Workshops and other activities

This year we reduced the number of events due to the COVID-19 pandemia, only a couple of them were organized as online meetings. We supported many requests of CORDEX-CAM data from students and scientists of various countries (Mexico, Guatemala, Italy, Portugal, and the United States)

We participated ONLINE in a special session at the Annual Meeting of the Mexican Geophysical Union (RAUGM 2020) on 3 November 2020. We have been organizing this session since 2014:

SE13: Regional Climate Modelling and CORDEX / Modelación climática regional y CORDEX. Organized by Tereza Cavazos (CICESE), Gabriela Colorado-Ruiz (CICESE), Rosa B. Luna-Nino (CICESE), and José Abraham Torres-Alavez (ICTP).

In November and December we organized an online paper-writing workshop that was supposed to be in Sao Paulo. At the end, we did it online in two parts (November 24-25 & December 8-9, 2020) and it worked pretty well with 45 young students and scientists from different countries. The objectives were to foster the collaboration, capacity building, and the possible submission of several papers on CORDEX-CAM-SAM data next year. There will be a report of this event to CORDEX:

Region 5:
Africa

Globe showing the CORDEX domain of Africa

Scientific highlights

Academic publications

Lack of funding and the impact of COVID19 meant it was not possible to run the anticipated workshops planned for 2020. However, at least eight papers were produced during 2020 by CORDEX-Africa participants. There is continued collaboration between the climate science and VIA groups.

Rotating SAT member

Dr Chris Lennard has completed his term on the SAT and Wilfried Pokam has been selected to replace him. Chris will assume the position as a POC for the region.

FPS

Two Africa-led FPSs have been received and on review both have been returned to the proposers to address review comments. If review comments are accounted for the FPSs will be accepted. These are “Simulating role of aerosols on the past climate change attribution and future projection in West Africa” and “Rainfall responses to climate change in a convective-permitting model over Western Cape (HighResWC)”. Work in existing FPSs is ongoing with good progress. The FPS titled “Coupled regional modelling of land-atmosphere-ocean interactions over western-southern Africa under climate change“ has not sustained funding to run to completion and has stalled because of this. Further efforts will be made to source funding in 2020 that would facilitate completion of the FPS. In the ELVIS FPS CORDEX-Africa affiliates are involved in the analysis of the simulations being performed over the region.

IPCC

Several CORDEX-Africa affiliates are involved as Lead Authors and Contributing Authors in the IPCC Sixth Assessment Report (AR6). Lead Authors are involved in WG1 Chapters 8, 10, 11, 12 and the Atlas and also in WG2 Chapter 9 (Africa).

CORDEX-CORE data

Data from the CORDEX-Core simulations have been downloaded at CSAG and can be distributed on request (and receipt of external hard drives) to CORDEX-Africa participants as well as other interested persons.

Other news from CCAM group:

Over the past 9 months UQ have used 2020 version of CCAM with 35 vertical levels and C288 (~36km global) stretched to ~10 km over whole of Australia and completed 9 experiments with RCP85 for Access1.3 x 2,  Access1-0 x 1, CanESm2 x 2, CESM-CAM5, MPI-EMS-LR x 1 and NorESM1-M x 1 for 1970-2099 period. Datat was saved every 3 hrs interval. x2 means experiment was run in both atmospheric only and coupled ocean CCAM model.

Data for rnd24, tmean, tmin and tmax were extracted from raw model output at 5km AWAP grid and was bias corrected using non-parametric BC method. Subsequently heatwaves, extreme precipitation and rainfall indices, SPI drought were derived from above simulations at 5 km over Australia. At 10 km FFDI, Haines index, mean climate and TC detection were completed.

Preparation for CMIP6 are progressing, UQ have converted matlab scripts to python for SST/sea ice BC and testing trying to have consistent SST/sea ice fields. Downloaded all available SSTs and sea ice from all SSPs for CMIP6 and will product SST/sea ice for CCAM. Hope to run CMIP6 soon.  Marcus Thatcher (CSIRO) has provided ERA5 data for CCAM run plan to run CMIP6 version of CCAM with ERA5.

TERN has published two datasets.

Scientific highlights

We had four science presentation in the Antarctic CORDEX session of the Polar CORDEX workshop, which 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).

The ‘Polar CORDEX: Next Steps’ session had four presentations, as well as a period for discussion. One of the science highlights of this was two presentations on how the Polar CORDEX simulations will be used for the IPCC Interactive Atlas. Additionally, the period for discussion was valuable as it identified key ways that the Polar CORDEX could 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. A further important outcome was an 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).

Scientific highlights

Under SEACLID/CORDEX Southeast Asia, Tangang et al. (2020) reported 11 GCMs have been downscaled using 7 RCMs at 25 km. A regional data portal called the Southeast Asia Regional Climate Change Information System (SARCCIS) has also been established as an ESGF data node. Generally, the projection calling for increase rainfall over Indo-China during DJF but decrease rainfall in Maritime Continent during JJA. Large biases and inter-model variations tended to be over archipelago regions as 25 km may not be sufficient. On-going simulations focused on further downscaling of a number of subdomains at 5 km resolution.

Another initiative under CORDEX-CORE managed downscale 3 GCMs using 2 RCMs at 25 km resolution.
