                         of upper tropospheric cut-off lows (CL) in the Southeast Pacific 
                         Ocean. The analysis was based on multiespectral GOES imagery for 
                         two case studies, between 7 and 15 August 1993 and 19 and 26 
                         October 1999. It was observed that in the initial stage the CL is 
                         clearly identified using water vapor imagery. The information 
                         contained in this imagery helps to infer characteristics of the 
                         cloudiness patterns associated to the occurrence of CL. The 
                         presence of a cold frontal system associated with a wave pattern 
                         (ciclogenesis/ridge) which extends to the upper levels and an area 
                         of cloudiness in the east sector of the frontal system were 
                         indicative of the CL formation. Moreover, the identification of 
                         jet stream in the water-vapor image (precursor of the 
                         intensification and displacements of the wave pattern) was 
                         important to define the CL formation. On the other hand the CL may 
                         be easily identified in its mature stage over land using infrared 
                         imagery.",
