This study presents an analysis of the vertical structure of the low level tropical atmosphere, north region of Brazil, using radiosonde data at Manaus. A dynamical model involving flow/Low Level Jet (LLJ) between the 950hPa and 926 hPa levels, between 860 hPa and 880 hPa levels (correspounding to 850 hPa intermediary level) and in the third higher layer between 800 hPa and 700 hPa levels (middle levels) is described. These streams and jets characterise a dynamical process of intense energy and mass transport, creating a turbulent stratified structure which is very efficient in producing convection at tropical region, demonstrating the influence of the Tropical Planetary Boundary Layer (TPLB), in the mesoscale convection generation.
