    Global changes in extreme events attributed to changes in mean climate and climate variability

    Extreme weather events are projected to change due to climate change, the risks to societies are therefore also changing. In a new study published in Communications Earth and Environment, Dr. Karin van der Wiel (KNMI) and Prof. Richard Bintanja (KNMI, Univ. Groningen) demonstrate that the increased occurrence of monthly extreme heat events is predominantly caused by a warming mean climate. In contrast, future changes in monthly heavy rainfall events depend to a considerable degree on changes in climate variability. Examining the origin of changes in extreme events, changing mean or changing variability, provides valuable insights into the processes driving these important climatic changes.

    A review of state-of-the-art machine learning methods for improving probabilistic weather forecasts

    KNMI scientists, Dr Maurice Schmeits and Dr Kirien Whan, have contributed to a review of the latest methods to improve weather forecasts using statistical and machine learning methods. The review was led by Dr St├ęphane Vannitsem from the Belgium Royal Meteorological Institute (RMI) and had contributions from scientists working on statistical post-processing at 11 national weather services (NWSs) in Europe, as well as Karlsruhe Institute of Technology, and the European Center for Medium-Range Weather Forecasts.

    Climate State Dependence of Arctic Precipitation Variability

    Arctic precipitation is projected to increase more rapidly than the global mean in warming climates. However, warming-induced changes in the variability of Arctic precipitation are largely unknown. Scientists from KNMI, in collaboration with the Institute for Marine and Atmospheric research Utrecht (Utrecht University), Energy and Sustainability Research Institute Groningen (University of Groningen), and the Water Systems and Global Change Group (Wageningen University & Research), have shown that the increase in precipitation variability towards warmer climates does not scale with the increase in mean precipitation. This is mainly attributed to the origin: while the increase in mean precipitation is largely attributed to the increase in surface evaporation, the increase in precipitation variability is attributed to variability in poleward moisture transport.
