Annales Geophysicae (ANGEO) is an international, multi- and inter-disciplinary scientific open-access journal in the field of solar–terrestrial physics. ANGEO publishes original articles and short communications (letters) in the sciences of the Sun–Earth system, including the science of space weather, the solar–terrestrial plasma physics, and the Earth's atmosphere.

ANGEO manuscript submission will be closed for new submissions on 20 December 2017 due to the change to an interactive open-access journal. We welcome new submissions from 2 January 2018. Thank you very much for your understanding!

Transition of ANGEO to an interactive journal

07 Dec 2017

From January 2018 on, Annales Geophysicae (ANGEO) will change to an interactive open-access journal applying the public peer review and interactive public discussion concept. In addition, the EGU Planetary and Solar System Sciences Division will be represented through an extension of ANGEO's subject areas.

New article processing charges for ANGEO

05 Dec 2017

From 1 January 2018 Annales Geophysicae (ANGEO) will increase the article processing charges.

New institutional agreement between the PIK and Copernicus Publications

24 Aug 2017

Authors from the Potsdam Institute for Climate Impact Research (PIK) will profit from a new institutional agreement with Copernicus Publications starting 23 August 2017. The agreement which is valid for the first author enables a direct settlement of article processing charges (APCs) between the PIK and the publisher.

The sequence of phenomena consisting of solar flares, coronal mass ejections (CMEs), auroral substorm, and geomagnetic storms is mostly a manifestation of electromagnetic energy dissipation. Thus, first of all, it is natural to consider each of them in terms of a sequence of power supply (dynamo), power transmission (electric currents/circuits), and dissipation (mostly observed phenomena), i.e., as an input-output process and the electric current line approach.

Results from a high-altitude balloon experiment conducted from a low-latitude station in India are presented in this work. The objectives of this experiment were to probe and understand the processes driving the various electric field sources at low latitudes. During this experiment, electric fields in the range of 5–6 mV m−1 were observed at the balloon float altitude of 35 km. Atmospheric waves of few 100 km horizontal wavelength are suggested to be a potential source of these electric fields.

A new type of wave has been detected by the magnetometer of the Rosetta spacecraft close to comet P67/Churyumov-Gerasimenko. We provide the analytical model of this wave excitation from linear perturbation theory. A modified ion-Weibel instability is identified as source of this wave excited by a cometary current. The waves predominantly grow perpendicular to this current. A fan-like phase structure results from superposing the strongest growing waves in a cometary rest frame.

This study presents an investigation on the occurrence of fast flows in the magnetotail using the complete available data set of the THEMIS spacecraft for the years 2007 to 2015. First, basic statistical findings concerning velocity distributions, occurrence rates, group structures and key features of 16 000 events are presented using Superposed Epoch and Minimum Variance Analysis techniques.

The method of electric field mapping along geomagnetic field lines, derived in an accompanying paper, is applied to the International Geomagnetic Reference Field. Formulae for the geomagnetic field gradient tensor are derived and these are used in a software package developed to map the electric field. A number of examples are presented illustrating the method. The method will be of importance in conjugate studies of ionospheric convection when the external magnetic field can be neglected.
