- Dust and Convection Model Biases – Team to investigate and provide feedback on model overestimation of surface temperature and convection during dust events, especially in Algeria.
- Low Cloud Representation in Winter – Task team to continue work on improving cloud and turbulence schemes, particularly for high latitude and winter conditions.
- Agricultural Forecast Verification – Team to compare model outputs with agricultural field data and consider the impact of non-representative meteorological stations (e.g., airports) on verification.
- Parameter Tuning for Turbulence – Plan to implement spatially adaptive parameter tuning for turbulence schemes to improve temperature forecasts, especially at northern latitudes.
- Snow Data Assimilation Improvements – Ongoing work to enhance snow data assimilation and its effect on temperature forecasts, with recent improvements noted and further changes planned for future IFS cycles at ECMWF.

5. Technical / Data Issues
Attendance in this breakout group turned out to be very limited. Discussions with the Meteo-France representative centred on an issue with downloading AIFS data from MARS; this problem was fixed soon after the meeting. There were also discussions with the Faeroese representative about the various challenges faced by a very small Met Service.
