Investigation of ground magnetic perturbation in the midlatitude during active geomagnetic condition

Abstract

The present paper aims at ground magnetic perturbation forecast in the midlatitude. Specifically, the assessment of ground magnetic perturbation in the middle east is of particular interest. More than 20 events including geomagnetic activity types of various orders from 2000 to 2018 are employed in the present work. The study evaluated both geomagnetic indices, real-time magnetic field, and solar wind components measured by the satellites. Detailed investigation and comparison of the data are presented. The Bz and By components of the interplanetary magnetic field (IMF) are investigated. The change of polarity, time duration, maximum amplitude, and characteristics including structures in IMF time series are investigated. The ground magnetic perturbation for several stations in the middle east and their correlation with solar wind properties are discussed. The prediction possibility of magnetic perturbation in the midlatitude is discussed and evaluated. The geomagnetic state variables are taken into account to assess the post-processed indices for analyzing the magnetic anomalies associated with solar winds. A conclusion based on the analyzed data for the prediction of magnetic perturbation in the midlatitude is derived.
