Some preliminary results concerning periods around local sunrise are presented. A cIear fading effect, due to the defocusing phenomena in the upper ionosphere, has been observed in different seasons159 126 - PublicationOpen AccessOn the origin of medium-period ionospheric waves and their possible modelling: a short review(1997-10)
; ; ; ;Dominici, P.; Dipartimento di Fisica, Università La Sapienza, Roma, Italy ;Cander, L. R.; Geomagnetic Institute, 11306 Grocka, Belgrade, Yugoslavia ;Zolesi, B.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia; ; This article introduces the concept of ionospheric waves with periods from about 15 min to about 4 h as one of the acoustic-gravity wave-induced phenomena. The existence of these medium-period ionospheric waves in the various ionospheric layers is supported by the results of a data analysis which has shown remarkable characteristics in occurrence and direction of the waves with a period not longer than about 2 h. The explanation offered is based on the assumption that a unique phenomenon capable to launch acoustic-gravity waves related to such ionospheric waves is the sudden change in physical conditions of the atmosphere due to the passage of the solar terminator.143 156 - PublicationOpen AccessMy first fifty years in ionospheric research(1998-11)
