Multiscale features in ICMEs and CIRs and Their Space Weather Implications

Interplanetary Coronal Mass Ejections (ICMEs) and Corotating Interaction Regions (CIRs) are central drivers of heliospheric variability and space weather disturbances. The talk will focus on multiscale characterization of ICMEs and CIRs, including the identification of Alfvén waves and kinetic scale waves, planarity features, and thermodynamic studies through the polytropic index. Local structures such as current sheets, small-scale flux ropes, highly fluctuating magnetic field patches, and high-temperature regions inside ICMEs and CIRs will also be discussed. Finally, the talk will highlight the linkages between these multiscale plasma processes and their implications for space weather, particularly their role in driving magnetospheric disturbances.
