Title: Space Weather Predictability

Abstract:
Space weather encompasses all conditions and events occurring at the Sun, in the solar wind, in near-Earth space, and in the upper atmosphere that can impact both space-borne and ground-based technological systems, as well as human activities. These effects can manifest acutely or persist over the long term. Despite decades of extensive research involving measurements, modelling, and simulations, our understanding of space weather remains incomplete. While significant progress has been made in identifying long-term correlations between solar eruptions and their effects on geospace, it’s crucial to acknowledge the existence of exceptions to these patterns. Additionally, similar solar eruptions or interplanetary disturbances can lead to vastly different outcomes in geospace. Furthermore, the diverse nature of geospace effects underscores the dependency on various types of solar eruptions or interplanetary disturbances. The limitations imposed by these deviations from deterministic causality pose significant challenges in accurately nowcasting and forecasting space weather events. In this seminar, selected aspects of space weather predictability will be explored, with a particular focus on understanding the factors influencing the formation of relativistic electrons in the outer Van Allen belt.
