Domain activties 2024

Scientific highlights

ESD: The University of Buenos Aires team has an active collaboration with the University of Cantabria
team working on deep-learning ESD over South of South America. The rapid growth of the application
of machine learning techniques as ESD techniques has motivated many research groups in South
America. CMIP6-ESD protocol offers an important opportunity to foster coordination and collaboration
within the SAM ESD community.
The generation of a regional bias-corrected dataset of climate impact indices in South America based
on CORDEX-CORE simulations is being constructed. This task is led by Rocio Balmaceda Huarte from
University of Buenos Aires and Ana Casanueva PI from University of Cantabria.
RCM: There is a concern in the community about the CMIP6-RCM simulations for the SAM domain.
The lack of resources, mainly storage capacity and post processing, is an obstacle for the SAM
community for conducting the simulations. The University of Sao Paulo in collaboration with the ICTP
plans to conduct CMIP6-RegCM5 simulations for the SAM domain.

Scientific highlights

- This year a publication on the results from statistically downscaled data for the Central American countries and Dominican Republic was published as a book chapter in an annual report from the Superior Council of the Central American countries (CSUCA in Spanish), part of the Central American Integration System (SICA in Spanish).
The article obtained the first place award of the respective call for papers. The downscaled data is originally in monthly time steps,but the daily data were also computed for selected subregions including the Yucatan peninsula and the Panama canal basins.
-With colleagues from CORDEX-CAM and SAM domains, Dr. Cavazos led a publication on the“Challenges for climate change adaptation in Latin American and the Caribbean” in Frontiers inClimate. The article was part of the WCRP/Concept Papers. In this article we mentioned the CORDEX activities in the region.
- Colleagues from CORDEX-CAM and SAM contributed to a publication “Regional climate change:consensus, discrepancies and way forward” which was part of the WCRP Concept Papers. Thearticle referenced the (general) CORDEX initiative.
-Two collaborative articles between scientists of CORDEX CAM and SAM were published thisyear as a result of the Online Paper Workshop on CORDEX held during the pandemia(Gramcianinov et al., 2024 and Portalanza et al., 2024).
- Several regional climate application articles were published using CORDEX simulations(droughts, viticulture, floods: Andrade-Gómez and Cavazos, 2024; Castillo et al., 2023;Hernandez Garcia et al., 2024; Hidalgo et al. 2024).
- We organized a special session at the annual meeting of the Mexican Geophysical Union (UGM) to support the new task force on oceans

In 2024, Stefan Rahimi and Callie Merissa Berman from the University of Wyoming collaborated with Shaukat Ali and Michelle to promote the dissemination of CORDEX activities in the Central Asia domain and support efforts to conduct climate projections for the region. This team has been holding regular online meetings to plan a workshop in Central Asia for 2025 and provide capacity-building opportunities for undergraduate, master's, and PhD students interested in climate modeling.
During these meetings, professors from Central Asia were also invited to discuss the challenges and opportunities related to regional climate downscaling initiatives.

Scientific highlights

Work led by the British Antarctic Survey (Gilbert et al., 2024) used a mini-ensemble of regional atmospheric models at 1 km resolution to investigate two case-studies (summer and winter cases) of an atmospheric river (AR) interacting with West Antarctica, and especially Thwaites Ice Shelf and Pine Island Ice Shelf. The models used were MetUM, Polar-WRF, and HCLIM. Estimates of snowfall associated with both events from all three model simulations compared well against observed snow height measurements over Thwaites Ice Shelf. Outputs from the simulations also show that the ARs may be associated with several millimeters of rain in both the summer and winter cases, although in the absence of in situ measurements of rainfall, this result cannot be directly verified. The occurrence of rain over snow-covered ice shelves are drastic, as they darken the surface and can amplify melting that in turn leads to more warming. The simulations suggest that rainfall during these events can fall directly as supercooled drizzle, but also that rainfall is concentrated around steep terrain due to the interaction of ARs with complex orography. This work therefore highlights that kilometer-scale models are useful tools to investigate the total precipitation amount and its partitioning into rain and snow over this globally important and climatically sensitive region, and the critical need for in situ observations of rainfall.

The Polar CORDEX community held another great meeting this year, and this time in Potsdam! There was a good mix of presentations on the latest scientific and modelling advances in the Arctic and Antarctic.
A highlight from this year’s meeting was the development of an ensemble of regional climate model (RCM) downscaling of two CMIP6 models over the Arctic CORDEX and Antarctic CORDEX domains.
Initial results on model performance shows great potential for the ensemble and it is expected that there will be more exciting results from this ensemble at next year’s meeting.
Work is now underway to publish the data on ESGF nodes. Other highlights from our meeting include progress on existing model intercomparison studies.
This includes a study on cloud-aerosol interactions and cloud microphysics in the Arctic that links with MOSAiC. More plans have been developed for future multi-model studies using the new ensembles.

Any other positive news or stories from your domain during the year

It was announced at this year’s annual meeting that Annette Rinke (AWI) will be resigning from her role as coordinator of Polar CORDEX. Annette has been a coordinator of Polar CORDEX since its inception in 2013, and has been pivotal in building a vibrant and strong Polar CORDEX community.
The community is very grateful to Annette for her tireless work coordinating and leading our downscaling activities.
At the meeting, we were also delighted to announce that Priscilla A. Mooney (NORCE, Bjerknes Centre) will join the coordination team and we look forward to continuing the success of Polar CORDEX with the new coordination team.
