ECMWF's main goal is to continuously improve medium-range forecast skill for the benefit of its Member and Co-operating States. In recent decades, predictive skill has steadily increased in the ECMWF Integrated Forecasting System (IFS) from the tropics to polar regions. Predictive skill in the Arctic remains lower, however, than in the northern hemisphere mid-latitudes (Figure 1). ECMWF's participation in the EU's Horizon 2020 project APPLICATE stimulated a concerted effort across ECMWF to examine in more detail the challenges that limit forecast skill in Arctic regions, and to identify ways to overcome them. It also fostered close interactions between ECMWF scientists and many colleagues in national meteorological services, universities and research institutes in the Member and Co-operating States and beyond, in particular at the Alfred Wegener Institute (Germany), Stockholm University (Sweden), MET Norway, the German National Meteorological Service (DWD), the UK Met Office, and Environment and Climate Change Canada (ECCC). Moreover, it supported ECMWF's contribution to the World Meteorological Organization's Year of Polar Prediction (YOPP).<br></p>
