             abstract = "A new version of ETA WS (workstation) forecast model destined for 
                         long-term climate change simulation (ETA CCS) was designed. 
                         Numerous modifications and corrections have been made in the 
                         original code of the ETA WS forecast model. As a first step in the 
                         ETA CCS validation program, we have integrated the model over 
                         South America with a horizontal resolution of 40 km for the period 
                         1960-1990. We forced it at its lateral boundaries by the outputs 
                         of HadAM3P, which provides a simulation of modern climate with a 
                         resolution of about 150 km. The climate ETA model was run on the 
                         supercomputer SX-6. Here, we present and compare the output fields 
                         of the ETA model and HadAM3P and analyze the geopotential, 
                         temperature, and wind fields of both models. For evaluating the 
                         similarities of the model outputs, we used a Fourier analysis of 
                         time series, the consistency index from linear regression 
                         coefficients, the time mean and space mean models' arithmetic 
                         difference and root mean square difference. The results of the 
                         study demonstrate that there are no significant differences in 
                         behavior and spatial arrangement of large-scale structures of the 
                         two models. In addition, the regional model characteristics do not 
                         have major positive or negative trends during the integration in 
                         relation to the global model. Our analysis shows that the 
                         descriptions of large-scale climate structures by these two models 
                         are consistent. This means that the ETA CCS model can be used for 
                         downscaling HadAM3P output fields. Our proposed technique can be 
                         used to evaluate the consistency of any regional model and its 
                         driving global model.",
