The next generation of supercomputers will break the exascale barrier. Soon we will have
systems capable of at least one quintillion (billion billion) floating-point operations per …

The vulnerability of social-ecological systems in sub-Saharan Africa (SSA) to climate
variability and change means that there is an urgent need to better integrate weather and …

This article presents coupled data assimilation (DA) activities at the European Centre for
Medium‐Range Weather Forecasts (ECMWF). Coupled DA is an essential component of the …

Environmental fluid mechanics underlies a wealth of natural, industrial, and, by extension,
