Geneva, Switzerland

The integration of the hydrological cycle as a key component of Earth System modeling and prediction, allows for a better understanding and simulation of interlinked processes in the atmosphere, cryosphere, hydrosphere, biosphere, and oceans. It is therefore critical to consider hydrological modelling and prediction developments in the broader context of various related Earth System components.

The Expert Team on Operational Hydrological Prediction Systems (ET-OHPS) under the Standing Committee on Data Processing for Applied Earth System Modelling and Prediction (SC‐ESMP) commenced its journey in September 2023. It will facilitate the advancement and linked development of hydrological prediction within the Earth System prediction framework by focusing on operational hydrological prediction systems. Please find the ToR of ET-OHPS here. 

To gain momentum and make progress and advancements, an in-person meeting is organized with the following objectives: 

  1. Develop an ET-OHPS workplan for the coming years to be submitted to INFCOM-3 (held in April 2024). 
  2. Define and discuss identified ET-OHPS priority topics.  
  3. Introduction of WMO ongoing activities and identifying linkages with and contributions from ET-OHPS. 
  4. Establishing a productive working relationship between the ET-OHPS members.  

The first in-person meeting with all members is scheduled to take place in Geneva, Switzerland, from November 28 to 30, 2023. This three-day event will have a hybrid format to accommodate participants unable to travel.
