Evolution of total electron content and slab thickness at Tucumán, Argentina during some geomagnetic storms

Abstract

The evolution of total electron content and slab thickness at Tucumán, Argentina, during the geomagnetic storms of 12 June 1982, 16 July 1982, 6 August 1982, 10 December 1982 and 4 February 1983 is studied. It is found that the storm effects present a good agreement with so-called "regular" storms. The role of electric fields and thermospheric winds is discussed
