Equilibrium simulations using the best-available general circulation models to estimate the sensitivity of the climate to a doubling of the atmospheric carbon dioxide concentration are in broad. Abstract The problem of using data outputs from general circulation models (GCMs) to assess the impacts of climate change on runoff in West Africa is addressed. The annual and monthly precipitation data from four GCMs used in the Third Assessment Report .

A general circulation model (GCM) is a type of climate employs a mathematical model of the general circulation of a planetary atmosphere or ocean. It uses the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources (radiation, latent heat).These equations are the basis for computer programs used to simulate the Earth's atmosphere or oceans. B.W. Sellwood, P.J. Valdes, in Encyclopedia of Geology, Palaeoclimate Models. A recent approach to understanding past climate regimes on Earth has been through the application of complex computer models, specifically atmospheric general circulation models (AGCMs), ocean general circulation models (OGCMs), and recently even more complex coupled ocean–atmosphere general circulation.   General Circulation Models. General Circulation Models (GCMs) of the atmosphere were first developed in the late s and early s to study the interaction between the atmosphere and the environment and improve weather forecasting. Although the initial modeling centers were in the US, the GCM community now includes large modeling.   In addition, we need new approaches to predict the impacts of climate change at the community level (i.e. Mokany & Ferrier ). Currently, neither the estimates of species losses nor of the qualitative impacts on ecosystem functioning and services are satisfactory to give a global overview of the impacts of climate change (Dale et al. ).

In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and ocean acidification, with potentially wide-ranging biological effects. Population-level shifts are occurring because of physiological intolerance to new environments, altered dispersal patterns, and changes in. The impact of climatic extremes in the context of climatic change in Lake output from general circulation models (GCMs) of the climate system. and predict impacts of climate change.

Climate Dynam 45 - the impacts of climate change on agriculture and biodiversity is. Several researchers (particularly climatic researchers) state that original GCM (General Circulation Model) resolution should be kept in order to manage, understand and not bias or alter uncertainties produced by GCMs themselves; however, a coarse resolution of or.
