Tropical Upper Tropospheric Warming: Models vs. Measurements
Po-Chedley, S. and Fu, Q. 2012. Discrepancies in tropical upper tropospheric warming between atmospheric circulation models and satellites. Environmental Research Letters 7: 10.1088/1748-9326/7/4/044018.
The two researchers say their work demonstrated that "even with historical SSTs as a boundary condition, most atmospheric models exhibit excessive tropical upper tropospheric warming relative to the lower-middle troposphere as compared with satellite-borne microwave sounding unit measurements." In addition, they say that "the results from CMIP5 coupled atmosphere-ocean GCMs are similar to findings from CMIP3 coupled GCMs."
Thus, once again, climate model results are shown to deviate significantly from real-world measurements; and there appears to be no improvement in this regard between the CMIP3 set of models and the newer and supposedly improved CMIP5 models.
