Workshop on surface process coupling and its interactions with the atmosphere

Bonn, Germany | 9-10 April 2025

Part of ECMWF's 50th anniversary celebrations

Overview

Surface interactions with the overlying atmosphere are essential for numerical weather predictions, from short-term near-surface weather predictions to enhanced predictability for slowly evolving timescales up to decades, and they become ever more important as resolution is increasing and as more processes are resolved. 

In this workshop, we will consider how to improve the representation of coupled processes to enhance future implementations of our global numerical weather prediction models between the ocean, waves, sea-ice, the land surface and the atmosphere. This will include coupling strategies and tools, conservation and consistency of the coupling, and differences in coupling strategies between physics-based and machine-learned models. 

We will split the time between presentations and breakout groups and prioritise discussions around future development targets. The expected outcomes from the meeting are a knowledge exchange between operational centres about current performance and future plans, and recommendations for future development work, including resolution, complexity and data driven solutions.
