Teleconnection patterns and Rossby wave propagation associated to generalized frosts over southern South America
(Springer, 2007-11)
Based on previous observational studies of the mean atmospheric circulation leading to generalized frosts (GF) in central Southern South America, it is possible to establish a hypothesis that specific large scale patterns ...
Energetics of wave propagation leading to frost events in South America: extratropical latitudes
(Wiley VCH Verlag, 2017-08)
The dynamics of wave propagation and energy associated with frosts in extratropical versus tropical South American latitudes is studied. A double wave train propagates through the southern hemisphere following the polar ...
Propagacão das ondas de rossby nos invernos de máxima freqüência de ocorrência de geadas na pampa úmida
(Sociedade Brasileira de Meteorologia, 2009)
Neste trabalho estudou-se a influência dos padrões de onda extratropicais, que favorecem o desenvolvimento de eventos extremos frios no sudeste Sul-Americano, e em particular na região conhecida como Pampa Úmida. O aquecimento ...
Propagacão das ondas de rossby nos invernos de máxima freqüência de ocorrência de geadas na pampa úmidaRossby wave propagation during winters of maximum frequency of frost occurrence over the wet pampa
(Sociedade Brasileira de Meteorologia, 2009-03)
Neste trabalho estudou-se a influência dos padrões de onda extratropicais, que favorecem o desenvolvimento de eventos extremos frios no sudeste Sul-Americano, e em particular na região conhecida como Pampa Úmida. O aquecimento ...
MultiTaper Method-Singular Value Decomposition (MTM-SVD): variabilidad espacio-frecuencia de las fluctuaciones del nivel del mar en el Pacífico surorientalMultiTaper Method-Singular Value Decomposition (MTM-SVD): spatial-frequency variability of the sea level in the southeastern Pacific

Wave dynamics in high Rossby number regime and their implication to the superrotation problem of Venus and Titan
(European Geosciences UnionVienna, 2014)
The superrotation of Venus and Titan’s atmospheres requires a complex dynamical process that involves convergence
of momentum at the equatorial region in both bodies. It has been argued that the existence of specific
wave ...
Characteristics of Atmospheric Wave-Induced Laminae Observed by Ozonesondes at the Southern Tip of South America
(Journal of Geophysical Research: Atmospheres, 2019)
Characteristics of Atmospheric Wave-Induced Laminae Observed by Ozonesondes at the Southern Tip of South America
(Blackwell Publishing, 2018-10)
Fluctuations of ozone concentrations with dimensions of a few kilometers (i.e., ozone laminae) are frequently found in ozone-sounding profiles. We used ozonesonde measurements made at the southern tip of South America to ...
Quiet variability of equatorial E × B drifts during a sudden stratospheric warming event
(American Geophysical Union, 2009-03-03)
We present strong evidence that during the January 2008 minor sudden stratospheric warming (SSW) event, the equatorial vertical E × B drifts exhibit a unique and distinctive daytime pattern. We do not think one event causes ...
