The correlation study of geomagnetic field variations at interhemispheric conjugate points in high latitude regions

In the Earths Magnetosphere-Ionosphere (MI) system, both northern and southern upper atmospheric regions are linked to the magnetosphere through magnetic fields. The interhemispheric asymmetries in these regions are shown in observational and modeling studies with various signatures, such as magnetic pulsations, field-aligned currents, auroral particle precipitation, etc. It is crucial to understand how each source of asymmetry interacts with each other and how asymmetric structures incorporate this information into predictive models. In this study, the magnetic field variations observed at East Antarctica and West Greenland are analyzed to identify the spatiotemporal characteristics and magnitudes of interhemispheric asymmetries. The correlations surveys of the magnetic field variations at magnetically conjugated stations are calculated and compared under different Solar Wind-Magnetospheric-Ionospheric (SWMI) conditions, to investigate the causes of asymmetric processes in the SWMI coupling system. These results would be helpful to conduct idealized simulations with controlled external drivers.
