A new deliverable report on severe weather event case studies evaluation and implications for monitoring within INTERACT is available. The report focus on forecasts of two types of extreme weather events: ArcticDefinitions of the Arctic vary according to environmental, geographical, political, cultural and scientific perspectives. Some scientists define the Arctic as areas having a high latitude, long winters, short, cool summers,... More heatwaves and early and late snow melt. The European Centre for Medium-Range Weather Forecasts (ECMWF) forecasts provided guidance of warmer than average temperatures up to 6-weeks in advance for both the 2018 European and 2020 Siberian heatwave. The potential role of land-atmosphere feedbacks in the predictability of these events is discussed. The forecasts of snow melt revealed a severe bias in the snow depth and snow extent which becomes worse at longer lead times. Using data from the Sodankylä field site, this bias is attributed to a low bias in the incident solar radiation. The report can be found here
