From Initiation to Impact: Understanding CMEs as Drivers of Space Weather
Session ID#: 251191
Session Description:
Understanding the life cycle of CMEs—from their initiation at the Sun, their propagation through the heliosphere, to their geoeffective consequences at Earth—is essential for accurate space weather forecasting and mitigation strategies. Observations from multiple vantage points, such as those from PSP, SolO, STEREO, SOHO, Aditya L1, the recent PUNCH mission and the upcoming ESA Vigil mission, along with ground-based radio observatories, enable three-dimensional reconstruction of CME morphology, kinematics, and their interaction with the ambient solar wind. Advances in numerical MHD simulations and the incorporation of AI/ML techniques into these models are revolutionizing space weather prediction. We invite contributions aimed to comprehensively investigate CME evolution using synergistic approach that combines multi-wavelength, multi-vantage point observations, numerical modelling, and AI/ML-based methodologies. A special focus is given to CME-CME interactions, which can lead to complex ejecta with enhanced geoeffective signatures, often resulting in more intense geomagnetic storms. (e.g., May and October 2024 storms).
