                         Research (NCEP/NCAR). Foram identificados 886 VCAN, sendo que 
                         75,3% perduraram de 2 a 4 dias. O n{\'u}mero de VCAN diminuiu

                         houve registro de ocorr{\^e}ncia de VCAN que perduram mais do que

                         intraseasonal and interannual variability of the number and life 
                         period of upper-tropospheric cyclonic vortex (UTCV) in South 
                         Tropical region to the period from 1979 to 2006. The 
                         identification of systems was obtained using the objective method 
                         developed by Coutinho et al (2010), which has as input data of 
                         reanalysis of National Centers for Environmental Prediction 
                         National Center for Atmosphere Research (NCEP/NCAR). 886 UTCV were 
                         identified with 75,3% that lasted from two to four days. The 
                         number of UTCV decreased as the it live period increased. In 
                         average in the summer was found the largest number of UTCV and the 
                         lowest number in the winter. The annual average occurrence of UTCV 
                         in the spring and fall was 6,3 and 6,5 respectively, while during 
                         the summer formed 18 UTCV by year and during the winter 0,8 cases. 
                         There was not register of occurrence of UTCV that lasted more than 
                         eight days during the winter.",
