Response of global evaporation to major climate modes in historical and future Coupled Model Intercomparison Project Phase 5 simulations

The Southern Ocean in the Coupled Model Intercomparison Project phase 5

The Southern Ocean is an important part of the global climate system, but its complex coupled nature makes both its present state and its response to projected future climate forcing difficult to model. Clear trends in wind, sea-ice extent and ocean properties emerged from multi-model intercomparison in the Coupled Model Intercomparison Project phase 3 (CMIP3). Here, we review recent analyses o...

Atmospheric Model Intercomparison Project: Monsoon Simulations

Global Chemistry simulations in the amma multimodel interComparison projeCt

The composition of the troposphere over West Africa is influenced by a range of emission sources, including those from anthropogenic activity (e.g., biofuel and fossil fuel consumption), biogenic activity (e.g., from soil), lightning activity, biomass burning activity related to agricultural practices, and stratosphere–troposphere exchange (STE; see, e.g., Sauvage et al. 2007b; Ancellet et al. ...

Winter warming and summer monsoon reduction after volcanic eruptions in Coupled Model Intercomparison Project 5 (CMIP5) simulations

Though previous studies have shown that state-of-the-art climate models are rather imperfect in their simulations of the climate response to large volcanic eruptions, the results depend on how the analyses were done. Observations show that all recent large tropical eruptions were followed bywinter warming in the first Northern Hemisphere (NH) winter after the eruption, with little such response...

Evaluation of the regional climate response in Australia to large-scale climate modes in the historical NARCliM simulations

Regional Climate Modelling (RCM) projects are designed to: improve the regional representation of climate obtained from Global Climate Models (GCM) and to provide addedvalue (Giorgi and Mearns 1991) at the regional scale to the climate change signal. Global models are run at coarse spatial resolutions and they do not properly represent regional/ local features such as: topography, coastlines an...
