Dipole tilt effects on the magnetosphere‐ionosphere convection system during interplanetary magnetic field BY‐dominated periods: MHD modelingDownload
Using numerical magnetohydrodynamic simulations, we examine the dipole tilt effects on the magnetosphere-ionosphere convection system when the interplanetary magnetic field is oblique northward (B-Y = 4 nT and B-Z = 2 nT). In particular, we clarify the relationship between viscous-driven...
On the basis of magnetohydrodynamic simulation results for northward interplanetary magnetic field ( IMF) and significant dipole tilt, we describe internal reconnection processes that occur earthward of the magnetopause subsequent to magnetopause reconnection. We discuss the associated...
Origin of the interhemispheric potential mismatch of merging cells for interplanetary magnetic field BY‐dominated periodsDownload
When the dawn-to-dusk component of the interplanetary magnetic field (IMF B-Y) is dominant, ionospheric convection exhibits a basic two-cell pattern with significant dawn-dusk and interhemispheric asymmetries. For IMF B-Y > 0 the duskside merging cell potential in the Northern Hemisphere is much...
