- The 40th Annual Meeting of the Working Group on Numerical Experimentation (WGNE) took place from 3 to 7 November 2025 in Beijing, China, and was hosted by the China Meteorological Administration (CMA).
Nov 03, 2025
to
Nov 07, 2025
(Europe/Berlin / UTC100)
Beijing, China
This milestone meeting will bring together WGNE members to review scientific progress, exchange ideas on ongoing and planned projects, and shape the group’s priorities for the coming year.
The agenda will include discussions on key areas such as:
-
Model development and evaluation
-
High resolution and physics parameterisations
-
AI/ML activities for prediction
Participants will assess the status of joint experiments, evaluate methodologies, and develop coordinated strategies to advance numerical experimentation and prediction capabilities.
This meeting is intended for WGNE members and affiliated projects, who are strongly encouraged to participate and actively contribute to the discussions and strategic planning.
