A software was developed in the framework of the GEOWOW project for computing the mean of the output of an ensemble of climate change models from the World Climate Research Programme (WCRP) Coupled Model Intercomparaison Project Phase 5 (CMIP5). The ensemble mean for the time projections of the Sea Surface Temperature (SST) under climate change and the corresponding climatology were computed: t...

Abstract Investigation of the role multiple general circulation model (GCM) ensembles in obtaining comprehensive knowledge hydrological responses across Yellow River Basin (YRB), China, is still substantial importance. This study evaluates performance Coupled Model Intercomparison Project Phase 6 (CMIP6) models simulating regime YRB and compares results with those from CMIP 5 (CMIP5). The compa...

Abstract. Future wintertime atmospheric circulation changes in the Euro–Atlantic (EAT) and Pacific–North American (PAC) sectors are studied from a weather regimes perspective. The Coupled Model Intercomparison Project phases 5 6 (CMIP5 CMIP6) historical simulation performance reproducing observed is first evaluated, showing general improvement CMIP6 models, which more evident for EAT. projected...

Using observations and model simulations from the 5th 6th phases of Coupled Model Intercomparison Project (CMIP5 CMIP6, respectively), this study evaluated changes in monthly, seasonal, annual precipitation over Bolivia 1950 to 2019. Results demonstrate that observed is characterized by strong interannual decadal variability. However, long-term trends were not identified on scale. Similarly, se...

The impact of the increase of greenhouse gases on Sahelian precipitation is very uncertain in both its spatial pattern and magnitude. In particular, the relative importance of internal variability versus external forcings depends on the time horizon considered in the climate projection. In this study we address the respective roles of the internal climate variability versus external forcings on...

Regional surface temperature trends from the CMIP3 and CMIP5 20 th century runs are compared with observations -at spatial scales ranging from global averages to individual grid points -using simulated intrinsic climate variability from pre-industrial control runs to assess whether observed trends are detectable and/or consistent with the models’ historical run trends. The CMIP5 models are also...
