For regional assessments of the effects of possible global climate change due to increasing greenhouse gases, two of the most significant variables predicted by general circulation models (GCMs) are surface air temperature and precipitation. In an earlier Department of Energy report, the results from four GCMs and several historical climate data sets for each of these variables (both seasonally and annually averaged) were intercompared over different regional scales using a variety of techniques. In the work reported here, several more recent, higher resolution simulations are included and attention is focused primarily on the southeastern United States. Two graphical/statistical techniques are applied: cuts intercomparing model/historical data predictions at both fixed latitudes and longitudes and side-by-side boxplots showing the quartiles of the distributions for a particular variable for a selected subset of gridpoints in a specified region. 4 refs., 11 figs.
