                         realiza{\c{c}}{\~a}o deste estudo, foram utilizados dados do 
                         sat{\'e}lite de {\'o}rbita equatorial TRMM para 
                         caracteriza{\c{c}}{\~a}o das tempestades noturnas entre 00 e 12 
                         UTC. Por meio do uso de dados de radiosondagens provenientes da 
                         rean{\'a}lise ERA5, foi verificada a exist{\^e}ncia da 
                         convec{\c{c}}{\~a}o elevada e tamb{\'e}m as 
                         caracter{\'{\i}}sticas termodin{\^a}micas dos eventos 
                         considerados. Al{\'e}m disso, foram constru{\'{\i}}dos 
                         compostos atmosf{\'e}ricos determinando os padr{\~o}es

                         Al{\'e}m disso, foi selecionado um caso ocorrido durante o 
                         projeto RELAMPAGO na Argentina para realizar o estudo e comparar 
                         com os compostos gerados. Foram identificados 781 casos de 
                         convec{\c{c}}{\~a}o noturna na RSAS, sendo 204 relacionados a 
                         convec{\c{c}}{\~a}o elevada e 577 n{\~a}o elevadas. Os

                         studies show that the occurrence of mesoscale convective systems 
                         in the Southeast Region of South America (RSAS) has a relatively 
                         high frequency, especially at night. The present study aimed to 
                         describe the synoptic, dynamic and thermodynamic characteristics 
                         of this type of convection, as well as to verify the existence of 
                         high convection, which is convection associated with an air parcel 
                         that originates over a stable layer at low levels. To carry out 
                         this study, data from the TRMM equatorial orbit satellite were 
                         used to characterize night storms between 00 and 12 UTC. Through 
                         the use of radiosonding data from the ERA5 reanalysis, the 
                         existence of high convection was verified, as well as the 
                         thermodynamic characteristics of the events considered. In 
                         addition, atmospheric composites were constructed determining the 
                         synoptic patterns associated with the occurrence of elevated 
                         convection, as well as their differences in relation to 
                         non-elevated convection. In addition, a case that occurred during 
                         the RELAMPAGO project in Argentina was selected to carry out the 
                         study and compare with the generated compounds. A total of 781 
                         cases of nocturnal convection were identified in the RSAS, with 
                         204 related to elevated convection and 577 non-elevated. The 
                         synoptic compounds show the advance of a cold air mass related to 
                         cases of high convection, which is responsible for the formation 
                         of the stable boundary layer close to the surface and causing high 
                         instability.",
