Causes of the longitudinal differences in the equatorial vertical E × B drift during the 2013 SSW period as simulated by the TIME‐GCM
(American Geophysical Union, 2015-05-22)
During stratospheric sudden warming (SSW) periods large changes in the low‐latitude vertical drift have been observed at Jicamarca as well as in other longitudinal sectors. In general, a strengthening of the daytime maximum ...
Effect of a large-amplitude circularly polarized wave on linear beam-plasma electromagnetic instabilities
(Blackwell Publishing Ltd, 2003)
In a previous paper, sufficiently large-amplitude and left-handed ‘‘pump waves’’
propagating parallel to the background magnetic field were shown to stabilize a
moderately dense beam in a proton plasma against the ...
Drifting time of a standard drillship
(ASMESan Francisco, 2014-06-08)
This paper presents a methodology in order to perform a drift off calculation for drillships according to given parameters such as: environmental conditions and water depth. Drift off occurs when there is insufficient ...
Nonmodal energetics of resistive drift waves
(1998-09-01)
The modal and nonmodal linear properties of the Hasegawa-Wakatani system are examined. This linear model for plasma drift waves is nonnormal in the sense of not having a complete set of orthogonal eigenvectors. A consequence ...
Electrostatic instabilities triggered by finite amplitude Alfvén/ion-cyclotron waves and relative drifts among the ion components in the magnetosphere
(Blackwell Publishing Ltd, 2008)
Alfvén/ion-cyclotron waves have been observed in several regions of the magnetosphere. Parametric decays of finite amplitude Alfvén/ion- cyclotron waves in the presence of He+ ions and a mixed population of thermal and hot ...
Migração lateral da desembocadura do Rio Itapocú, SC, Brasil: evolução morfológica e condicionantes físicas
(Sociedade Brasileira de Geofísica, 2010)
Desembocaduras são ambientes bastante dinâmicos e sujeitos à complexa interação entre fatores estabilizadores e desestabilizadores. Dependendo dessa interação, desembocaduras podem apresentar a tendência de migração ao ...
Symmetry-induced pinning-depinning transition of a subharmonic wave pattern
(AMER PHYSICAL SOC, 2012-03-05)
The stationary to drifting transition of a subharmonicwave pattern is studied in the presence of inhomogeneities and drift forces as the pattern wavelength is comparable with the system size. We consider a pinning-depinning ...
A significant longshore transport divergence zone at the Northeastern Brazilian coast: implications on coastal Quaternary evolution
(Academia Brasileira de Ciências, 2002-09)
By using the mean directions of the wave-fronts approaching the Brazilian northeastern coastal stretch comprised between the localities of Real river (Sergipe State) and Galinhos (Rio Grande do Norte State) - coincident ...
