Fluxo de metano na atmosfera sobre uma cultura de arroz irrigado por inundação no sul do Brasil
(Universidade Federal de Santa Maria, 2016-08-10)
The rice paddy is responsible for 12-16% of the anthropogenic emission of CH4 in the
world. Brazil is one of most important rice paddy producer. The goal of this study is to
understand the dynamics of methane exchange ...
Simulação numérica dos regimes da camada limite estável
(Universidade Federal de Santa Maria, 2019-11-11)
Recent studies have shown that the stable boundary layer (SBL) presents two distinct regimes.
In the weakly stable regime, turbulence is continous and similarity relationships are
valid, while in the very stable regime ...
Escalas temporais do escoamento noturno dentro e acima de um dossel na Amazônia
(Universidade Federal de Santa Maria, 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 ...
Não-estacionariedade de séries temporais turbulentas e a grande variabilidade dos fluxos nas baixas freqüências
(Universidade Federal de Santa Maria, 2011-08-11)
Turbulent flow high complexity makes it difficult to describe complex phenomena,
such as the transport of vector and scalar quantities at the lower atmosphere,
making the analysis of experimental data, such as time series, ...
Modelo simplificado para turbulência na camada limite noturna
(Universidade Federal de Santa Maria, 2016-03-08)
The appropriate estimation of turbulent fluxes in very stable conditions is a great challenge
for numerical models that simulate the average behavior of the stable boundary layer.
Although many features of the flow are ...
Usando a decomposição em modos empíricos para determinação de fluxos turbulentos entre oceano/atmosfera
(Universidade Federal de Santa Maria, 2015-04-08)
Turbulent fluxes may be directly determined as the statistical covariance between
quantities locally observed. Besides environmental and instrumental difficulties associated
with taking high frequency measurements over ...
