Abstract

RODRIGUES, THIAGO R. et al. Hourly interaction between wind speed and energy fluxes in Brazilian Wetlands - Mato Grosso - Brazil. An. Acad. Bras. Ciênc. [online]. 2016, vol.88, n.4, pp.2195-2209.  Epub Dec 01, 2016. ISSN 0001-3765.  https://doi.org/10.1590/0001-3765201620150130.

Matter and energy flux dynamics of wetlands are important to understand environmental processes that govern biosphere-atmosphere interactions across ecosystems. This study presents analyses about hourly interaction between wind speed and energy fluxes in Brazilian Wetlands - Mato Grosso - Brazil. This study was conducted in Private Reserve of Natural Heritage (PRNH SESC, 16º39'50''S; 56º47'50''W) in Brazilian Wetland. According to Curado et al. (2012), the wet season occurs between the months of January and April, while the June to September time period is the dry season. Results presented same patterns in energies fluxes in all period studied. Wind speed and air temperature presented same patterns, while LE was relative humidity presented inverse patterns of the air temperature. LE was predominant in all seasons and the sum of LE and H was above 90% of net radiation. Analyses of linear regression presented positive interactions between wind speed and LE, and wind speed and H in all seasons, except in dry season of 2010. Confidence coefficient regression analyses present statistical significance in all wet and dry seasons, except dry season of 2010, suggest that LE and H had interaction with other micrometeorological variables.

Keywords : Energy balance; latent heat flux; linear regression; micrometeorology; Pantanal; sensible heat flux.
