Global map showing SOFF countries to receive forecasts from ECMWF

ECMWF supports global initiative to provide more weather observations

ECMWF supports the UN’s Systematic Observations Financing Facility (SOFF) to widen the provision of weather observations in some countries, notably by agreeing to supply its forecasts to SOFF participants.
Non-hydrostatic vs hydrostatic forecast

The current forecasting equations are still valid near km-scale resolution

Recent investigations suggest that the equations ECMWF uses to forecast the global weather may not have to be updated to much more computationally demanding ones as long as the weather model’s horizontal grid spacing is no smaller than 2.8 km.

Looking for aspects of ECMWF’s weather model that can be improved

Rebecca Emerton is part of a team that tries to improve ECMWF’s weather model by looking for the causes of errors. She is also helping the EU’s Copernicus Climate Change Service, which is implemented by ECMWF, to draw up its yearly review of the climate.

How machine learning can support data assimilation

Data assimilation is the combination of the latest observations with a short-range forecast to obtain the best possible estimate of the current state of the Earth system. Machine learning can contribute to it by optimising the use of satellite observations.
