Fig. 4: Rolling window analysis of precipitation probabilities and the NAO index in winter.
From: Increased persistence of warm and wet winter weather in recent decades in north-western Europe
Rolling window analysis with a window length of 30 years and ending years 1980–2020 of the probability of precipitation conditional on the highest quintile of the NAO index in winter for De Bilt, with 95% confidence intervals. 80th percentile of the winter NAO index of the respective window depicted in red.
