Аннотация: For analyses of the trough occurrence in TEC the latitudinal profiles formed from TEC maps over Europe have been used. GPS/GLONASS observations collected by International European Permanent Network (EPN) were used to create TEC maps. More than 180 stations from Europe were included in the analysis. The large number of GPS stations in Europe provides good coverage for GPS data and enable high-accuracy TEC maps with a temporal resolution of 5 min. The profiles were created with resolution of 1o at fixed longitude of 20oE in latitudinal range 40-74°N. We analyzed the dynamics of trough minima location for winter (December 2015), equinox (March 2015) and summer (June, 2015) and accordingly storm days December 20, March 17 and June 22, 2015. During winter and equinox storms the trough is registered at latitudes of 47-52o N.
