There is sufficient quantitative correspondence between the GCM and the linear solution to justify decomposing the linear simulation into parts forced by different processes, although in some regions, such as over North America, the simulation is unsatisfactory. Other findings are that 1) the 300 mb extratropical response to tropical forcing reaches 50 gpm over Alaska (given our frictional parameterization), which is smaller than the response to local thermal forcing, 2) the responses to sensible heating and lower tropospheric thermal transients are strongly anticorrelated, and 3) the circulation in the vicinity of the Andes in the GCM is not attributable to direct mechanical forcing by the mountains. -from Authors
