摘要: Abstract The inspection of ionospheric sounding data and ground-based geomagnetic data, recorded at Grocka observatories (44°38′N, 20°46′E, I=61°), from 1978–1982, shows that there is correspondence between periods the sporadic E day-time cycles activity Sq(H) variation. This an indication formation variation are controlled by action same wind modes. coincidences were found events extremely dense E, (fbEs ⩾ 10 MHz), small size disturbances H-component values. A possible explanation these could be current-carrying properties sequential contribute to changes conductivity height profiles so affect current flow in dynamo region.
