             abstract = "The zonda is a warm and extremely dry wind that occurs east of the 
                         Andes Cordillera in the extratropical latitudes of South America. 
                         Its orographic origin is similar to the foehn that blows in 
                         Germany and Austria and the chinook that occurs east of the Rocky 
                         Mountains. Three typical zonda events of different categories ( 
                         surface and elevated) are described, through observational and Eta 
                         - Centro de Previsao de Tempo e Estudos Climaticos (CPTEC) model 
                         output. During the events the temperature rises sharply by 
                         10degrees-15degreesC and the dewpoint temperature drops by 
                         15degrees- 20degreesC in an interval of a few hours. The sustained 
                         wind strength at the surface increases to 30 kt, with gusts of 
                         more than 40 kt. The episodes generally start around midday and 
                         last for about 10 h. The Eta - CPTEC model was able to forecast 
                         several aspects of the three analyzed zonda cases, such as wind 
                         strength, temperature, and humidity changes, and their starting 
                         and ending times. Some relationships between the intensity of the 
                         windward static stability and the zonda occurrence were observed. 
                         The synoptic pressure configuration resulting from frontal 
                         passages associated with depressions that moved over 
                         lower-than-normal latitudes preceded the zonda occurrence. 
                         Sensitivity experiments showed that, if the Andes were lower, more 
                         frequent but less intense zonda episodes could be expected.",
