| Abstract | An important research domain is referred to the forest-atmosphere interaction, since the flow in the region immediately above the vegetation is complex and has characteristics still not well known. One of these characteristics is the existence, in some situations, of relative maxima in the wind velocity vertical profiles, the low level jets (LLJ), in regions less than 1 km distant from the surface. They may contribute to intensify the mixture in the surface and in the region where they occur. It is possible that the presence of such phenomenon introduce additional difficulties in the parameterization of the forest-atmosphere exchange processes. Therefore, it is entirely reasonable the study of LLJs in order to determine the conditions of their occurrence and to investigate the consequences of their existence in the characteristics of the Nocturnal Boundary Layer (NBL) structure near the surface. The data were collected during the Field Experiment called CiMeLA (Mesoscale Circulations in the Eastern Amazonia), from October 27 to November 17 of 2003, in the Forest Reserve of Caxiuanã, Pará. During this Experiment, the measurements were vertical soundings of the atmosphere with radiosondes, launched at four different times per day (06, 12, 18, 00 UTC), except in the last three days of the Experiment, when there were soundings in every 3 hours (keeping the times above). BRAMS (Brazilian developments on the Regional Atmospheric Modeling System) was used to evaluate the origin of the LLJ. The numerical simulations presented contained 3 nested grids with a horizontal spacing of 45, 15 and 5 km. The models initialization was variable, each 6 hours, with the analysis of CPTECs global model, the radiosondes and surface data. The simulation used the models of surface and vegetation, radiation, cloud microphysics, deep convective parameterization of Grell and shallow convection parameterization. The numerical simulations with this high resolution model indicated the occurrence of low level jets, nevertheless it did not reproduce in detail some of the observed characteristics of the flow. It generated both LLJs of November 13 and 14 at 06 UTC. However, their magnitude was about 2 and 3 m/s lower and their height was higher than what was observed. Another interesting result was that the equivalent potential temperature indicated the arrival of thermodynamically different air possibly associated to the LLJ. An important aspect revealed by the simulations with BRAMS was the origin of the jets, which is associated to a phenomenon of canalization of the flow above zones where there are some of the great rivers in the Northeast of Pará. | |||
