About the Role of Turbulence in an Intercropping System
(Sciencesdomain International, 2018-07)
Aims: It was analysed the role of turbulence in the interaction between the atmosphere and two types of cropping systems, a corn-soy intercrop and soybean monocrop. Study Design: Experimental. Place and Duration of Study: ...
Trocas turbulentas de escalares acima e no interior de uma floresta de araucária no sul do Brasil
(Universidade Federal de Santa MariaBRMeteorologiaUFSMPrograma de Pós-Graduação em Meteorologia, 2011-07-12)
Turbulent exchange of scalars is analyzed for a year of turbulence data, above and within an Araucaria Forest in southern Brazil. Sensible and latent heat fluxes, as well as CO2 fluxes are calculated by the eddy covariance ...
Aerosol properties, in-canopy gradients, turbulent fluxes and VOC concentrations at a pristine forest site in Amazonia
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Aerosol physical and chemical properties were measured in a forest site in central Amazonia (Cuieiras reservation, 2.61S; 60.21W) during the dry season of 2004 (Aug-Oct). Aerosol light scattering and absorption, mass ...
Modeling study of the aspect ratio influence on urban canopy energy fluxes with a modified wall-canyon energy budget scheme
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The influence of the aspect ratio (building height/street canyon width) and the mean building height of cities on local energy fluxes and temperatures is studied by means of an Urban Canopy Model (UCM) coupled with a ...
Escalas temporais do escoamento noturno dentro e acima de um dossel na Amazônia
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2015-07-17)
This work uses data from the three components of wind and temperature, collected in
an experimental site in the Amazon rainforest for 10 months during GOAmazon Project. A
total of 10 levels of sensors were deployed on a ...
Fog deposition to a Tillandsia carpet in the Atacama Desert
(COPERNICUS GESELLSCHAFT MBH, 2009)
In the Atacama Desert, one of the driest places on earth, fog deposition plays an important role for the water balance and for the survival of vulnerable ecosystems. The eddy covariance method, previously applied for the ...
Influência da turbulência intermitente na estimativa dos fluxos de CO2 noturnos
(Universidade Federal de Santa MariaBRMeteorologiaUFSMPrograma de Pós-Graduação em Meteorologia, 2012-09-05)
Nocturnal turbulent flux data are analysed, initially for two experimental sites in Brazil, and later for a large variety of biomes. In such case, a wide dataset, originated from more than a hundred flux stations scattered ...
Coherent structures detection within a dense alpine forest
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2022-09-29)
Foi investigada a influência dos vórtices coerentes na estrutura da turbulência e no fluxo de
momento dentro de uma floresta de coníferas em um planalto alpino na Itália. A presença das
estruturas coerentes e suas escalas ...
