Análise das componentes da equação do balanço de radiação utilizando o modelo Sebal no sul do Brasil
(Universidade Federal de Santa Maria, 2019-07-19)
Recently, the use of geotechnologies allows the identification in real time of the changes
that occur in the terrestrial surface, resulting from the natural phenomena and several anthropic
processes. Many changes of this ...
Influência da turbulência intermitente na estimativa dos fluxos de CO2 noturnos
(Universidade Federal de Santa Maria, 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 ...
Estudo do balanço de energia em um cultivo de trigo no Sul do Brasil
(Universidade Federal de Santa Maria, 2013-08-06)
Neste estudo, o fluxo de calor sensível (H), fluxo de calor latente (Le), evapotranspiração (ET), foram investigados utilizando o método de covariância de vórtices durante o período de cultivo de trigo em 2011. A estimativa ...
Trocas turbulentas de escalares acima e no interior de uma floresta de araucária no sul do Brasil
(Universidade Federal de Santa Maria, 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 ...
Caracterização do comportamento da camada limite planetaria durante a passagem de tempestades severas na região de Santa Maria, RS
(Universidade Federal de Santa Maria, 2022-12-28)
Convective storms can significantly alter the evolution of the flow in the Planetary Boundary
Layer (PBL). In this study, thermodynamic, kinematic and turbulent quantities were calculated
in the PBL during the passage ...
Eventos de drenagem de ar na camada limite muito estável
(Universidade Federal de Santa Maria, 2022-12-23)
The very stable boundary layer occurs on nights with light wind and clear skies, which cause
strong radiative cooling on the surface, changing the structure and some characteristics of
the normal stable boundary layer. ...
Caracterização da transição de regimes de escoamento na camada limite noturna sobre diferentes superfícies
(Universidade Federal de Santa Maria, 2022-12-23)
In the present study, the proposal of Acevedo et al. (2021) was applied to a dataset of 63 sites
of the AmeriFlux network, installed in regions with 6 different surface classifications. From the
application of the ...
Simulação da evolução da Camada Limite Planetária Amazônica em eventos de convecção profunda utilizando o modelo WRF
(Universidade Federal de Santa Maria, 2023-02-17)
The convection in the Amazon basin and its impacts on the Planetary Boundary Layer
(PBL) are extremely complex, the present study made two simulations using the Weather
Research and Forecasting (WRF) model with different ...
Sensibilidade às parametrizações físicas do WRF nas previsões dos parâmetros atmosféricos em shetland do sul e deception
(Universidade Federal de Santa Maria, 2013-02-05)
The Weather Research and Forecasting model (WRF) was executed with high resolution and
three nested grids of 12 km, 3 km and 1 km in the South Shetland and particularly in
Deception Island s bay, during the period from ...
Simulação do microclima urbano de Santa Maria - RS através do software ENVI-met
(Universidade Federal de Santa Maria, 2023-02-06)
One of the most apparent human impacts on climate is the modification of the atmospheric environment by the construction of cities. The construction of each factory, road, building of scribes and house destroys microclimates ...
