Exploring the Substructures of Coronal Mass Ejections (CMEs) and Their Space Weather Impacts
Research Interests
CMEs' Substructures in the Heliosphere: Origin and evolution of CMEs' substructures, such as shock, sheath, and CME-associated magnetic flux rope; turbulence across shocks; non-coherency in CME flux rope at mesoscales; asymmetric and instantaneous expansion of CME flux rope; formation of different types of interplanetary shocks; CME-CME interactions
Space Weather: Storm sudden commencement; geomagnetic storms; Forbush decreases; acceleration of SEPs due to shocks
An approach to identify the compressed region of the magnetic cloud (MC) and mark the MC axis
