The results reported in these papers derive from a doctoral thesis (Dall’Amico 2005). We wish to thank Prof. Klaus X. Elsässer, Prof. M. Dameris, and many colleagues at the Meteorological Institute of the University of Munich who spent time in fruitful discussions with us. In particular, discussions with the late Dr. Wolfgang Ulrich were helpful. We thank Dr. Chris Ferro for his statistical advice. Several suggestions by Dr. Katie Coughlin, Prof. Lesley J. Gray, and anonymous reviewers helped to improve this paper. We thank the ECMWF for the development of ERA-40 and the Herberg Institute of Astrophysics, Canada, for making the time series of the 10.7-cm solar flux available on the internet. Financial support was provided by the German Ministry of Education and Research and the German Aerospace Center within KLIMESTO, a project of the German Climate Research Program, Contract 01LD0033.
