Enhanced ionospheric plasma bubble generation in more active ITCZ

摘要: A close link between the atmospheric Intertropical Convergence Zone (ITCZ) and ionospheric plasma bubble has been proposed since last century. But this relationship often appeared to be less than convincing due simultaneous roles played by several other factors in shaping global distribution of bubbles. From collaborative radar multibeam steering measurements at Kototabang (0.2°S, 100.3°E) Sanya (18.4°N, 109.6°E), conducted during September–October 2012 2013, we find that total numbers nights with (i.e., occurrence rates) two closely located longitudes (Kototabang Sanya) are comparable. interestingly, number locally generated generation rate) over is clearly more Sanya. Further analysis reveals a active ITCZ situated around longitude Kototabang. We surmise enhanced could caused higher gravity wave activity associated ITCZ.
