Daniele S. Nogueira, Leonardo D. A. Sá

Abstract


An investigation about the nocturnal boundary layer (NBL)vertical structure above Caxiuanã Forest is carried out using the availabledata on November, 10th, 2006, during COBRA-PARA Experiment. It isshown that during this day, a synergistic interaction of two typicalphenomena of the nocturnal atmosphere at Caxiuanã occurs: low leveljets (LLJ) and strong wind gusts. It is observed that the LLJ top-downmixing effect in the NBL sometimes reaches the surface, which occurssuccessively at characteristic time intervals, generating globalintermittency.
