Study of Equatorial Electrojet using Chain of Stations along the Dip Equator

Abstract

This study examined Equatorial electrojet (EEJ) in four longitudinal zones namely; Addis-ababa (AAE) in East African sector, Huancayo (HUA) in South America, M’boh (MBO) in West African sector and Guam (GUA) in Pacific Ocean. The study shows that EEJ is higher in the South American Sector than any of the longitudinal sectors studied. It was interestingly shown that all the stations had their peaks in the noontime. These results suggest that in the entire longitudinal sectors the EEJ has its maximum in the noontime. The result also shows that EEJ is mostly observed during March and April, reduces in strength in the months of May, June, July, August and resurfaces again between September and October. Seasonal variation shows that the E-season is higher than D-season and J-season in all the stations studied.
