Abstract

This micrometeorologicall project, with the help of the University Federal de Mato Grosso do Sul (UFMS), is the initial part of a broad experimental program to study the characteristics of the weather and the climate of the central region of Brazil. Thus, a first data collection campaign during the flood season, in the South Mato Grosso Pantanal, is proposed to be arried out in a experimental site in the Fazenda São Bento (19°33’48, 2”S; 57°00’53, 8”W), a site representative of the region, located ca. 1.5 km from the Pantanal Studies Base of UFMS, in Passo do Lontra, Miranda, MS. A micrometeorologicall tower, 21 m high, is already installed, and it will serve as support both for fast response sensors to measure turbulence and for conventional meteorologicall instrumentation to measure vertical wind velocity, temperature and specific humidity profiles, as well as to obtain the radiation balance. Air samples will be collected to evaluate the surface emission of methane in the region. So, the seasonal structure of the surface boundary layer above the Pantanal will be investigated. Also, the influence in the change of the structure of the boundary layer due to meteorologicall phenomena of larger spatial scales, such as the incidence of cold fronts, the intensification of the South American Convergence Zone and the atmospheric instabilities will be studied. Furthermore, to better understand and parameterize the characteristics of the turbulent processes above the Pantanal, theoretical studies using modern signal analysis techniques, such as the wavelet transform, will be carried out. And special emphasis will be given to the error introduced by the sampling conditions, and by the surface roughness, for determination of the vertical fluxes of momentum, sensible heat and moisture. Part of the research activities proposed will result in scientific initiation works, master dissertations and doctoral theses, while all the results will be disseminated through the scientific literature.
