European storminess: late nineteenth century to present

摘要: Annual and seasonal statistics of local air pressure characteristics have already been used as proxies for storminess across Northern Europe. We present an update such Europe unprecedented analysis Central which together considerably extends the current knowledge European storminess. Calculations are completed three sets stations, located in North-Western, Results derived from spatial differences (geo- strophic winds) single station changes per 24 h support each other. Geostrophic winds' high percentiles (95th, 99th) were relatively during late nineteenth early twentieth century; after that they leveled off somewhat, to get larger again century. The decrease happens suddenly over several decades subsequent rise is most pronounced North-Western Europe, while slow steady Europe's storm climate has undergone significant throughout past 130 years comprises variations on a quasi- decadal timescale. Most recent feature average or calm conditions, supporting claims raised earlier studies with new evidence. Aside some dissimilarity, gen- eral agreement between investigated regions appears be prominent feature. capability NAO index explain varies space considered period.
