Save the date: 7th Workshop on Systematic Errors in Weather and Earth System Models
- Details
The Working Group on Numerical Experimentation (WGNE) will organise the 7th hybrid Workshop on Systematic Errors in Weather and Earth System Models, to be hosted by the Indian Institute of Tropical Meteorology (IITM) in Pune, India on 15th-19th February 2027.
Earth System Models (ESMs) are used to predict weather and climate from days to centuries ahead. Advances in computing and techniques such as machine learning have enabled more complex models and larger ensembles, supporting increasingly seamless weather–climate prediction systems. While these developments have improved forecast accuracy and relevance, significant challenges remain, including individual model errors as well as complex interactions within ESMs that generate systematic errors which are difficult to diagnose and reduce. Observational data are often insufficient to fully constrain models. Although major biases have been reduced, persistent and emerging errors highlight the need for continued model improvement.
The workshop aims to bring together a wide range of experts on simulating the Earth System including atmosphere, ocean, waves, land-surface, atmospheric composition, and associated disciplines to advance the understanding of systematic simulation errors at all timescales. A summary paper will document key findings and identify priority biases in ESMs.
