             abstract = "The generation and development of ionospheric irregularities is an 
                         important topic of study in space weather, particularly due to 
                         their adverse effects on navigation positioning systems and 
                         trans-ionospheric communications. To improve our prediction 
                         capabilities, a comprehensive understanding of their variability 
                         during different geomagnetic conditions is important. The purpose 
                         of this research is to analyze the generation or inhibition of 
                         ionospheric irregularities in the F region over South America 
                         during geomagnetic storms. To conduct the analysis, we use GOLD OI 
                         135.6 nm radiance maps, ICON IVM ion density and vertical drift, 
                         ICON FUV data and ROTI maps. Additionally, we consider ICON MIGHTI 
                         wind data (red line emission) to study the role of the neutral 
                         wind. We examine the presence of irregularities during three 
                         storms: November 3, 2021; January 14, 2022, and February 3, 2022. 
                         Two of them (November and February) showed inhibition of plasma 
                         bubbles over the east of Brazil, whereas, during the January 
                         storm, generation of plasma bubbles was observed over the same 
                         region. The storm-time electric fields might play an important 
                         role in the development of irregularities. The potential drivers 
                         of the plasma bubbles variability during disturbed geomagnetic 
                         conditions will be examined using wind profiles provided by ICON 
                         MIGHTI.",
