%X This study investigates the capabilities of two regional models (the ICTP RegCM3 and the climate version of the CPTEC Eta model / EtaClim) in simulating the summer quasi-stationary circulations over South America during two extreme cases: the 1997/1998 El Niño and 1998/1999 La Niña. The results showed that both the models are successful in simulating the interannual variability of summer quasi-stationary circulation over South America. Both the models simulated the intensification of subtropical jet stream during the El Niño event, which favoured the blocking of transient systems and increased the precipitation over south Brazil. The models simulated the increase (decrease) of precipitation over north (west) Amazonia during the La Niña (El Niño) event. The upper level circulation is in agreement with the simulated distribution of precipitation. In general, the results showed that both the models are capable of capturing the main changes of the summer climate over South America during these two extreme cases and consequently they have potential to predict climate anomalies.
