Dayside ionospheric convection changes in response to longperiod interplanetary Magnetic field oscillations Determination of the ionospheric phase velocity
Ground magnetic field perturbations recorded by the CANOPUS magnetometer network in the 7 to 13 MLT sector are used to examine how reconfigurations of the dayside polar ionospheric How take place in response to north-south changes of the IMF. During the 6-hour interval in question IMF Bz oscillates between_+7 nT with about a 1-hour period. Corresponding variations in the ground magnetic disturb...

متن کاملEvaluating the Changes in Alpha-1 Band Due to Exposure to Magnetic Field
Introduction Increase in alpha band is observed when blood perfusion in frontal area of head decreases. The present study evaluated some changes in the alpha band particularly, alpha-1 of frontal and central areas of the head, when several areas were exposed simultaneously to magnetic field. Materials and Methods Five points of head (F3, F4, Cz, T3, and T4) of twenty healthy male participants w...
متن کاملResponse of the magnetosphere-ionosphere system to a sudden southward turning of interplanetary magnetic field
[1] A sudden southward turning of interplanetary magnetic field (IMF) is simulated by the University of Michigan’s BATS-R-US model. The main goal of this study is to determine the time delay as well as physical processes between when an IMF discontinuity reaches the bow shock, when reconnection is initiated at the magnetopause, and when the ionosphere starts to react. While observations or empi...
متن کاملTransient changes in magnetospheric‐ionospheric currents caused by the passage of an interplanetary shock: Northward interplanetary magnetic field case
[1] We use results from a global MHD simulation to study the interaction of an interplanetary shock with the Earth’s magnetosphere for a northward interplanetary magnetic field orientation. We connect intensifications of the transient northward Bz (NBZ) and Region 1 currents in the ionosphere with the appearance of two strong dynamo regions in the magnetosphere: the first on the high‐latitude m...
