Space Climate 7 Meeting Abstract
Space weather impacts and predictions: relevant spatial and temporal scales
Antti A Pulkkinen (NASA Goddard Space Flight Center)
Space weather impacts our modern infrastructure in a variety of ways. The impacts are an interplay between the dynamic space environment and the response modes of the impacted systems. The response modes are highly dependent on the engineering details of the system such as transformer design in the case of high-voltage power transmission. The interplay between natural phenomena and system response gives rise to complex dynamics that operate at a wide range of relevant spatial and temporal scales. It is imperative that we have handle of the full range of these scales to fully understand and mitigate the space weather hazard.
In this paper, I will discuss some basic ideas behind space environment vs responses of a range of systems of interest, including humans in space. I will discuss the response modes in the context of relevant spatial and temporal scales that need to be resolved for understanding and predicting the ultimate impacts. Importantly, major progress has been made over the past decade to model the space environment from first-principles. I will discuss how these advancements have enabled better understanding of the hazard and new predictive capabilities.
