AbstractA formação da convecção profunda na Amazônia ainda não está bem compreendida, existindo uma deficiência da sua representação nos processos físicos dos modelos numéricos de previsão de tempo e clima. Uma hipótese explorada foi: que os diferentes regimes de escoamento noturnos afetam as condições atmosféricas diurnas. Pois, a geração mecânica de turbulência pelo cisalhamento do vento durante a noite e a destruição térmica pela estabilidade, faz com que ocorram diferentes regimes de escoamento na Camada Limite Noturna (CLN). O objetivo deste trabalho foi investigar a importância da CLN na ocorrência ou não das nuvens convectivas durante o decorrer do dia na região central da Amazônia, através de um estudo observacional e de modelagem. Para a parte observacional foram usados os dados do experimento GOAmazon 2014/5, e para a parte de modelagem foi utilizado o modelo global BAM (Brazilian Global Atmospheric model). Os resultados mais importantes são: i) Os dados de vento de radiossondagens, de dados de Radar Dopler e experimentos de modelagem mostram que existe uma clara relação entre os valores de vento horizontal e de umidade no topo e acima da CLN com a formação ou não de nuvens convectivas profundas durante o decorrer do dia e ii) os experimentos de modelagem, mostram que os ventos fracos e altos valores de umidade acima da CLN (na Camada Residual), assim como a ocorrência de chuvas intensas na Amazônia Central, podem estar associados ao transporte vertical turbulento noturno e, também, a fatores de grandes escala. ABSTRACT: The formation of deep convection in the Amazon is not yet well understood. There is a deficiency of its representation in the physical processes of numerical models of weather and climate forecasting. It is hypothesized here that the different flow regimes at night affect the daytime atmospheric conditions, as the mechanical generation of turbulence by wind shear at night and thermal destruction by stability causes different flow regimes to occur in the Nocturnal Boundary Layer (NBL). The aim of this study was to investigate the importance of the NBL in the occurrence or not of deep convection during the day in the central region of the Amazon through an observational and modeling study. For the observational part, we used the GOAmazon 2014/5 experiment data, and for the modeling part, the CPTEC global model BAM (Brazilian Global Atmospheric Model). The most important results are listed here: i) radiosondes wind data, Doppler data, and modeling experiments, show that there is a clear relationship between horizontal wind intensity and humidity above NBL with the formation or not of deep convective clouds during the day and ii) modeling experiments show that weak winds and high humidity values above the NBL (in the residual layer), as well as the occurrence of heavy rainfall in the Central Amazon during the day, are associated with vertical turbulent mixing during the night as well as with large-scale factors.
