| Heat waves are among natural hazards with the most severe consequences for
human society, including pronounced mortality impacts in mid-latitudes.
Recent studies have hypothesized that the enhanced persistence of
atmospheric circulation may
affect surface climatic extremes, mainly the frequency and severity of heat
waves. In this paper we examine relationships between the persistence of the
Hess-Brezowsky circulation types conducive to summer heat waves and air
temperature anomalies at stations over most of the European continent. We
also evaluate differences between temperature anomalies during late and
early stages of warm circulation types in all seasons. Results show that
more persistent circulation patterns tend to enhance the severity of heat
waves and support more pronounced temperature anomalies. Recent sharply
rising trends in positive temperature extremes over Europe may be related to
the greater persistence of the circulation types, and if similar changes
towards enhanced persistence affect other mid-latitudinal regions, analogous
consequences and implications for temperature extremes may be expected. |
