Title: On the cause of fore-noon & post-noon bite-outs in foF2
Abstract: A seasonal study of foF2 data of two Pakistani ionospheric stations viz: Karachi (24.95°N, 67.14°E) and Islamabad (33.75°N, 72.87°E) for the period from March 1982 to February 1983 shows that the percentage occurrence of the fore-noon and post-noon bite-outs travelling from a higher latitude (33.75°N) to a lower one (24.95°N) is maximum in Winter and minimum in Summer. A reversed seasonal trend is observed for the bite-outs which travelled from lower to higher latitudes. The propagation of fore-noon and post-noon bite-outs from higher to lower latitudes and vice versa gives a clue that the possibility of their production by Ē × B̄ drift may be ruled out and that a plausible cause of the bite-outs may be meridional winds (equatorward/poleward winds).
