Scientific highlights at the Polar CORDEX meeting

The Polar CORDEX meeting was held online 5-7 October 2020 with the aim to present updates by the Arctic and Antarctic CORDEX community and discuss future projects/collaborations. The meeting had a very good gender balance with 12 women and 14 men. The participants were mainly from Europe and North America, but there were also participants from India, Chile, Argentina and Japan.

Arctic and Antarctic scientific highlights

The Arctic CORDEX session had seven science presentations, which focused on new modelling efforts, key drivers of Arctic cyclones, simulations of future climate change, and teleconnections. One of the highlights was an improvement in simulation of temperature at the snow/ice surface in the CCLM model.

The four science presentations in the Antarctic CORDEX session focused on new modelling efforts, improved understanding of clouds, and efforts to model surface mass balance. One of the highlights was details of a new model to Antarctic CORDEX, the polar region climate model NHM-SMAP (Japan Meteorological Agency).

Polar CORDEX: Next Steps

The ‘Polar CORDEX: Next Steps’ session had both presentations and discussions. One of the science highlights was the presentations on how the Polar CORDEX simulations will be used for the IPCC Interactive Atlas. The discussions identified key ways for the Polar CORDEX to collaborate in the future, especially involving both the MOSAiC and the YOPP supersite observations. Furthermore, the benefit of a closer link to the satellite community e.g. via the ESA Climate Change Initiative (CCI) was discussed. An important outcome was the agreement to increase the size of the Antarctic CORDEX domain to encompass more of the Southern Ocean, so that output from the model simulations could be used more for impact studies (e.g. forcing sea-ice and ocean models).

There was also a recognition that undertaking studies involving multiple Polar CORDEX models was highly beneficial.

A successful first online Polar Meeting

This was the first time a Polar Meeting was held online but the overall feedback was positive. By keeping the individual sessions short (2 hours), spread over 3 days (one session per day), and limiting each presentation to 15 minutes everything worked well. Also, separating the sessions out into ‘Arctic CORDEX’, ‘Antarctic CORDEX’, and ‘Polar CORDEX, Next Steps’ meant that each session was well focused. The material presented was excellent, and each presenter was disciplined and stuck to their allocated time. Also, the Discussion/Next Steps worked well as it was emphasized the strong collaboration that Polar CORDEX is built on, and discussed some very timely projects such as how Polar CORDEX contributes to IPCC AR6 Regional Atlas and could contribute to MOSAiC and YOPP (Year of Polar Prediction) supersite intercomparison.

Next meeting in autumn 2021

The next Polar CORDEX meeting is planned to be held in autumn 2021 and hopefully a in person meeting will be possible at that time.

Central America and South America Online Paper-Writing Workshop on Regional Climate Modeling

Central America and South America are organizing an online Paper-Writing Workshop on Regional Climate Modeling. The workshop will be held on the 24-25 November  and 8-9 December 2020.

Objectives of the Workshop:

In face of the 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, the overall goal of this activity is to promote collaborative activities and networking in the SAM/CAM regions with focus on specific regional climate phenomena. In this context, a virtual workshop on paper-writing is proposed 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.

Collaboration between CORDEX and MAIRS-FE

A joint meeting on further collaboration between CORDEX and MAIRS-FE
will be held online 9-10 November 2020. This meeting will be for invited partners and stakeholders only.
More information will be published soon.

Regional climate change projections: Climate change analysis using CORDEX regional climate models over South Asia

The training on Regional climate change projections: Climate change analysis using CORDEX regional climate models over South Asia will be held 12-14 and 19-21 October 2020. The training is organized by CORDEX South Asia and is for invited participants. It was initially planned to be held in Kathmandu, Nepal, but will now be an online training. Hopefully it will be possible to hold an in-person training during 2021.
