Variations in the Plasma Parameters of the Earth's Magnetotail during Substorm Initiation

Grigorenko, E. E.; Kronberg, E. A.; Kozak, L. V. +3 more

A chain of events accompanying the occurrence of a substorm in the Earth's ionosphere and magnetosphere is considered. Features of geomagnetic pulsations and mechanisms of their generation are indicated. Measurements of magnetic field fluctuations from fluxgate magnetometers, as well as the data on temperature, velocity, and concentration of elect…

Spectra of Turbulence during the Dipolarization of the Magnetic Field

Kozak, L.; Petrenko, B.; Kronberg, E. +3 more

The presence of heterogeneity in turbulent processes has been analyzed, and the spectra of turbulence have been obtained for the regions before and during the dipolarization of the magnetic field in the Earth's magnetospheric tail from the measurements of four space vehicles of the Cluster-2 mission (the event of September 21, 2005). The spectral …
