Extreme Autumn and Winter Storms of the British Isles

To provide that longer-term context, Allan et al. (2009) extended the database of Alexander et al. back to 1920, almost doubling the length of the record, after which they reanalyzed the expanded dataset for the periods of boreal autumn (October, November, December) and winter (January, February, March).
Both databases exhibited peaks in storminess in the 1920s and 1990s, with boreal autumn storms being more numerous in the 1920s and winter storms being more numerous in the 1990s. In the figure below, therefore, we have plotted the total storm numbers for each decade; and as can be seen there, both the beginning and end decades of the record experienced nearly identical numbers of storms.

It should be clear from the results obtained by Allan et al. that the number of extreme storms impacting the British Isles over the last eight decades of the 20th century were not in any way related to the global warming of that period, which climate alarmists claim was unprecedented over the prior millennium or more.
