The WMO Workshops on Operational Climate Prediction (OCP) started in 2015. They serve operational and research communities by reviewing progress in operational practices and understanding of climate prediction and sharing experience as we develop state-of-the-art operational climate prediction products from sub-seasonal to decadal time scales for WMO Members and partner organizations.

More information on the previous workshops can be found via these links: OCP-1OCP-2. The 3rd workshop aims to continue the dialogue between operational climate prediction centres and to strengthen interaction and partnerships between the operational and research communities, with particular emphasis on regional activities.

OCP-3 is to be held in person from 20 to 22 September 2022 in Lisbon, Portugal, hosted by the Instituto Português do Mar e da Atmosfera (IPMA).


Session topics

  • Current status of operational activities in sub-seasonal, seasonal and decadal time scales
  • Cascading climate prediction from global to regional to local scales
  • Research developments related to climate prediction on sub-seasonal to decadal timescales
  • Understanding user requirements
  • Tailoring of climate prediction products and information to meet user needs on sub-seasonal to decadal timescales
  • Use of ensemble approaches to effectively produce, deliver and communicate probabilistic sub-seasonal, seasonal and decadal climate predictions


Programme and Agenda

The programme and agenda of this workshop is available here (pdf file).

Key subjects/questions to be discussed during the workshop can be found in this document.

Posters are expected to be displayed in the workshop venue throughout the 3-day workshop. The recommended size for posters is A1 (841 x 594 mm or 33.1 x 23.4 inches) in landscape orientation. Each poster will be given a time slot of 3 minutes in plenary session to orally introduce the poster, please refer to the programme and agenda for more details. Participants presenting posters are invited to prepare one single slide for each poster, provided to the Secretariat in advance.

Working language of this workshop is English.

OCP-3 is open to the operational and research communities. There is no registration fee. WMO has limited resources to support the travel and per diem of invited participants. All other participants will need to cover their own travel costs.
