Space Weather: Forecast, Hindcast or Nowcast? — •May-Britt Kallenrode — Universität Osnabrück, Fachbereich Physik, Barbarastr. 7, 49080 Osnabrück, Deutschland

Different effects of the Sun and the interplanetary medium on Earth's natural and technical environment are summarized under the term Space Weather. As with ordinary weather, science tries to observe and understand in real time (nowcast), tries to make predictions on different spatial and temporal scales (forecast), and tries to understand long term evolutions in the sense of a space climatology (hindcast). This talk will try to sort our present understanding of space weather in terms of physical processes and statistical observations. With the complexity of different players in space weather in mind, the possibilities and limitations of a space weather forecast will be explored.
