Seasonal Variation of Worldwide Solar Quiet of the Horizontal Magnetic Field Intensity

Numerous investigations have been carried out on many geomagnetic phenomena with a view of understanding the ionosphere. Solar Quiet (Sq) is caused by electric currents induced in the Earth by the external source. We studied the variations of Sq over the various seasons Winter (November, December, January and February), Summer (May, June, July, August), Autumn (September, October) and Spring (March, April), using data from 64 geomagnetic stations for the year 1996 across the globe. The seasonal variations were studied across various latitudes and longitudes. Results show that Sq(H) exhibits transient variations with varying amplitude according to seasons of the year.
