                         distributions of the number of cloud-to-ground (CG) flashes, the 
                         percentage of positive CG flashes and the peak current of negative 
                         and positive CG flashes obtained in Brazil for the period from 
                         1999 to 2004, with the same distributions observed by similar 
                         networks for long time periods in other countries. From a 
                         correlation analysis, it was found that the mean monthly 
                         distributions of the number of CG flashes are very similar, even 
                         though the period of larger lightning activity along the year in 
                         Brazil, a tropical country, is longer than in the other temperate 
                         countries. The mean monthly distributions of the percentage and 
                         the peak current of positive CG flashes are also very similar, 
                         while the mean monthly distribution of the peak current of 
                         negative CG flashes in Brazil differs from the other countries. 
                         This difference is related to a significant decrease in the mean 
                         negative peak current in Brazil in the months of August and 
                         September. Apparently, the decrease is related to the injection in 
                         the atmosphere of large amounts of smoke from fires in these 
                         months, since the results also show a significant correlation 
                         between the monthly distribution of the number of fires and the 
                         negative peak current.",
