                         em cerca de 4 de latitude. Nas composi{\c{c}}{\~o}es dos casos

                         have documented the presence of double band (DB) of the 
                         Intertropical Convergence Zone (ITCZ) in the Pacific Ocean, while 
                         in the Atlantic Ocean, even though this phenomenon is known, there 
                         is practically no literature. Therefore, the purposes of this 
                         study are: to identify the occurrence of DB in the tropical 
                         Atlantic Ocean in the summer and autumn seasons, from 2010 to 
                         2017; to perform a composition analysis to different atmospheric 
                         variables considering events with DB and events without DB in 
                         order to showing the difference between them and to evaluate a 
                         hypothesis that tries to explain the formation process of DB in 
                         the Atlantic Ocean. To identify the DB cases, the synoptic surface 
                         charts prepared by the Weather Prediction Group (GPT) of the 
                         Center for Weather Forecasting and Climate Studies of the National 
                         Institute of Space Research (CPTEC/INPE), satellite images and the 
                         European Centre for Medium- -Range Weather Forecasts (ECMWF) 
                         Re-Analysis (ERA-Interim) reanalysis were used. The results show 
                         that the DBs are more frequent and lasting in March and April and 
                         that the two bands are distant from each other in ~ 4 of 
                         latitude. In the DB composite, the variables 10-m mass convergence 
                         and outgoing longwave radiation represent better the DB than the 
                         other variables. In the comparison of the composites for events 
                         with and without DB of the quoted variables, there are 
                         statistically significant negative anomalies southward equator. 
                         The hypothesis tested to explain the formation of DB in the 
                         Tropical Atlantic Ocean was partially proven.",
