No.: EPSL-D-07-00839 Title: Evidence for Solar Forcing in Variability of Pressures and Temperatures in Europe Authors: Elena Blanter; Jean-Louis Le Mouël; Mikhail Shnirman; Vincent Emmanuel Courtillot, PhD Journal: Earth and Planetary Science Letters Dear Phil, This is the second part of my request. I hope you can help. Since the two papers are closely related, I would very much appreciate your views on the merit of two separate papers. If you are available to review this manuscript, please click on the link below: http://ees.elsevier.com/epsl/l.asp?i=23850&l=9KZXA957 If you accept this invitation, I would be very grateful if you would return your review within 21 days. If you are not available to review this manuscript, please click on the link below. We would appreciate receiving suggestions for alternative reviewers: http://ees.elsevier.com/epsl/l.asp?i=23849&l=9H07Q3SG If you prefer, you may register your response to this invitation online, by accessing the Elsevier Editorial System for Earth and Planetary Science Letters as a REVIEWER: url: http://ees.elsevier.com/epsl/ Your username is: PJones-929 Your password is: jones26322 Please select the "New Invitations" link on your Main Menu, then choose to "Accept" or "Decline" this invitation, as appropriate. If you accept this invitation, you may submit your completed review online at the above URL. There you will find spaces for confidential comments to the editor and comments for the author. To assist you in the reviewing process, I am delighted to offer you full access to Scopus* for 30 days. With Scopus you can search for related articles, references and papers by the same author. You may also use Scopus for your own purposes at any time during the 30-day period. If you already use Scopus at your institute, having this 30 day full access means that you will also be able to access Scopus from home. Access instructions will follow once you have accepted this invitation to review *Scopus is the world's largest abstract and citation database of research information and quality internet sources. With kind regards, Rob D. van der Hilst Editor Earth and Planetary Science Letters ABSTRACT: We study the solar signature in the temporal evolution of disturbances of European temperature and pressure in the 20th century, using long series of daily data provided by meteorological stations. We use three independent indices of solar activity which exhibit similar evolution after 22-yr running averaging. With the same 22-yr averaging, disturbances of temperature and pressure are found to be dominated by wintertime perturbations. The solar signature in the wintertime disturbances is especially strong throughout the 20-th century and does not weaken in the last decades, contrary to what happens for whole year data. Disturbances of minimal temperature, pressure and wind direction in the wintertime display remarkable similarity: All these meteorological (actually almost climatic, given the 22-yr averaging) characteristics closely follow the solar signature as far as the winter season is concerned, even when little or no correlation is observed for the whole year. We discuss the particular features of European climate and speculate on how solar forcing may manifest itself in other regions.
