European snow cover in the EURO-CORDEX regional climate model ensemble: model evaluationNARA Subscribed
The EURO-CORDEX initiative provides a comprehensive set of regional climate simulations for the present and future European climate. We assess how well snow cover, a crucial component of the climate system, is represented in this model ensemble. We consider output from 11 regional climate models (RCMs) at 12 km resolution, driven by ERA-Interim and 10 different general circulation models, and compare it with model- and remote-...
Estimating present temperature climate in a warming world: probabilistic verification of a model-based approach for years 2008–2025NARA Subscribed
When climate changes, statistics derived from past observations become unrepresentative of the true present climate. In 2008, Räisänen and Ruokolainen proposed a method for alleviating this bias, combining global mean temperature change with model-based regression coefficients that translate the global warming to changes in local mean temperature and temperature variability. Here, the fidelity of this method in predicting the...
This study evaluates changes in tropical cyclone (TC) characteristics under different future emissions scenarios in a large set of climate models from the Coupled Model Intercomparison Project Phase 6 (CMIP6). The Okubo–Weiss–Zeta parameter (OWZP) TC detection method is used to identify large-scale conditions conducive to TC formation. By comparing TC detections from CMIP6 historical simulations (1984–2014) with projections fo...
The role of global warming trend and tropical interannual variability as drivers of South America’s 2022–2024 climate extremesNARA Subscribed
From 2022 to 2024, South America experienced unprecedented regional climate extremes with severe socioeconomic impacts. These included extreme anomalies in temperature and precipitation, causing extreme drought conditions in southeastern South America and the Altiplano during spring 2022; extreme fire weather in central Chile in summer 2023; flooding in Rio Grande do Sul during autumn 2024; and the multiyear Amazon drought per...
Vietnam’s Mekong Delta plays a pivotal role in national and global food security. However, agriculture-based livelihoods in the delta are highly susceptible to climate extremes, highlighting the need for more localized climate change information. Hence, this study applied univariate and multivariate bias correction methods to raw climate model simulations from the Coupled Model Intercomparison Project Phase 6 under eight Share...
Atmospheric forcing and ocean preconditioning for dense shelf water cascading in the northwestern MediterraneanNARA Subscribed
Dense shelf water cascading (DSWC) in the northwestern Mediterranean Sea occurs due to the densification and overflow of shelf water in winter. This process ventilates the deep basin with waters that can be denser than those generated by open-ocean convection. Between 1987 and 2021 (i.e., 35 winter periods), shelf water reached depths greater than 1000 m on only 9 occasions, and open questions remain regarding the triggering f...
Modulation of Ural blocking and Eurasian winter climate by the quasi-biennial oscillationNARA Subscribed
Ural blocking is a major driver of Eurasian winter climate variability, but its modulation by equatorial stratospheric variability remains poorly understood. Using NCEP/NCAR reanalysis data from 1960 to 2023, we show that the quasi-biennial oscillation (QBO) significantly alters the structure, vertical extent, and persistence of Ural blocking via wave–mean flow interactions. During the westerly QBO (WQBO), Ural blocking anomal...
