Participants from the Southeast Asian region gathered online for the CORDEX SEA Outreach and Capacity Building Workshop 15-17 November 2021

The southeast Asia (SEA) domain is a very diverse region with different needs for climate information to address issues related to climate change. Therefore, we are pleased that we were able to reach so many people from different parts of the region with this workshop.

The workshop was an online event organized by the CORDEX SEA in collaboration with local organizers in Indonesia, Thailand and Malaysia and the CORDEX office at SMHI.

335 participants took part in the workshop via zoom, a majority from Indonesia but also from for instance Malaysia, the Philippines, Thailand and Vietnam and a few from outside the region. Since equity and equality, including gender balance, are important for CORDEX we are happy that the gender distribution was approximately equal. The workshop was also broadcasted via Youtube adding around 1000 persons that could view the live webinars and follow the discussions. This was thus a successful, large event that reached out to researchers, stakeholders and others.

Outreach CORDEX activities

The objectives for this workshop were to inform about:

  • and inspire new CORDEX activities in advancing the science and application of regional climate downscaling, especially in Asia
  • CORDEX Southeast Asia activities and progress in advancing the science and application of regional climate downscaling in through regional partnerships.
  • work carried out in several countries in Southeast Asia that used CORDEX Southeast Asia generated climate information in addressing issues related to climate change in the region
  • potential applications in the region of CORDEX Southeast Asia downscaled climate projections

SARCCIS and the progress on the 5 km simulations of CORDEX SEA highlighted during the workshop

The workshop highlighted the Southeast Asia Regional Climate Change Information System (SARCCIS), which serves as a one‑stop data center that freely disseminates high‑resolution, multi‑model and multi‑scenario simulated data, provides guidance on data usage and reliability, and provides training to users on how to access, analyze and interpret the data.

Another highlight was the presentations of the progress on the 5 km simulations of CORDEX SEA over a number of key regions in Southeast Asia. Furthermore, the workshop provided capacity building/development on data retrieval, application and analysis which is important for the future work within this region.

We are also pleased to hear that ministries and government agencies in Indonesia hope that high resolution downscaled data are expected to become a reference in climate-resilient national development. CORDEX-SEA data can be accessed freely by every stakeholder who needs it. The data will be used to bring together sectors, especially climate change adaptation and mitigation.

We hope that this workshop will be followed up with material/papers that discusses about data improvement for sector needs, and also special training to build the capacity of CORDEX -SEA members.

Online Paper-Writing Workshop on Regional Climate Modeling

thumbnail of Group Photo CORDEX CAM-SAM Follow-up Online Workshop October 2021

There is a need to foster coordination of downscaling initiatives for the South America and Central America and the Caribbean regions (SAM/CAM), and to pursue capacity-building activities in the region. CORDEX has, by supporting this online workshop, participated in the creation of new teams in regional climate research, consisting of PhD students and early career researchers in the region. These networks have not existed before and thus the capacity within the region has been increased.

This workshop on 5-6 October 2021 was a continuation of the Online Paper-Writing Workshop on Regional Climate Modeling that CORDEX Central America and South America organized in November and December 2020. It was an online activity, which resulted effective for the activities planned in the workshop. The dynamic of the discussions was organized in presentations of each group and general discussions during plenary sessions.

Collaboration and networking in the SAM/CAM region

The overall goal of the first workshop was to promote collaborative activities and networking in the SAM/CAM regions with focus on specific regional climate phenomena with the aim of enhancing the capacity of PhD students and early career researchers in designing a research topic on regional climate modeling and documenting/writing the scientific results.

Planning submission of papers

The objectives for this year’s workshop were to discuss the advances and shortcomings of the work and to plan the submission of the papers. The 42 participants, 13 of them females, came mostly from the South and Central American region.

Before the follow up workshop the organizer sent out a survey to get feedback from the first workshop, to find out how the work had proceeded since then, what drawbacks the groups had encountered and what was most urgent to discuss during the workshop. Despite some drawbacks and issues with finding time for the project due to other commitments, the participants were generally pleased with the first workshop and the progress of their continued collaboration.

Feedback on eight upcoming papers

The main outcomes of this follow-up activity are enhanced collaboration of young scientists, discussion of scientific questions and methods, increased dialogue amongst scientists within the CAM/SAM regional community and enhanced use of CORDEX SAM and CAM data to climate change and impact studies in both regions.

Other outcomes are divulgation of CORDEX activities through the presentation of the main results of the paper in the RAUGM (Unión Geofísica Mexicana) 2021, Mexico, analysis of scientific topics and documenting results in scientific papers.

All 8 groups presented their work to each other and the organizers during the two-day follow up workshop, giving each other feedback. In the plenary sessions the participants discussed general issues and the organizers gave suggestions.

The titles of the papers are:

Paper 1: Extreme indices of temperature and precipitation in South America: trends and intercomparison of regional climate models.

Paper 2: Daily extreme indices of precipitation and temperature over the CAM domain: Trends and intercomparison of the CORDEX-CORE regional climate models.

Paper 3: Heat waves and fire in Pantanal: historical and future perspectives from CORDEX.

Paper 4: Extreme Climate indices associated with soy and maize yields over Latin America-Part I. An observational and modeling perspective.

Paper 5: Twenty-first century drought and heatwave projections in the CORDEX models over tropical South America.

Paper 6: The relationship between strong Caribbean Low-Level Jet events and vertically integrated moisture flux convergence, and its underlying mechanism.

Paper 7: Assessment of the RegCM4-CORDEX performance in simulating cyclones affecting the western South America coast.

Paper 8: Early-stages structure of extratropical cyclones over South America: RCM added value and future changes in a warmer planet.


A wish for more training workshops in the future

Some groups are at a writing stage and some have finalized the draft and revised it. The organizers have helped out with the revision and shared their expertise. The general idea is that the papers will be ready for submission by the end of 2021.

Almost 90% of the participants would like to have more training workshops in the future according to the answers from the survey. They also proposed many good suggestions for topics for future workshops!
