Variabilidade sazonal e controle biofísico da evapotranspiração na vegetação do bioma Pampa
(Universidade Federal de Santa Maria, 2017-10-17)
Evapotranspiration (ET) is an important component that connects water and energy cycles in terrestrial ecosystems. Understanding how ET changes with environmental factors is critical to a better understanding of ecological ...
Determinação dos fluxos turbulentos de calor e momentum entre o oceano e a atmosfera na região sudoeste do oceano Atlântico
(Universidade Federal de Santa Maria, 2017-08-31)
The knowledge about the mass and energy fluxes between the atmosphere and the ocean at different
regions of the planet is of utmost importance for the improvement of the weather and climate
predictions. This is mainly ...
Estudo da turbulência atmosférica na floresta Amazônica - análise de dados micrometeorológicos e modelagem numérica
(Universidade Federal de Santa Maria, 2017-08-31)
In this work, a study of atmospheric turbulence at the Amazon forest is done through the analysis
of nocturnal turbulence data and numeric modeling using a single column model. Important
issues in micrometeorology are ...
Modelo estatístico de previsão de produtividade de soja e arroz para o Rio Grande do Sul
(Universidade Federal de Santa Maria, 2017-08-14)
In this PhD thesis, the usefulness of the insertion of climatic indicators in a statistical model
for predicting rice and soybean yield in Rio Grande do Sul is presented. Initially, yield
data of the two crops were ...
Estudo da concentração de vapor d’água na camada limite atmosférica sobre a região da confluência Brasil-Malvinas
(Universidade Federal de Santa Maria, 2017-03-27)
The atmosphere is the smallest contributor of the planet's water tanks providing only 0.001% of the water
total mass. However, it is of fundamental importance for playing a key role in the atmosphere's physical processes.
The ...
Comparação entre abordagem multi-física em mesoescala e determinística em alta resolução na simulação numérica de sistemas convectivos de mesoescala na Bacia do Prata
(Universidade Federal de Santa Maria, 2017-04-28)
This study has objectively-assessed the performance of numerical simulations of Mesoscale
Convective Systems (MCSs) in the La Plata Basin (LPB) comparing two distinct approaches:
deterministic simulations in the ...
Determinação do potencial de ocorrência de sistemas convectivos de mesoescala para a América do Sul
(Universidade Federal de Santa Maria, 2017-03-24)
This work presents a study aimed at improving the prediction of Mesoscale Convective
Systems (MCSs) in the South America subtropical region through the development of a
specific index for this type of meteorological ...
