First observation of quasi-2-day oscillations in ionospheric plasma frequency at fixed heights by D. Altadill, J. G. Solé, E. M. Apostolov

“…The largest enhancements of the oscillation occurred during early June, July and early August; i. e., near and after the summer solstice when the 2-day wave in the middle neutral atmosphere typically displays its largest activity in the Northern Hemisphere. The results obtained may help us understand better the possible influencing mechanisms between the 2-day wave in the middle neutral atmosphere and the ionospheric quasi-2-day oscillations.…”

A Study of the subtropical high pressure 500 hPa level changes in the Iran's atmosphere with emphasis on climate change by Yousef Alipour, Zahra Hedjazizadeh, Mehry Akbary, Mohammad Saligheh

“…Azores subtropical high pressure is accounted as the most striking and permanent features of tropospheric circulation in the Northern Hemisphere subtropical region and Iran. Assessing the published sources about the subtropical high-pressure variations showed that a comprehensive research of the high-pressure changes is needed in different seasons of the year. …”
