Division on Solar-Terrestrial Sciences

President: Olga Malandraki (st@egu.eu)
Deputy President: Emilia Kilpua (emilia.kilpua@helsinki.fi)

The Division on Solar-Terrestrial Sciences (ST) considers all aspects of solar and heliospheric physics, specifically the solar-terrestrial connection. It covers the physical processes occurring on the Sun, in the solar wind, as well as in Earth’s magnetosphere and ionosphere. Solar activity (e.g. coronal mass ejections, solar flares, solar energetic particle events) and the response of the near-Earth space environment to these solar phenomena are studied on a wide-range of temporal and spatial scales. Data analysis and interpretation of space-borne and ground-based data, as well as theoretical studies and different modelling techniques are used to better our understanding of how our local star defines the neighbourhood that we live in.

The impacts of space weather on the mid-latitude upper atmosphere

The upper atmosphere of Earth is constantly being impacted by the flow of charged particles being released from the sun. This flow (the solar wind) carries with it a magnetic field which distorts and reshapes that of Earth, ultimately resulting in a large amount of electromagnetic space weather energy being channelled into the polar regions. One of the most frequently observed outcomes of this process is the Dungey cycle [Dungey, 1961], which is where the bulk ionised population of upper …


Meet the Early Career Scientists team of our division!

Hi, this is your ST-ECS team. We are a group of Early Career Scientists (ECSs) of the Solar-Terrestrial (ST) division, and we enjoy organizing events and activities with and for ST-ECS, both during the EGU General Assembly and throughout the year. Our aim is to increase the visibility of ECSs and provide you with opportunities for networking. Currently the team is formed by: Dr. Maxime Grandin Maxime is a postdoctoral researcher at the University of Helsinki in Finland. His research …

Current issue of the EGU newsletter

In the December newsletter, researchers share new insights from cold and remote regions on Earth. They found that the total ice growth in the Arctic region cannot offset sea ice loss in summer. This helps improve our understanding of the atmosphere–ice–ocean system in a changing Arctic, and the impact this may have on human life.

We also hear from Francesco Avanzi, researcher in meltwater security who tells us why climate change might threaten water security. And EGU Policy Manager Chloe Hill highlights 5 things that Europe’s scientific community can do to support evidence-informed policymaking!

Lastly, EGU23 abstract submission deadline is fast approaching (10 January 2023). Check your inbox for the next EGU23 monthly Update from our conference organiser Copernicus, arriving early January. If you miss an Update you can subscribe here.
