We are indebted to S. Leder (FUB) and D. J. Shea (NCAR) for their skilled handling of the data and the computations of correlations and eigenvectors. The research was supported by Bundesministerium für Bildung und Forschung, Project 07 VKV 01/1/14 (Climate), and by the National Center for Atmospheric Research. K. Mo (CFC/NOAA) and R. Jenne (NCAR) have kindly supplied the NCEP–NCAR data. The solar-flux data are from the Space Environment Center, NOAA, Boulder, Colorado.
