Energetic Particle Influence on polar vortex under Climate Change

Energetic particle precipitation from space into the atmosphere leads to ozone destruction in the wintertime polar stratosphere. This influences the polar vortex and ground weather variations during winter. These effects also depend on the atmospheric wave activity and meridional circulation, which both will likely increase due to climate change. EPICC project (Energetic Particle Influence on polar vortex under Climate Change) considers for the first time how the particle precipitation effect changes due to the climate change. The research uses both past observations and climate modeling for possible scenarios of future climate change. We will develop new reconstructions of past and future particle precipitation with deep learning networks. The results will improve our understanding on joint influence of solar activity and climate as well as long-term predictions of climate and weather. The site of research is the Space Physics and Astronomy research unit of University of Oulu.
