Abstract. Dawn–dusk asymmetries are ubiquitous features of the coupled solar-wind–magnetosphere–ionosphere system. During the last decades, increasing availability of satellite and ground-based measurements has made it possible to study these phenomena in more detail. Numerous publications have documented the existence of persistent asymmetries in processes, properties and topology of plasma structures in various regions of geospace. In this paper, we present a review of our present knowledge…

Dawn-Dusk Asymmetries at the Terrestrial Magnetopause

The terrestrial magnetopause is a thin current sheet forming the boundary between the solar wind and the Earth’s magnetosphere. It is thus a key region for the transfer of energy and momentum from

Asymmetries in the Earth's dayside magnetosheath: results from global hybrid-Vlasov simulations

Abstract. Bounded by the bow shock and the magnetopause, the magnetosheath formsthe interface between solar wind and magnetospheric plasmas andregulates solar wind–magnetosphere coupling. Previous

Characteristics of the flank magnetopause: Cluster observations

The magnetopause is a current sheet forming the boundary between the geomagnetic field on one side and the shocked solar wind on the other side. This paper discusses properties of the low‐latitude

Interhemispheric differences in ionospheric convection: Cluster EDI observations revisited

The interaction between the interplanetary magnetic field and the geomagnetic field sets up a large‐scale circulation in the magnetosphere. This circulation is also reflected in the magnetically

Study on the local time asymmetry of the Earth’s ring currents based on multiple low-Earth-orbit satellite magnetic observations

The azimuthal morphology of Earth’s ring currents has consistently shown asymmetry during extreme space weather events at low latitudes, particularly during geomagnetic storms. A dawn-dusk pattern

Dusk‐Dawn Asymmetries in SuperDARN Convection Maps

The Super Dual Auroral Radar Network (SuperDARN) is a collection of radars built to study ionospheric convection. We use a 7‐year archive of SuperDARN convection maps, processed in 3 different ways,

Inter-hemispheric asymmetries in high-latitude electrodynamic forcing and the thermosphere during the October 8–9, 2012, geomagnetic storm: An integrated data–Model investigation

Inter-hemispheric asymmetry (IHA) in Earth’s ionosphere–thermosphere (IT) system can be associated with high-latitude forcing that intensifies during storm time, e.g., ion convection, auroral

Investigation of the occurrence of significant deviations in the magnetopause location: solar-wind and foreshock effects

Abstract. Common magnetopause models can predict the location of the magnetopause with respect to upstream conditions from different sets of input parameters, including solar-wind pressure and the

Distribution of the field−aligned currents in the ionosphere: dawn–dusk asymmetry and its relation to the asymmetry between the two hemispheres

The dynamics of the system of field-aligned currents (FACs) and closing ionospheric Pedersen currents is considered with the use of original processing methods and the data from four substorms of

Hall effect control of magnetotail dawn‐dusk asymmetry: A three‐dimensional global hybrid simulation

Magnetotail reconnection and related phenomena (e.g., flux ropes, dipolarizing flux bundles, flow bursts, and particle injections) occur more frequently on the duskside than on the dawnside. Because
