Possible Effect of Stratospheric QBO on The Ionospheric E-Region Current Densities
Abstract
It is known that ionospheric winds cause the ions to drift in the geomagnetic field. This drift set up a current which produces ground-level geomagnetic field variations. In this study, the relationship between stratospheric QBO and the ionospheric E- region current densities (Jx and Jy) for low latitudes (01.22 N, 103.55 E) have been statistically investigated using the multiple regression model. Also the effect of F10.7 solar flux index was included in the investigation. As a result of the investigation using the multiple regression model, it was determine that an increase/a decrease of 1 s.f.u in the F10.7 solar flux caused an increase/a decrease of 1.5x10-2 A/km and 2.5x10-2 A/km on Jx and Jy current density, respectively. On the other hand, an increase/ a decrease of 1 m / s in the QBO caused a decrease/ an increase of 3x10-3 A/km and 4x10-3 A/km on Jx and Jy current densities, respectively.
