Aplicação da análise de multiresolução no estudo da estrutura da turbulência sobre a Floresta Amazônica.

In this study, sonic anemometry measurements at 16 vertical levels of the ATTO tower were used to evaluate the temporal variation of the multiresolution (co)spectra of the wind speed and temperature components. This methodology made it possible to visualize, over a large vertical extent, which scales of turbulent movement contribute most to turbulent kinetic energy and turbulent transport of a quantity over the Amazon rainforest. In this respect, it was also possible to identify the turbulent scales most effective in the entrainment process in the early morning. The multiresolution analysis also highlighted the need to determine the scale of the spectral gap in order to obtain more robust estimates of turbulent fluxes, even for the daytime period.
