The study of extreme events in Europe found that through time the amount of extreme event increased in frequency. The magnitude of events also increased. The number of events recorded for the summer and winter suggest a dynamic interaction between the NAO, (North Atlantic Oscillation), the Siberian high, and the cooling and heating of the European continent. Overall, the summer precipitation and temperature were most diverse, with the most extreme events being recorded in this parameter. The overall general trend for the summer indicates that the summers can either be warmer or cooler depending on the flow of the hemispheric waves. The winter events, indicates that there was some variability, but generally the winters are becoming milder with time. The time series of the data runs from 1845 to 2003. Within this time period a cyclicity was noted of about 50 years, however due to the time series being relatively short it is uncertain if this is a true cycle.
