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 ...
Implementação de um modelo de coluna simples para a camada limite estável utilizando diferentes formulações de turbulência
(Universidade Federal de Santa Maria, 2012-10-01)
In this work a single column model is implemented, aiming primarily to simulate the Stable
Boundary Layer (SBL). The model is composed of prognostic equations for the potential
temperature, specific humidity and the wind ...
Balanços de momentos estatísticos de segunda ordem na camada limite atmosférica diurna e noturna em função do vento
(Universidade Federal de Santa Maria, 2021-10-28)
The study presents an observational analysis of the terms in the budgets of three planetary
boundary-layer second-order statistical moments: turbulent kinetic energy (TKE), heat flux
and temperature variance. These have ...
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 ...
Parametrização de turbulência na previsibilidade de temperaturas mínimas em um modelo de mesoescala
(Universidade Federal de Santa Maria, 2014-06-02)
The present study aims to evaluate the quality of nocturnal temperature forecast
made by a mesoscale numerical model and to understand the reasons behind the difficulties
found. To do that, the Weather Research and ...
