For our modern society a topic of highest interest are near-Earth disturbances emanating from the Sun that shape our “Space Weather”. Most important are solar phenomena like flares, coronal mass ejections (CMEs), and stream interaction regions (SIRs). CMEs present massive clouds of magnetized plasma having speeds up to a few thousand km/s, that may propagate over the Sun-Earth distance within less than a day. CMEs are embedded in the ambient solar wind flow which is structured itself due to the interaction between slow and fast wind streams (so-called SIRs). These may interact with the Earth’s magnetosphere and generate disturbances as well in the lower atmospheric layers, which may cause strong geomagnetic effects. Upstream and downstream of the Earth’s bow shock, different processes on different scales are observed which makes Space Weather a highly interdisciplinary field of research. A better understanding of the physical processes involved in the interaction between solar wind flow and CMEs down to the interaction of these large-scale solar wind structures with the magnetic field and atmospheric layers of Earth will enable us to improve models for more reliable forecasts.<div>***********************************************<br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><img src="cid:ii_lezp3mi90" alt="ISWI Seminar Series March2023.png" width="495" height="495"><br></div><div><br></div><div><div dir="ltr" data-smartmail="gmail_signature"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>-------------------------------------------</div><div><div><font face="times new roman, serif"><b>Dra.
