Electric potential patterns have been obtained from the IZMIRAN electrodynamic model (IZMEM) for northern and southern polar regions during summer, winter, equinox. The is derived a large quantity of high‐latitude ground‐based geomagnetic data (above ± 57° corrected latitude) at all magnetic local time hours. A linear regression analysis technique has used to obtain quantitative response each observatory changes interplanetary field (IMF) components. Since no ionospheric conductivity exists...
A large database of anomalies, registered by 220 satellites in different orbits over the period 1971–1994, has been compiled. For first time, data 49 Russian Kosmos have included a statistical analysis. The also contains set daily and hourly space weather parameters. series analyses made it possible to quantify, for satellite orbits, conditions days characterized anomaly occurrences. In particular, very intense fluxes (>1000 particles cm −2 s −1 sr (pfu) at energy >10 MeV) solar...
Geomagnetic field variations and electromagnetic waves of different frequencies are ever present in the Earth's environment which fauna flora have evolved live. These a very useful tool for studying exploring physics plasma processes occurring magnetosphere ionosphere. Here we ground-based observations natural emissions magnetospheric origin at low frequency (VLF, 3–30 kHz), neither heard nor seen their spectrograms because they hidden by strong impulsive signals (sferics) originating...
The dynamics of the magnetospheric current systems are studied in course specific disturbance on January 9–12, 1997, caused by interaction Earth's magnetosphere with a dense solar wind plasma cloud. To estimate contribution different sources magnetic field to ground measured, dynamic paraboloid model is used. input parameters defined density and velocity, strength direction interplanetary field, auroral AL index. total energy ring particles calculated from balance equation, where injection...
On the basis of digital magnetometers from International monitor auroral geomagnetic effects (IMAGE) and European incoherent scatter (EISCAT) meridional chains in Scandinavia dynamics eastward westward electrojets during main phase magnetic storms are considered. For intense storm on May 10–11, 1992, with Dst = −300 nT, magnetograms subauroral midlatitudinal stations Leningrad, Borok, Moscow were examined. It is found that electrojet center shifts equatorward as | increases. The located at...
A new self‐consistent version of a time‐dependent magnetospheric paraboloid model is presented and tested on the 24–27 September 1998 magnetic storm interval (minimum Dst = −207 nT). The uses DMSP satellite data to identify location inner boundary magnetotail current sheet flux in lobes their variations with time. These inputs plus upstream solar wind dynamic pressure IMF B z values are used iteratively Earth's field during storm. Several interesting results important consequences obtained:...
Abstract. We investigate variations in the location and intensity of auroral electrojets during magnetic storms substorms using a numerical method for estimating equivalent ionospheric currents based on data from meridian chains observatories. Special attention was paid to complex structure their interrelationship with diffuse discrete particle precipitation field-aligned dusk sector. During magnetospheric eastward electrojet (EE) evening sector changes local time cusp latitudes (Φ~77°)...
Abstract. Cluster/EDI electron drift observations above the Northern and Southern polar cap areas for more than seven a half years (2001–2008) have been used to derive statistical model of high-latitude electric potential distribution summer conditions. Based on pattern different orientations interplanetary magnetic field (IMF) in GSM y-z-plane, basic convection (BCP) were derived, that represent main characteristics dependence IMF. The BCPs comprise IMF-independent as well patterns, which...
Abstract Very low frequency (VLF) auroral hiss at Kannuslehto (KAN), Finland, was analyzed with reference to the progress of 98 isolated magnetic substorms measured during winter months 2015–2018. Of these, 91 were accompanied by substorm growth phase. No recorded expansion and recovery phases. We found that observed under rising polar cap (PC) index, showing an increased solar wind energy input into magnetosphere also in 58 65 events studied, KAN located vicinity enhanced field‐aligned...
