Precipitation extremes and their potential future changes were predicted using six - member
ensembles of general circulation models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5).
Seven global vegetation models are used to analyze possible responses to future climate simulated by a
range of general circulation models run under all four representative concentration pathway scenarios of changing concentrations of greenhouse gases.
However, another source of uncertainty in the monthly mean zonal cloud radiative effects comes from the low frequency of clear - sky occurrence, when averaging over regions that correspond to the spatial
resolution of general circulation models.
Using those scenarios, we employed standard modeling techniques available to climate scientists today —
ensembles of general circulation models — and projected Montana's climate over the next century.

of a General Circulation Model.
There is not even one single solution to
any of the general circulation models.
