Multi‐indices analysis of southern Scandinavian storminess 1780–2005 and links to interdecadal variations in the NW Europe–North Sea region
Abstract Extra‐tropical cyclone frequency and intensity are currently under intense scrutiny because of the destruction recent windstorms have brought to Europe, and because they are a major meridional heat transport mechanism that may respond to differential latitudinal warming trends.

In this study, we analyse interdecadal variability in cyclone activity over northwestern Europe back to AD 1780 by combining information from eight storminess indices applied in an Eulerian framework.

We find pronounced interdecadal variability in cyclonic activity but no significant overall consistent long‐term trend. The major interdecadal‐scale variability common to all indices is in good agreement with geostrophic wind reconstructions for NE Atlantic and NW Europe, and with variations in the North Atlantic oscillation (NAO). Our results show that the reanalysis studies cover a time period chiefly coinciding with a marked, but not exceptional in our 225‐year perspective, positive variation in the regional cyclone activity that has more recently reversed. Because of the interdecadal variations, a near‐centennial time perspective is needed when analysing variations in extra‐tropical cyclone activity and the associated weather conditions over northwestern Europe.

Abstract Extra‐tropical cyclone frequency and intensity are currently under intense scrutiny because of the destruction recent windstorms have brought to Europe, and because they are a major meridional heat transport mechanism that may respond to differential latitudinal warming trends.
