The alpha-effect and current helicity for fast sheared rotators
V. V. Pipin
We explore the alpha-effect and the small-scale current helicity, for the case of weakly compressible magnetically driven turbulence that is subjected to the differential rotation.…
Analysis of polarized microwave emission of Flare-Productive Active Region 9415
V. M. Bogod, G. B. Gelfreikh, F. Ch. Drago +5
The results of the microwave observations of the Sun made with the RATAN-600 have shown the existence of many types of spectral peculiarities in polarized emission of active region…
Conditions of excitation of magnetospheric convection by the electric current generated in the bow shock
E. A. Ponomarev, P. A. Sedykh, O. V. Mager +1
This paper analyzes the consequences of electric current generation at the front of the Bow Shock (BS) and the dependence of the direction of this current on the IMF. The condition…
Degradation of signals and operation failures of radio engineering satellite systems during geospace disturbances accompanied by abrupt changes in the geomagnetic field
E. L. Afraimovich
During strong magnetic storms, the errors of determination of the range, frequency Doppler shift and angles of arrival of transionospheric radio signals exceeds the one for magneti…
Isolated ionospheric disturbances as deduced from global GPS network
E. L. Afraimovich, E. I. Astafieva
We investigate an unusual class of medium-scale traveling ionospheric disturbances (MS TIDs) of the nonwave type, isolated ionospheric disturbances (IIDs) that manifest themselves…
The evolution of three-dimensionally localized vortices in shear flows. Linear theory
I. G. Shukhman, V. B. Levinski
The evolution of a small-amplitude localized vortex disturbance in an unbounded shear flow with the linear velocity profile is investigated. Based on the exact solution of the init…
