Abstract Magnetospheric convection is a fundamental process in the coupling of solar wind, magnetosphere, and ionosphere. Recent studies have shown that dayside magnetopause reconnection drives magnetospheric convection, progressing from to nightside within approximately 10–20 min response southward turning interplanetary magnetic field. In this study, we use global magnetohydrodynamic (MHD) simulations investigate influence ionospheric conductance on dayside‐driven convection. We conduct...

Abstract In this study, a new analytical model to describe the time‐dependent subsolar magnetopause motion under interplanetary magnetic field (IMF) southward turning has been developed. This model, based on scenario of erosion due reconnection, can be approximated by both linear and non‐linear functions. The function is simplified assumption constant IMF, derived assuming that decays exponentially. limit short time, essentially same as function. By comparing with global magnetohydrodynamic...
Abstract In this study, the neutral wind observations from Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) instrument onboard Ionospheric CONnections (ICON) are used to investigate longitudinal structure of zonal between 100 and 300 km during daytime. The four-peaked in distribution June August is visually clear whole altitudinal range. wavenumber 1–4 patterns (WN1–WN4) extracted, altitude–month distributions WN1–WN4 their contributions compared. amplitudes...
In this study, we simulate the Solar Wind Charge Exchange (SWCX) soft X-ray emissions at dayside magnetopause by using magnetohydrodynamic (MHD) and Test-Particle (TP) models. Due to single fluid description, MHD model is unable resolve particle kinetic effects or distinguish magnetospheric plasma solar wind plasma. We investigate these with TP model. As does not self-compute magnetic electric field, field data obtained from OpenGGCM PPMLR are used as input The emissivity maps simulated pure...
Abstract In this study, we simulate the Solar Wind Charge Exchange (SWCX) soft X‐ray emissions at dayside magnetosheath and cusps by using magnetohydrodynamic (MHD) LAtmos TEst Particle (LaTeP) models. MHD models are unable to resolve particle kinetic effects, such as different behaviors of ions with q/m, or distinguish magnetospheric plasma from solar wind plasma. We investigate these effects LaTeP model. As model does not self‐compute magnetic electric field, field data obtained Open...
