Extreme precipitation events are one of the most dangerous hydrometeorological disasters, often resulting in significant human and socio-economic losses worldwide. It is therefore important to use current global climate models project future changes extremes. The present study aims assess extremes over South Asia from Coupled Model Intercomparison Project Phase 6 (CMIP6) Global Climate Models (...

Based on the observational dataset CN05.1 and Coupled Model Intercomparison Project (CMIP), this study assesses performance of CMIP5 CMIP6 projects in projecting mean precipitation at annual seasonal timescales Yangtze River Basin China over period 2015–2020 under medium emission scenarios (RCP4.5/SSP2-4.5). Results indicate that multi-model ensemble (MME) overall has lower relative bias root-m...

27 28 Previous studies have demonstrated a link between gross moist stability (GMS) and intraseasonal 29 variability in theoretical and reduced-complexity models. In such simplified models, moisture modes— 30 convectively coupled tropical disturbances akin to the MJO whose formation and dynamics are linked to 31 moisture perturbations—develop only when GMS is either negative or " effectively " ...

This paper discusses some of the recent improvements in instrumentation used for stable isotope tracer measurements in the context of measuring retinol stores, in vivo. Tracer costs, together with concerns that larger tracer doses may perturb the parameter under study, demand that ever more sensitive mass spectrometric techniques are developed. GCMS is the most widely used technique. It has hig...

The IPCC Fourth Assessment Report (AR4) assessed a range of scenarios of future greenhouse gas emissions without policies to specifically reduce emissions, and concluded that these would lead to an increase in global mean temperatures of between 1.4°C and 6.9°C by the end of the 21st Century, relative to pre-industrial. While much political attention is focussed on the potential for global warm...

Global climate models (GCMs) from the sixth Coupled Model Intercomparison Project Phases (CMIP6) have been employed to simulate twenty-first-century temperatures for risk assessment of future change. However, their transient response (TCR) ranges 1.2 2.8 °C, whereas equilibrium sensitivity (ECS) 1.8 5.7 leading large variations in climatic impact an anthropogenic increase atmospheric CO2 levels...

Abstract Recently it has been suggested that natural variability in sea surface temperature (SST) patterns over the historical period causes a low bias estimates of climate sensitivity based on instrumental records, addition to by time variation feedback parameter atmospheric general circulation models (GCMs) coupled dynamic oceans. This excess, unforced, “pattern effect” (the effect evolving s...

Atmospheric circulation is a key driver of climate variability, and the representation atmospheric modes in regional models (RCMs) can enhance credibility projections. This study examines large-scale Coupled Model Inter-comparison Project phase 5 RCMs once driven by ERA-Interim, two general (GCMs). The region Western Europe are classified using Promax rotated T-mode principal component analysis...

Abstract The Canary current upwelling is one of the major eastern boundary coastal systems in world, bearing a high productive ecosystem and commercially important fisheries. system (CCUS) has large latitudinal extension, usually divided into zones with different characteristics. Eddies, filaments other mesoscale processes are known to have an impact productivity, thus for proper representation...
