| Zusammenfassung |
| The study of the
robust features of the magnetosphere is motivated both by new "whole
system" approaches, and by the idea of "space climate" as
opposed to "space weather". We enumerate these features for the
AE index, and discuss whether self-organised criticality (SOC) is the most
natural explanation of the "stylised facts" so far known for AE.
We identify and discuss some open questions, answers to which will clarify
the extent to which AE's properties provide evidence for SOC. We then
suggest an SOC-like reconnection-based scenario drawing on the result of
Craig (2001) as an explanation of the very recent demonstration by Uritsky
et al. (2001b) of power laws in several properties of spatiotemporal
features seen in auroral images. |
