An analysis of satellite data has revealed global patterns of extreme rainfall, which could lead to better forecasts and more accurate climate models…

For extreme rainfall events in Northern India (red diamond), the red lines show local weather patterns, and the blue lines show global patterns linking extreme rainfall events represented by the blue shapes. In particular, the blue shapes over Europe indicate that extreme rainfall in Northern India can be predicted from preceding events in Europe.Credit: Boers et al. 2019

The research, led by a team at Imperial College London and the Potsdam Institute for Climate Impact Research in Germany, could help better predict when and where extreme rainfall events will occur around the world. The insights can be used to test and improve global climate models, leading to better predictions.

The study additionally provides a ‘baseline’ for climate change studies. By knowing how the atmosphere behaves to create patterns of extreme rainfall events, scientists will be able to gain new insights into changes that may be caused by global warming….
