  • control of recent european surface climate change by Atmospheric Flow
    Geophysical Research Letters, 2009
    Co-Authors: Robert Vautard, Pascal Yiou

    Abstract:

    [1] Many changes in European surface climate have occurred over the past decades, but most of the processes driving them are not identified. In particular, the role of Atmospheric Flow in driving surface trends needs to be evaluated to better predict future regional climate. We compare observed surface climate trends with those constructed from daily Flow analogues. We find that during the last 60 years Atmospheric circulation changes are the main drivers of surface weather trends in winter, but not in summer where temperature strongly interacts with the water cycle. For instance, increasing anticyclonic conditions control the decreasing summer rainfall frequency, but rainfall amount and cloud cover have not decreased accordingly, because individual rainfall events bring more rain now than decades ago. Over the past three decades the control by Atmospheric Flow changes has weakened, indicating evolutions in the processes steering European surface climate change.

  • Inconsistency between Atmospheric dynamics and temperatures during the exceptional 2006/2007 fall/winter and recent warming in Europe
    Geophysical Research Letters, 2007
    Co-Authors: Pascal Yiou, Robert Vautard, Philippe Naveau, Christophe Cassou

    Abstract:

    [1] Europe witnessed unprecedented warmth persisting throughout fall and winter 2006–2007, with only a few cold breaks. Whether this anomaly and recent warming in Europe can be linked to changes in Atmospheric dynamics is a key question in the climate change prospective. We show that despite the fall/winter Atmospheric Flow was favorable to warmth, it cannot explain alone such an exceptional anomaly. Observed temperatures remained well above those found for analogue Atmospheric circulations in other fall and winter seasons. Such an offset is also found during the last decade and culminates in 2006/2007. These observational results suggest that the main drivers of recent European warming are not changes in regional Atmospheric Flow and weather regimes frequencies, contrasting with observed changes before 1994.
