Equatorial spread-F

Journal of Atmospheric and Terrestrial Physics, 1959
Abstract Spread- F conditions have been examined for six low-latitude stations—Dakar, Khartoum, Djibouti, Ibadan, Nairobi and Leopoldville. It is shown that, contrary to the general view, occurrence of disturbed magnetic conditions inhibits the occurrence of spread- F layers during the southern solstice at all these stations.

Duration of equatorial spread F

Nature, 1975
IT is well established1–3 that the spread-F phenomenon, which is observed as diffuse echoes on the ionograms is a common feature during night time between the dip latitudes 20°N and 20°S. Based on the study of ionograms and published monthly f0F2 bulletins, morphological features of spread F have been reported for several equatorial stations1,4–10 ...

Artificial control of equatorial spread-F

Journal of Atmospheric and Terrestrial Physics, 1978
Abstract We have studied the influence of a large amplitude electric field oscillating near the upper hybrid frequency on the dispersion characteristics of low frequency Rayleigh-Taylor modes and collisional drift modes. Since these modes have been proposed as principal constituents of spread- F , we investigate the conditions for the parametric ...
