RAUMG 2021; submit abstracts

Dear colleagues,

We invite you to submit an abstract to our special session SE05: Regional climate modelling and CORDEX at the RAUGM 2021 (Annual Meeting of the Mexican Geophysical Union) to be held in Guadalajara, Jalisco, Mexico from October 31st to 5 November 2021. Our session will be mostly online, but it will be possible to attend in person if COVID-19 allows. Oral and poster presentations can be in Spanish or English.

Deadlines: July 31st for abstract registration and 4th September for pre-registration of participation.

Special Session SE05: Regional climate modelling and CORDEX / Sesión Especial SE05: Modelación climática regional y CORDEX

Regional models are a powerful tool to improve the knowledge of the physical, chemical and dynamical processes that regulate the weather and climate and their possible changes. Computational growth has favoured the development of a large number of global and regional models.

Multi-institutional projects for regional climate model simulations such as CORDEX (Coordinated Regional Downscaling Experiment) have produce regional climate models outputs at 50 and 25 km for several domains in the world, and in Europe at 10 km; CORDEX is currently developing the protocol for simulations at even finer spatial resolution forced with global models for a historical period and for future emission scenarios. The CORDEX information is available to the scientific community and it is relevant for regional process studies, for the evaluation of the possible impacts of climate change in different regions, and for decision-making and adaptation.

In this session, we are soliciting topics on:

1) Evaluation of regional models (dynamical or statistical) for different physical processes and impacts in various regions of the world including the CORDEX domains.
2) Studies of different physical processes relevant at regional scale under current and future conditions using regional models (dynamical, statistical, or hybrid downscaling).
3) Studies at local scale using convective permitting models.
4) VIA (vulnerability, impacts and adaptation) studies under climate change conditions.

2nd EURO-CORDEX workshop on prioritization of the use of SSPs

In the second EURO-CORDEX workshop, which took place April 29, 2021 the prioritization of SSPs for downscaling CMIP6 simulations was discussed. About 50 regional climate modellers gathered online.

It was concluded that low, medium and high scenarios are needed. A prioritization is needed for those who cannot afford to run all scenarios. While there is no consensus yet on the prioritization of the “worst-case” scenario SSP370 vs SSP585, there is consensus on the recommendation of downscaling the low SSP126 and the medium SSP245. It was agreed that EURO-CORDEX should follow the recommendations of the CORDEX-SAT, which will be published soon, for best consistency among the CORDEX communities.

Central/South America follow-up Online Paper-Writing Workshop

CORDEX Central America and South America are organizing a follow-up Online Paper-Writing Workshop on Regional Climate Modeling. The workshop will take place on May 3 and 5 at 17 UTC.

At the first online Paper Writing Workshop in November/December a number of collaboration groups consisting of students and early career researchers  were formed.  The groups choose a topic with focus on specific regional climate phenomena, outlined a work plan and time-line with the aim to submit a  paper with the scientific results. This follow-up workshop includes for instance update of status; project outline, data and methods and exchange of reviews between the groups.


WCRP CORDEX Report 2020

During 2020 a lot of activites, meetings, publications and workshops was held within the CORDEX community. It is hightlights from the domain reports, development of the CORDEX White Paper, progress within the Flagship Pilot Studies, First Order Draft for the CORDEX experimental design for dynamical downscaling of CMIP6 and much more:

The second order draft (SOD) of the CORDEX experiment design for dynamical downscaling of CMIP6

The First Order Draft (FOD) of the CORDEX experiment design (protocol hereafter) for dynamical downscaling of CMIP6 was shared with the CORDEX community in June 2020. We are very grateful to all who have read the protocol in detail and provided comments. The Second Order Draft (SOD) of the new CORDEX protocol is ready and we now want to share it with the CORDEX community for comments. In order to keep the process of developing the CORDEX protocol transparent and open for the community, the CORDEX Science Advisory Team (SAT) here provides responses to the comments on the FOD and how they have been addressed in the SOD.

Please find the SOD here and the CORDEX SAT responses to the FOD comments here.

You can leave your comments on the SOD in this Google form.

If you can´t access Google please let us know and we will send you an excel spreadsheet for your comments.

The deadline for comments is Friday 26th February.
