Mode-coupling and nonlinear Landau damping effects in auroral Farley-Buneman turbulence [PDF]
, 1998 The fundamental problem of Farley-Buneman turbulence in the auroral $E$-region has been discussed and debated extensively in the past two decades. In the present paper we intend to clarify the different steps that the auroral $E$-region plasma has to ...

A Personal Voyage Among Earth and Space Physics Disciplines
Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract I have organized my thoughts in an autobiographical way in relation to the several distinct phases of my career encompassing Earth and space physics. I discuss atmospheric and space physics topics of interest to me in an international context, and I emphasize the value of community activities and international conferences for the interchange ...

Magnetosphere-Ionosphere Coupling Through E-region Turbulence 1: Energy Budget
, 2011 During periods of intense geomagnetic activity, strong electric fields and currents penetrate from the magnetosphere into high-latitude ionosphere where they dissipate energy, form electrojets, and excite plasma instabilities in the E-region ionosphere ...

Equatorial electrojet and Sq current system. I.
Journal of geomagnetism and geoelectricity, 1979 A new method based on covariance analysis is used to map the current patterns associated with variations of the equatorial electrojet. These patterns show that the electrojet is the expected equatorial enhancement of a coherent, large scale current system. This current system is further broken down and found to be composed of a part which is identified
