             abstract = "The Eta Regional Climate Model (Eta RCM) is used by the Center for 
                         Weather Forecasts and Climate Studies (CPTEC) of the Brazilian 
                         National Institute for Space Research to produce seasonal climate 
                         forecasts since 2002. The model has also produced downscaling of 
                         global climate models of CMIP5 to support impact and adaptation 
                         studies and National Communications. The model has gone through 
                         upgrades along these years, which include the modifications to a 
                         finite volume dynamics, the cut-cells applied to the step-mountain 
                         eta vertical coordinate, for multidecadal integrations, among 
                         other modifications. Likewise, the Brazilian Earth System Model 
                         (BESM) has been developed in parallel to the development of the 
                         Eta RCM. The BESM is based on INPEs global atmospheric model, it 
                         is coupled to the MOM5 ocean model, has produced multicentennial 
                         integrations, and contributed to the CMIP5 dataset. The objective 
                         of this work is to show the dynamical downscaling of the Eta RCM 
                         driven by the BESM global model at T062L28 resolution, over the 
                         Tibetan Plateau (TP) domain for the period between May and June 
                         2003. The run started on the 10th April 2003. The Eta model was 
                         setup with 40-km horizontal resolution and 38 layers, in a domain 
                         that covers most of Asia, between 60oE-130C and 5oN-50oN. Sea 
                         surface temperature was provided by the BESM and was updated daily 
                         during the regional integration, whereas the lateral boundaries 
                         were updated every 6 hours with the BESM atmospheric conditions. 
                         The Eta RCM driven by BESM underestimates precipitation was over 
                         most of the area, in particular over the Plateau and in the 
                         eastern Asia. The EtaBESM run underestimates the 2-m temperature 
                         in the western part of the Plateau but overestimates in the 
                         eastern part and in the eastern Asia. The Eta RCM run driven by 
                         Era-Interim reanalysis reduces the errors found in the Eta-BESM 
                         run. Test with higher horizontal resolution in order to improve 
                         the representation of the topography will be shown.",
