Southern Scandinavian Storminess
Barring, L. and Fortuniak, K. 2009. Multi-indices analysis of southern Scandinavian storminess 1780-2005 and links to interdecadal variations in the NW Europe-North Sea region. International Journal of Climatology 29: 373-384.
The two Swedish scientists say their results show that former 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 [italics added]," noting that "because of the inter-decadal variations, a near-centennial time perspective is needed when analyzing variations in extra-tropical cyclone activity and the associated weather conditions over northwestern Europe."
In taking this more proper approach, the two researchers were rewarded by finding that (1) "there is no significant overall long-term trend common to all indices in cyclone activity in the North Atlantic and European region since the Dalton minimum," that (2) "the marked positive trend beginning around 1960 ended in the mid-1990s and has since then reversed," and that (3) "this positive trend was more an effect of a 20th-century minimum in cyclone activity around 1960, rather than extraordinary high values in [the] 1990s." Given such findings, there is no basis in this real-world data to suggest that the global warming of the late 20th century (now long-gone) produced any increase in storminess over northwest Europe.
