| Session Description | The Sun, its extended corona, the interplanetary space, the Earth’s magnetosphere, ionosphere, middle and low atmosphere, are all parts of a complex system – the heliosphere. To understand how the variable solar activity affects the Earth’s geomagnetic activity and climate, and the performance and reliability of the increasingly complex space-borne and ground-based technological systems, we need to understand the solar activity itself and its different manifestations, and the sequence of coupling processes between the various parts of the system. This session provides a forum to discuss the chain of processes and relations from the Sun to the Earth’s surface: the origin and long-term and short-term evolution of solar activity, including variations in total and spectral solar irradiance, initiation and temporal variations in solar flares, CMEs, coronal holes, the solar wind and its interaction with the terrestrial magnetosphere, the ionosphere and its connection to the regions below (MLT regions) and above (plasmasphere, magnetosphere and solar wind), the stratosphere, its variations due to the changing solar activity and its interactions with the underlying troposphere, and the mechanisms of solar influences on the lower atmosphere on different time-scales. Particularly welcome are papers highlighting the coupling processes between the different domains in this complex system. |
