Region 2:
Central America
Scientific highlights
This year we implemented a bias-corrected version of the statistical downscaling method of Navarro-Racines et al. (2020) at daily scale for 6 CMIP6 GCMs known to have the lower biases for the region according to Alzmaroui et al. (2021). We previously computed the 1 km monthly precipitation and temperature projections from 1979-2099 using the same method for all terrestrial Central America and Dominican Republic, but know we have the daily precipitation, maximum temperature and minimum temperature 1979-2099 projections for selected regions in Costa Rica.

Region 10:
Antarctica
Scientific highlights
Antarctic: The Antarctic ice shelves act as a safety band preventing ice to flow in the ocean and rising the sea level. However, recent studies showed they can rapidly collapse due to surface melt.
Model projections suggest large differences in future Antarctic surface melting even for similar greenhouse gas scenarios and warming rates, hence leading to large uncertainties in future sea level rise. Kittel et al. (2022) show that clouds containing a larger amount of liquid water led to stronger melt. Clouds could therefore be a major source of uncertainties in projections of sea level rise.

Region 11:
Arctic
Scientific highlights
Arctic: The Atlantic sector of the Arctic Ocean, including the high-Arctic archipelago of Svalbard is one of the fastest-warming locations on the planet. In addition to melting snow and ice which threatens a vulnerable ecosystem, thawing permafrost destabilizes slopes, coastlines, and man-made structure. For the latter, climate change impacts cultural heritage sites, e.g., the wooden houses in Ny-Ålesund and the coal cableway in Longyearbyen. To gain meaningful climate information on specific sites Langren et al. (2022) apply high-resolution (at 2.5 km horizontal resolution) regional climate modeling using HARMONIE Climate (HCLIM). They provide a multi-decadal convection-permitting climate projection dataset covering Svalbard for the years 1991-2060 following the SSP5-8.5 scenario. Projected future changes in the distributions, focusing on precipitation and snow, were quantified.

Region 12:
Mediterranean
(MED)
Scientific highlights
Med-CORDEX simulations
The phase 2 of Med-CORDEX was based on 5 modelling pillars (see
www.medcordex.eu/simulations-phase2.php ): the so-called “baseline runs” that gathers
evaluation and scenario simulations performed with fully-coupled Regional Climate System
Models (RCSMs), the 3 Med-CORDEX related FPS (FPS-convection, FPS-aerosol, FPS-airsea, see
specific annual reports) and the Free-Modelling Zone (see the activity list here). This phase
ended in December 2022.
The phase 3 of Med-CORDEX (see www.medcordex.eu/simulations-phase3.php ) is now
starting. The ”baseline runs” of this phase 3 are aligned with the new CORDEX-CMIP6 initiative
for the evaluation and scenario runs. They will be performed with fully-coupled Regional
Climate System Models (RCSMs), also called Regional Earth System Model (RESMs). Those
coupled models target to represent the high-resolution interactions of the various
components of the Mediterranean regional climate system. In Med-CORDEX phase 3, the
RCSMs will include at least the representation of the atmosphere, the land surfaces, the
surface hydrology (incl. rivers) and the Mediterranean Sea. Some modelling systems will also
include the Black Sea, the ocean biogeochemistry, the natural and anthropogenic aerosols
and/or the waves.
During the year 2022, the first actions of the Med-CORDEX phase 3 have been to: (1) list the
key challenges and define the overall strategy, (2) list the participating groups and models, (3)
design the simulation protocol for the evaluation (ERA5-driven) and the scenario (CMIP6-
driven) runs adapted to coupled RCMs, and (4) define the Data Requests for the ocean,
atmosphere, land surface and aerosol variables.
Med-CORDEX dissemination
Up to now (December 2022), the Med-CORDEX central database (phase 1 and phase 2 runs)
includes 124 datasets including Atmosphere, Land and Ocean variables, provided by 15
institutes, 8.4 To uploaded, 42 To downloaded by 305 users (find more information here
The Med-CORDEX simulations have been used over the past years in various assessment
reports, including the MedECC Mediterranean Assessment Report #1
(https://doi.org/10.5281/zenodo.7100601) and the RECO CROCC report (https://crocc.recooccitanie.org/) over the Occitanie region in France
In 2022, 5 new scientific articles have been published including two articles studying the
impact on climate change on the Mediterranean ocean biogeochemistry
To share the key documents of the Med-CORDEX phase 3 simulations (CORDEX-CMIP6), a
zenodo community open collection (https://zenodo.org/communities/medcordex/) has been
created

Scientific highlights
In 2022, the CORDEX-SEA team focused on three main activities: 1) preparing RegCM configurations for downscaling, 2) conducting CMIP6 downscaling experiments, and 3) further downscaling into 5 km resolution over some smaller domains.
1) Preparing RegCM configurations for downscaling:
Sensitivity tests have been conducted with RegCM4.9.5 to determine the best physical parameterization options. The study was conducted on a new domain of CORDEX-SEA (Domain 1: 89°E–147°E, 15°S–30°N), which is similar to the previous phases but extended northward (to 30°N instead of 27°N) to fully cover Myanmar.
49 experiments at 25 km resolution have been conducted using ERA5 as the ICBC conditions. The simulations ran for 6 years (2010–2015), where 2010 was used for spinning-up. The model outputs were compared to the APHRODITE datasets V1101 and V1809 for rainfall and 2m-temperature, respectively. We tested the sensitivity of the physical schemes with four cumulus schemes (Grell, MIT-Emanuel, Tiedtke, and Kain-Fristch), four PBL schemes (Holtslag, University of Washington (UW), GFS 2011, and MYJ), and three moisture schemes (Nogherotto/Tompkins, WSM5, SUBEX). Note that we did not use mixed cumulus schemes because previous experiments demonstrated that they created weird land-sea contrast in rainfall. For the ocean flux scheme, we used the default in RegCM, i.e. Zeng, since previous studies indicated that ocean flux schemes have minimal impact on rainfall and temperature. For the land surface scheme, we used the more advanced CLM4.5 scheme.
Based on the performance evaluation, Exp28 (Kain-Fritsch cumulus, UW PBL, SUBEX moisture) demonstrated advantages in simulating rainfall and temperature over Southeast Asia. We conducted an additional experiment with the schemes chosen in Exp28 for a larger domain extending eastward (Domain 2: 89°E–162°E, 15°S–30°N) to check the capability in terms of tropical cyclone simulation. The results showed no significant difference in tropical cyclone representation between the two domains. Therefore, we decided to use the Exp28 configuration with Domain 1 for the next step: downscaling CMIP6 products over the region.
2) Conducting CMIP6 downscaling experiments :
CMIP6 downscaling experiments have been started in some groups. We are sharing the downscaling tasks with our member groups. We are running the simulations using the following ICBC data (but not limited to): 1) ERA5, 2) MPI-ESM1, 3) CNRM-ESM2, 4) EC-EARTH3-Veg, and 5) NorESM2-MM. Additionally, the Meteorological Services of Malaysia is considering running another set of experiments using WRF forced by the same GCMs.
The runs are designed to cover the historical period 1970–2014, with projections for SSP3-7.0 , SSP1-2.6 , and SSP1-1.9 . Experiments with SSP2-4.5 and SSP5-8.5 may be conducted later if resources are available.
3) Future downscaling to 5km Resolution:
The Malaysian team has further downscaled the 25 km simulation into 5km resolution of Peninsular Malaysia domain. Currently the ERA5, and 1 GCM run have been completed, with the aim to further downscaling 3 GCMs.
