This session focuses on how the equatorial ionospheric plasma drift responds to magnetic storms, what determines the generation of equatorial spread F and plasma bubbles, how significantly seeding perturbations affect the generation of plasma bubbles, how the occurrence of equatorial spread F depends on longitude and solar activity, and how ionospheric scintillation is correlated with spread F irregularities. We welcome observational and simulation studies that address these topics and that aim to improve the current capability of forecasting low-latitude ionospheric disturbances, spread F irregularities, and scintillation activities.<o:p></o:p></span></p><p class=MsoPlainText><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></p><p class=MsoPlainText><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Thank you.<o:p></o:p></span></p><p class=MsoPlainText><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></p><p class=MsoPlainText><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Conveners<o:p></o:p></span></p><p class=MsoPlainText><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Chaosong Huang, AFRL, US<o:p></o:p></span></p><p class=MsoPlainText><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'>Endawoke Yizengaw, Boston College, US<o:p></o:p></span></p></div></body></html>
