“…Geomagnetic pulsations were first observed in 1859 during aurora events (Stewart, 1861) Saito (1969) reviews geomagnetic pulsations and their classification, observations, and the generation mechanisms. This assessment remains a consistent work in the field and was followed by a number of updated reviews on more specific topics such as type of pulsation, frequency range of occurrence, and satellite observations, emphasizing geomagnetic pulsations relevance for a variety of Earth and space science studies (Raspopov and Lanzerotti, 1976;Pilipenko, 1990;Engebretson et al, 1991;Sazhin and Hayakawa, 1994;Takahashi, 1998;Kangas et al, 1998;Daglis et al, 1999;Olson, 1999;Yahnin and Yahnina, 2007;Zong et al, 2009 degrees north of Phimai. They argue that the nature and period of the geomagnetic pulsation was consistent with a dynamo action in the low ionosphere due to gravity waves triggered by the ocean floor displacement.…”

Investigation of coupling mechanisms between the troposphere and the ionosphere requires a multidisciplinary approach involving several branches of atmospheric sciences, from meteorology, atmospheric chemistry, and fulminology to aeronomy, plasma physics, and space weather. In this work, we review low frequency electromagnetic wave propagation in the Earthionosphere cavity from a troposphere-ionosphere coupling perspective. We discuss electromagnetic wave generation, propagation, and resonance phenomena, considering atmospheric, ionospheric and magnetospheric sources, from lightning and transient luminous events at low altitude to Alfven waves and particle precipitation related to solar and magnetospheric processes. We review in situ ionospheric processes as well as surface and space weather phenomena that drive troposphere-ionosphere dynamics. Effects of aerosols, water vapor distribution, thermodynamic parameters, and cloud charge separation and electrification processes on atmospheric electricity and electromagnetic waves are reviewed. We also briefly revisit ionospheric irregularities such as spread-F and explosive spread-F, sporadic-E, traveling ionospheric disturbances, Trimpi effect, and hiss and plasma turbulence. Regarding the role of the lower boundary of the cavity, we review transient surface phenomena, including seismic activity, earthquakes, volcanic processes and dust electrification. The role of surface and https://ntrs.nasa.gov/search.jsp?R=20120011991 2018-05-12T18:35:14+00:00Z atmospheric gravity waves in ionospheric dynamics is also briefly addressed. We summarize analytical and numerical tools and techniques to model low frequency electromagnetic wave propagation and solving inverse problems and summarize in a final section a few challenging subjects that are important for a better understanding of tropospheric-ionospheric coupling mechanisms.

“…The Miller force, the magnetic moment pumping, and other types of ponderomotive forces have become widely used in space physics since they allow us to simplify the dynamical equation and this leaves room for a qualitative study of the diversity of natural phenomena (e.g., Lundin and Hultqvist, 1989;Lundin, 1988;Erlandson et al, 1990Erlandson et al, , 1992Gustafsson et al, 1990;Lundin et al, 1990;Allan et al, 1991;Lundin and Eliasson, 1991;Allan, 1992Allan, , 1993aGuglielmi, 1992Feygin et al, 1997;Guglielmi et al, 1995Hultqvist, 1996;Kangas et al, 1998;Shukla and Rosenberg, 1999;Guglielmi and Lundin, 2001) In many interesting cases this is practically impossible on basis of the Lorentz force only (1).…”

This review is devoted to ponderomotive forces and their importance for the acceleration of charged particles by electromagnetic waves in space plasmas. Ponderomotive forces constitute timeaveraged nonlinear forces acting on a media in the presence of oscillating electromagnetic fields. Ponderomotive forces represent a useful analytical tool to describe plasma acceleration. Oscillating electromagnetic fields are also related with dissipative processes, such as heating of particles. Dissipative processes are, however, left outside these discussions. The focus will be entirely on the (conservative) ponderomotive forces acting in space plasmas. The review consists of seven sections. In Section 1, we explain the rational for using the auxiliary ponderomotive forces instead of the fundamental Lorentz force for the study of particle motions in oscillating fields. In Section 2, we present the Abraham, Miller, Lundin-Hultqvist and Barlow ponderomotive forces, and the Bolotovsky-Serov ponderomotive drift. The hydrodynamic, quasihydrodynamic, and "test-particle" approaches are used for the study of ponderomotive wave-particle interaction. The problems of self-consistency and regularization are discussed in Section 3. The model of static balance of forces (Section 4) exemplifies the interplay between thermal, gravitational and ponderomotive forces, but it also introduces a set of useful definitions, dimensionless parameters, etc. We analyze the Alfvén and ion cyclotron waves in static limit with emphasis on the specific distinction between traveling and standing waves. Particular attention has been given to the impact of traveling Alfvén waves on the steady state anabatic wind that blows over the polar regions (Section 5). We demonstrate the existence of a wave-induced cold anabatic wind. We also show that, at a critical point, the ponderomotive acceleration of the wind is a factor of 3 greater than the thermal acceleration. Section 6 demonstrates various manifestations of ponderomotive forces in the Earth's magnetosphere, for instance the ionospheric plasma acceleration and outflow. The polar wind and the auroral density cavities are considered in relation to results from the Freja and Viking satellites. The high-altitude energization and escape of ions is discussed. The ponderomotive anharmonicity of standing Alfvén waves is analyzed from ground based ULF wave measurements. The complexity of the many challenging problems related with plasma processes near the magnetospheric boundaries is discussed in the light of recent Cluster observations. At the end of Section 6, we consider the application of ponderomotive forces to the diversity of phenomena on the Sun, in the interstellar environment, on newborn stars, pulsars and active galaxies. We emphasize the role of forcing of magnetized plasmas in general and ponderomotive forcing in particular, presenting some simple conceivable scenarios for massive outflow and jets from astrophysical objects.
