ECMWF's medium-range forecasts of near-surface weather parameters, such as 2-metre temperature and 10-metre wind speed, have become more skilful over the years, alongside improvements in upper-air scores. There are, however, persistent biases in these forecasts which have proved difficult to eliminate. In-depth investigations carried out at the Centre show that these biases are closely related to the coupling between the atmosphere and the land surface in the Integrated Forecasting System (IFS).
