Translating October 1903 into a warmer world
October 1903 is the wettest month on record for the UK. A series of storms brought lots of rain across the country. If those same weather patterns occurred in a warmer world then they would bring more rain.
The top row of the animation below shows the reanalysis of October 1903 with mean sea level pressure contours (black) and rainfall (colours) in the real-world (left) and warmer world (right). The accumulated rainfall over the month is shown in the bottom row. The warmer world version brings more rain.
