German TV interviews CORDEX co-chair about the release of information sheets based on EURO-CORDEX simulations

9 July 2021

The national German TV channel “ARD” contacted GERICS after hearing about the release of the  “Klimaausblicke” (Climate outlooks). In   the news item the reporter says that the data describing climate change in Germany has remained rather coarse in the past. This has now been changed by the publication of the analysis of climate data for each of the German counties by the Helmholtz-Zentrum Hereon / GERICS.

Altogether, 401   “Klimaausblicke” (Climate outlooks) can be downloaded for free to enable counties to prepare for the future.

Daniela Jacob says German counties now have access to detailed knowledge about possible future climate change, which needs to be considered for future planning.  No-one in Germany may say in the future: I didn’t know this.

The “Klimaausblicke” are based on 85 climate simulations (from the EURO-CORDEX community). Different scenarios, which depend on future climate mitigation, have been investigated,.

As an example, climate change information for different indices are given for the city of Karlsruhe located in South-Western Germany for RCP4.5 – representing a ‘middle’ emission concentration development.

Norbert Hacker, head of environment protection and work safety   in Karlsruhe, another guest on this news item talked about the consequences of present day climate change impacts and strategies, e.g., the dying of trees due to droughts and possible measures like watering trees in the city.

To sum up, it is mentioned that the “Klimaausblicke” are based on model simulations for this century carried out in a European effort. The spread shows that future climate change could be stronger or weaker dependent on our mitigation efforts.

After the release of “Klimaausblicke”, Daniela Jacob says that mitigating climate change is essential and that it is now obvious which consequences and related costs can be avoided by mitigating climate change.

The 42nd Session of the WCRP Joint Scientific Committee (JSC-42)

2 July 2021

Today will be the last day of the the 42nd Session of the WCRP Joint Scientific Committee (JSC-42). It has so far been a week with interesting discussions on further scientific, coordinative and communicative development.

The aim has been to, among others, approve and  plan for the new Lighthouse Activities,  the new ‘CORE Projects’ “Earth System Modelling and Observations” and “Regional Climate Information for Society (RIfS)” and of course discuss progress and plans for the already established Core Projects, Grand Challenges and other major activities.

Daniela Jacob, co-chair of CORDEX Science Advisory Team (SAT), on behalf of the CORDEX community held a presentation on CORDEX latest achievements, upcoming activities and scientific priorities as well as CORDEX contributions to RIfS.  Please see the CORDEX report and presentation at JSC-42 for more details.

For more information on JSC-42, please visit https://www.wcrp-climate.org/jsc42-about.

We look forward to further strengthen the CORDEX community involvement and to continued and increased cooperation and exchange across WCRP activities!

RAUMG 2021; submit abstracts

21 June 2021

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.

For further details visit: https://www.raugm.org.mx/ To register an abstract you will need to create an account: https://www.raugm.org.mx/resumenes/account/signin.php

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

25 May 2021

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

28 April 2021

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.
