Objective

This workshop aims to advance actionable climate science by disseminating cutting-edge methodologies from Japan's SENTAN program while addressing key scientific challenges in projecting extreme weather events. A central goal is to foster dialogue between climate modelers and impact researchers to co-produce user-focused, actionable national scenarios. Ultimately, the workshop will build a lasting international network to support future collaborative research and the co-development of best practices in generating national-scale climate information.

The primary objectives of this workshop are to:

1. Share Cutting-Edge Methodologies: To present the advanced methodologies and latest scientific outputs from Japan's SENTAN program, particularly in high-resolution climate projections, dynamical and statistical downscaling, and ensemble analysis. This will be paired with facilitating a reciprocal exchange of knowledge and experience with leading international experts and national climate service providers.


2. Bridge the Gap between Data Producers and Users: To foster a dynamic dialogue between climate modelers who produce climate scenarios (the focus of SENTAN Area 3) and the researchers and practitioners who use this information for impact assessments and adaptation planning (the focus of SENTAN Area 4 and beyond). The goal is to understand user needs better and make climate information more "actionable."


3. Identify and Address Common Challenges: To collaboratively identify the key scientific and practical challenges in creating and applying national climate scenarios. This includes topics such as the robust quantification and communication of uncertainties, bias correction in regional models, and the projection of extreme weather events (e.g., typhoons, heavy rainfall) with greater fidelity.


4. Strengthen International Collaboration: To build and reinforce a global network of researchers and practitioners dedicated to advancing actionable climate science. The workshop aims to lay the groundwork for future joint research projects, data-sharing protocols, and the co-development of best practices for national-scale climate information.

Scope

The scope of the workshop will be centered on the scientific and practical aspects of developing and utilizing national-level climate scenarios for hazard and impact assessments, and adaptation. The discussions will cover the following thematic areas:

Theme 1 : Frontiers in National Climate Scenario Development

• High-Resolution Climate Modeling for atmosphere and ocean:
• Statistical Downscaling and Bias Correction:
• Ensemble Projections and Uncertainty Quantification:
• Projection of Extreme Events:

Theme 2: Advances in Climate Projections

• Future changes in extreme heat waves and their mechanisms
• Stationary linear precipitation system in a future climate
• Future changes in floods, water resources, storm surge, and extreme water levels
• Event attributions from a meteorological extreme event to a hydrological extreme one

Theme 3: Linking Projections to Hazard, Impacts, and Adaptation:

• Co-production of Climate Information:
• Developing Decision-Relevant Metrics:
• Application in Key Sectors:
• Data Infrastructure and Communication:

Participants and presentations

The two-day workshop will consist of keynote presentations, oral presentations (all invited), and an open poster presentation.

Additional information as appropriate

This workshop is strategically scheduled to take place on March 5-6, 2026, immediately preceding the CMIP6 Community Workshop 2026, which will be held from March 9-13 at the Kyoto International Conference Centre. This timing allows international experts traveling to Kyoto to attend both events, maximizing opportunities for collaboration. Furthermore, we have proposed a Town Hall meeting session in the CMIP6 Community Workshop 2026. This session will disseminate the key findings and outcomes from our workshop to the broader, highly relevant CMIP6 community, amplifying the impact of our event and strengthening the development of a global research network.
