Blöschl et al (2017, ref 1) published a paper in Sciencethat purports to show flooding in S England occurs every year but only ever in January and that flooding is disconnected in time from extreme rainfall events via water storage in soils. The changing pattern with time is ascribed to man-made climate change and implications for insurance were highlighted by the Financial Times.
A simple analysis of actual UK flood records from the UK Met Office shows that floods actually occurred throughout the year and that these are always directly associated with extreme heavy rainfall of either convective or cyclonic origin. According to Blöschl et al, floods in Southern England occur only in January (Fig 1), but the Met Office records show no flooding in Southern England in January at all.
