Title: Coupling of the Solar Wind and the Magnetosphere
Abstract: The field orientation in transient and co-rotating structures that are ejected from the Sun and evolve in interplanetary space is crucial in reconnection between the solar wind and the magnetosphere. However, fluctuations in the magnetic field and/or enhancements in plasma density may influence the coupling between the solar, interplanetary, and magnetospheric fields. Consequently, the geo-effectiveness of solar wind structures with enhanced field variance and density are likely to increase. We study the effects of both enhanced field fluctuations and enhanced plasma density on the magnetic reconnection/coupling efficiency. We consider solar plasma and field properties, particularly the field fluctuation and plasma density before, during, and after the interplanetary events with geospace consequences. Considering the geo-effectiveness of different magnitude as a measure of the coupling efficiency and reconnection rate, we study the influence of these enhancements on the solar wind–magnetosphere coupling efficiency, during southward field orientation within the interplanetary structures.
