Kinetic simulations of 3‐D Farley‐Buneman turbulence and anomalous electron heating
(American Geophysical Union, 2013-02-27)
Electric fields map from the magnetosphere to the E region ionosphere where they drive the intense currents of the auroral electrojet. Particularly during geomagnetic storms and substorms, these currents become sufficiently ...
Polarization of elliptic E region plasma irregularities and implications for coherent radar backscatter from Farley‐Buneman waves
(American Geophysical Union, 2006-08-12)
The problem of two‐dimensional, homogeneous, elliptical irregularities in an otherwise homogeneous plasma with anisotropic conductivity is considered. We find an analytic solution for the potential inside and outside the ...
Unexpected rapid decrease in phase velocity of submeter Farley-Buneman waves with altitude
(American Geophysical Union, 2008-02-09)
An unexpected and drastic drop in the phase velocity Vph of Farley‐Buneman (FB) waves with increasing altitude was observed in the equatorial electrojet over Jicamarca. The effect was detected with the newly employed 430‐MHz ...
Energy exchange rate for the equatorial electrojet: Test of the model of two‐stream processes that includes thermal corrections
(American Geophysical Union, 2007-10-25)
The experiment of Balsley and Farley (1971) in Jicamarca, Peru has been the only multi(3)‐frequency investigation of the equatorial electrojet. The radar was operated sequentially at frequencies of 16.25, 49.92 and 146.25 ...
Radar scatter from equatorial electrojet waves: An explanation for the constancy of the Type I Doppler shift with zenith angle
(American Geophysical Union, 2008-02-26)
The first results from the 430 MHz Advanced Modular Incoherent Scatter Radar Prototype (AMISR‐P) at the Jicamarca Radio Observatory were reported by Hysell et al. (2007). We present additional data showing that the phase ...
Lessons learned observing Farley Buneman waves at low, middle, and high latitudes
(Instituto Geofísico del Perú, 2008)
Diapositivas presentadas en: ISEA 12 - 12th International Symposium on Equatorial Aeronomy, May 18-24, 2008. Crete, Greece.
Ion thermal effects on E-region instabilities: linear theory
(Elsevier, 2004-11)
Linear instabilities and turbulent processes in ionospheric electrojets lead to the formation of plasma density irregularities which create strong radar reflections. Studies of these irregularities have focused on the role ...
Combined radar observations of equatorial electrojet irregularities at Jicamarca
(European Geosciences Union (EGU), 2007-03-08)
Daytime equatorial electrojet plasma irregularities were investigated using five distinct radar diagnostics at Jicamarca including range-time-intensity (RTI) mapping, Faraday rotation, radar imaging, oblique scattering, ...
Simulações Particle-in-Cell da interação entre fótons e plasmas de lítio
(2015-11-11)
O presente trabalho consistiu na elaboração de um modelo de aceleradores de partículas super potentes que são capazes de atingir campos elétricos da ordem 1 GeV/m, ou seja, capazes de ultrapassar o limite de disrupção ...
Evidence for anomalous cowling conductivity in the strongly driven equatorial electrojet and a reconciliation of magnetic field data with theory
(2009-08)
Several days of continuous incoherent scatter radar observations during the November 2004 magnetic superstorm are available, as well as data from the CHAMP [CHAllenging Minisatellite Payload] satellite magnetic fiel d ...
