| Abstract | Foram usados neste estudo dados de resposta rápida coletados em torre micrometeorológica de 21 metros de altura no Pantanal Matogrossense, amostrados a uma freqüência de 20.8 Hz na estação alagada e de 16 Hz na estação seca. Os dados foram submetidos aos testes de qualidade propostos por Vickers e Mahrt (1997), através dos quais foi possível identificar e eliminar da análise as situações em que os sinais apresentaram problemas. Características da estrutura da Camada Limite Superficial (CLS) foram determinadas pelo cálculo de grandezas estatísticas da turbulência tais como fluxos de calor sensível e de momentum. Os fluxos foram calculados pelo método das covariâncias. Foram comparadas as evoluções diurnas desses parâmetros entre as duas estações, seca e alagada, e procurou-se explicar as diferenças encontradas com base em termos das equações prognosticas para fluxos turbulentos e no coeficiente de assimetria (skewness) da temperatura. Observou-se que o período do início da noite é um daqueles em que ocorrem as maiores diferenças entre a estrutura da CLS da estação seca e a da estação alagada. ABSTRACT: Fast response data, collected at a 21 m height micrometeorological tower at sampling rate of 20.8 Hz during the wet season, and of 16 Hz during the dry season, in Pantanal Wetland, were used in this study. The data were submitted to the quality control tests proposed by Vickers and Mahrt (1997), so it was possible to identify and eliminate from the analysis the situation in witch the signals presented problems. Surface Boundary Layer (SBL) structure characteristics were determined by turbulence statistical variables calculations as sensible heat and momentum fluxes. The fluxes were calculated using the covariance method. It was compared the diurnal evolution of these parameters between the two seasons, dry and flooded, and the differences that were found was explained based on terms of prognostic equations for turbulent fluxes and on temperature skewness. It was observed that the initial period of the night is one of the periods in witch the greatest differences between dry and flooded season SBL structure occurs. |
