<b>ST25 - Recent Advances in Observations and Modeling of Low and Middle Latitude Ionospheric Electron Density Irregularities</b><br>
<br>
Ionospheric electron density irregularities, rapid spatial and/or temporal changes of the plasma density at local region have been extensively investigated using ground-based and satellite-based observations because of their scientific and practical importance
but there are many open questions. The creation of the irregularities in low and middle latitudes is closely related to the forcing from both below and above and plasma-neutral interaction, and therefore, they provide a tool to investigate the internal physical
processes in the ionosphere-thermosphere (IT) system and IT response to external drivers. On the practical aspect, ionospheric irregularities are important sources of errors in navigation and communication systems, and therefore, specification of them is essential
for the mitigation of their impact on the society. This session aims to provide an opportunity to review our current understanding of ionospheric irregularities in low and middle latitudes, assess recent progress, and discuss the future direction of this field.
The session covers recent observations of ionospheric irregularities such as plasma bubbles, radio scintillations, traveling ionospheric disturbances, sporadic E-layer, etc. The presentation of numerical simulations and prediction of the behavior of the irregularities
using new approaches including deep learning algorithms are also welcomed. Contributions addressing practical aspects (such as forecasting and mitigation) of ionospheric errors induced by plasma irregularities are also sought. <br>
