM2-SR5 dynamical model.

Woollen,Yuejian Zhu,Muthuvel Chelliah,Wesley Ebisuzaki,Wayne Higgins,John E. Janowiak,Kingtse C. Mo,Chester F. Ropelewski,Julian X. L. Wang,Ants Leetmaa,Richard W. Reynolds,Roy L. Jenne,Dennis Joseph +21 more
TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.

An Overview of CMIP5 and the Experiment Design
TL;DR: The fifth phase of the Coupled Model Intercomparison Project (CMIP5) will produce a state-of-the- art multimodel dataset designed to advance the authors' knowledge of climate variability and climate change.
Journal ArticleDOI
A Pacific interdecadal climate oscillation with impacts on salmon production
TL;DR: In this article, the authors identify a robust, recurring pattern of ocean-atmosphere climate variability centered over the midlatitude North Pacific basin over the past century, the amplitude of this climate pattern has varied irregularly at interannual-to-interdecadal timescales.
