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 ...
Estudos da camada limite atmosférica com o modelo WRF: fenologia de florestas temperadas, turbulência e relevo
(Universidade Federal de Santa Maria, 2018-09-27)
In this work, we have studied the behavior of surface variables and the Atmospheric Boundary
Layer (CLA) during the leaf emergence (EF) at the temperate forests of the northeast
United States of America. We have used the ...
Características da camada limite atmosférica marinha em cruzeiros oceanográficos realizados no Atlântico Sul e Equatorial
(Universidade Federal de Santa Maria, 2019-09-11)
A study of sensible (H) and latent (Le) heat fluxes between the ocean and the atmosphere,
using measurements performed by micrometeorological towers aboard Brazilian research
vessels in the South and Equatorial Atlantic ...
Análise da ocorrência do granizo através das simulações no modelo WRF sobre o Rio Grande do Sul
(Universidade Federal de Santa Maria, 2019-09-30)
Hail is a form of precipitation that occurs from falling irregular pieces of ice. It is a short-term
weather phenomenon that can occur in a small area in isolated events. Thus, as it is an
event that varies locally and ...
Relação entre demanda de energia elétrica e temperatura para concessionárias do Rio Grande do Sul
(Universidade Federal de Santa Maria, 2019-09-06)
This thesis aims to describe the correlation between the different characteristic air temperatures
in the state of Rio Grande do Sul and the demand for electrical energy (DEE)
registered for three regions (A, B and C)2 ...
Análise da estrutura vertical do escoamento atmosférico durante ocorrência de eventos turbulentos intermitentes na camada limite noturna
(Universidade Federal de Santa Maria, 2015-08-31)
The objective of this study is to analyze the vertical structure of the intermittent
turbulent events in the very stable boundary layer, as well the analysis and characterization
of events originated near the surface ...
Extremos de umidade na América do Sul e a contribuição do Oceano Atlântico Sul
(Universidade Federal de Santa Maria, 2016-03-03)
Extreme climatic events have been occurring with greater intensity and/or frequency over South America. Indicatives for these alterations encompass natural climate variability, land use (deforestation and urbanization), ...
Estimativa da probabilidade de ocorrência da precipitação, a partir de métodos estatísticos não paramétricos aplicados a simulações numéricas de um sistema de previsão por conjunto
(Universidade Federal de Santa Maria, 2016-07-15)
In this paper was used kernel density estimation (KDE), a nonparametric method to estimate
the probability density function of a random variable, to obtain probabilistic precipitation
forecasts from an ensemble prediction ...
Estimativa da partição de energia na superfície a partir de séries meteorológicas de temperatura e umidade específica do ar
(Universidade Federal de Santa Maria, 2015-07-03)
The developed method is proposed with the aim of estimating the energy partition on the
surface, according to the Bowen ratio method, and the height of convective boundary layer
on the monthly scale. The basic hypothesis ...
