Magnetohydrodynamic simulation of the interaction 1 between two interplanetary magnetic clouds and its 2 consequent geoeffectiveness : 2 . Oblique collision

Magnetohydrodynamic simulation of the interaction between two interplanetary magnetic clouds and its consequent geoeffectiveness: 2. Oblique collision

The numerical studies of the interplanetary coupling between multiple magnetic clouds (MCs) are continued by a 2.5-dimensional ideal magnetohydrodynamic (MHD) model in the heliospheric meridional plane. The interplanetary direct collision (DC) / oblique collision (OC) between both MCs results from their same/different initial propagation orientations. Here the OC is explored in contrast to the ...

Magnetohydrodynamic Simulation of the Interaction between Interplanetary Strong Shock and Magnetic Cloud and its Consequent Geoeffectiveness 2: Oblique Collision

Numerical studies of the interplanetary “shock overtaking magnetic cloud (MC)” event are continued by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane. Interplanetary direct collision (DC)/oblique collision (OC) between an MC and a shock results from their same/different initial propagation orientations. For radially erupted MC and shock in solar corona, the or...

Magnetohydrodynamic Simulation of the Interaction between Interplanetary Strong Shock and Magnetic Cloud and its Consequent Geoeffectiveness

Numerical studies have been performed to interpret the observed “shock overtaking magnetic cloud (MC)” event by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane. Results of an individual MC simulation show that the MC travels with a constant bulk flow speed. The MC is injected with very strong inherent magnetic field over that in the ambient flow and expands ra...

Dipole tilt effects on the magnetosphere‐ionosphere convection system during interplanetary magnetic field BY‐dominated periods: MHD modeling

[1] Using numerical magnetohydrodynamic simulations, we examine the dipole tilt effects on the magnetosphere‐ionosphere convection system when the interplanetary magnetic field is oblique northward (BY = 4 nT and BZ = 2 nT). In particular, we clarify the relationship between viscous‐driven convection and reconnection‐driven convection. The azimuthal locations of the two viscous cell centers in ...
