12th Workshop on the Theory and Use of Regional Climate Models | (smr 4096) (25 August 2025

Administration

Description

An ICTP Hybrid meeting

Within the CORDEX international program’s mission, this workshop aims to enhance the capacity of scientists in developing nations to engage in advanced climate modeling research. By aligning with the IPCC’s initiative, it seeks to increase awareness among young climate scientists from these regions about opportunities to participate in global climate research and contribute to IPCC assessments.

The initiative’s significance lies in its focus on climate change readiness, addressing the heightened vulnerabilities of developing nations to challenges such as water scarcity, extreme weather events, and rising sea levels. It emphasizes the integration of climate change adaptation strategies into resource management frameworks to strengthen regional resilience against climate-related adversities.

The workshop will offer a blend of theoretical lectures and practical sessions covering the principles of regional climate modeling and the utilization of regional climate models (RCMs), with a focus on the ICTP RegCM5 system—a widely employed tool worldwide, particularly among scientists indeveloping nations. Additionally, this edition will introduce the emerging concept of AI-based climate emulators, which is increasingly gaining attention as a research topic within the climate science community.

Topics of the workshop include:

The theory of regional climate Earth system modeling
Regional modeling at the kilometer scale resolution (convection permitting)
Regional Earth system climate change simulations
Climate impact on hazards and extreme
Regional climate change attribution
The RegCM5 system
AI based regional climate emulator
