Study of Geomagnetic Field Variations at Low Latitude of African Equatorial Region
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 4
Abstract
Abstract. Hourly values of horizontal (H) field component of geomagnetic field at Mbour obtained from World Geomagnetic Data Centre – Kyoto (WDC-kyoto) and solar wind parameters obtained from OMNIWEB website during several storm events in 2004 and 2010 were used to investigate the influence of solar wind parameters on H-component at a low latitude station in Africa. The results show a close correspondence of rapid changes between H-component and solar wind parameters during initial phase, main phase and recovery phase of geomagnetic storm. Further investigation using spectral analysis techniques as well as regression analysis showed that solar wind parameters is a strong candidate in triggering geomagnetic storm which affects H-component of the geomagnetic field
