Flares, Coronal Mass Ejections (CMEs) and associated shock waves are of key interest in the field of solar-terrestrial relations. Interplanetary CMEs and their associated shock waves are the main drivers of geomagnetic storms. High speed solar wind streams emanating from coronal holes also have a big influence on geospace, in particular outside of solar maximum when CMEs are more scarce. They are also important drivers of relativistic electron enhancements in the radiation belts surrounding the Earth. Flares in turn can have an important impact (UV radiation, particles) on the Earth's atmosphere.
Recent remote observations and modelling studies have shown that CMEs can drive shock waves very low in the solar corona, which, in turn, may produce significant fluxes of solar energetic particles (SEP).
There is thus a strong need for realistic and data-driven modelling of solar wind, flares and CMEs using a variety of theoretical, physics-based and semi-empirical models, such as heliospheric models like EUHFORIA, ENLIL and SUSANOO.

In this session, we invite observational, theoretical, and modelling contributions that address the following topics:
• Flares, the coronal dynamics of CME and shock waves and their related production of SEPs
• CME propagation in the heliosphere, the interaction of ICMEs with Earth and/or with other planets
• The link between CMEs and ICMEs
