Figure subpanels
---------------------------------------------------
This figure has 43 subpanels (AR6 regions).

---------------------------------------------------
List of data provided
---------------------------------------------------
This dataset contains:

- regional averages over 43 AR6 regions of the changes in mean wind speed in percentage of the recent past value (median value and the 10th-90th percentile range of model ensemble values across each model ensemble) over land areas for the WGI reference AR6 regions (defined in Chapter 1) for:

- CMIP6 historical, ssp126 and ssp585

- CMIP5 and CORDEX historical, RCP2.6 and RCP8.5

- for the ‘recent past’ (1995-2014), mid-term (2041-2060) and long-term (2081-2100) time periods

- and for three global warming levels (defined relative to the preindustrial period 1850-1900): 1.5°C, 2°C and 4°C

Data provided in relation to Figure 12.SM.5

The regional averages of the changes in mean wind speed in percentage of the recent past value for all the subpanels (AR6 regions) are stored in three json files:

- CMIP5_sfcWind_diff-perc-baseline_AR6_regional_averages.json: data for the CMIP5 multi-model ensemble

- CMIP6_sfcWind_diff-perc-baseline_AR6_regional_averages.json: data for the CMIP6 multi-model ensemble

- CORDEX_sfcWind_diff-perc-baseline_AR6_regional_averages.json: data for the CORDEX multi-model ensemble

The content of the files is organized as follows:

- level 1 key:
- GWL: string: 1.5, 2, 3, 4
or
- name of the time slice: baseline or ${scenario}_${horizon}, with:
- ${scenario}: the scenario: ssp126 or ssp585 for CMIP6, rcp26 or rcp85 for CMIP5 and CORDEX
- ${horizon}: mid (mid-term) or far (long-term)
- level 2 keys: name of the AR6 region
- value: list with:
- first element: the multi-model ensemble 10th percentile (lower bounds of the vertical lines)
- second element: the multi-model ensemble median (the dots)
- third element: the multi-model ensemble 90th percentile (upper bounds of the vertical lines)

CMIP5 is the fifth phase of the Coupled Model Intercomparison Project.
CMIP6 is the sixth phase of the Coupled Model Intercomparison Project
CORDEX is The Coordinated Regional Downscaling Experiment from the WCRP.
SSP126 is the Shared Socioeconomic Pathway which represents the lower boundary of radiative forcing and development scenarios, consistent with RCP2.6.
SSP585 is the Shared Socioeconomic Pathway which represents the upper boundary of radiative forcing and development scenarios, consistent with RCP8.5.
RCP2.6 is the Representative Concentration Pathway for 2.6 Wm-2 global warming by 2100.
RCP8.5 is the Representative Concentration Pathway for 8.5 Wm-2 global warming by 2100.

Abstract

Regional projections for changes in mean wind speed for different scenarios, time horizons and global warming levels. The bar plots show projections of wind speed as percentage changes relative to the
recent past (1994–2015) for the mid-term (2041–2060) and long term (2081–2100), and for three global warming levels (defined relative to the pre-industrial period 1850–1900): 1.5°C (purple), 2°C (yellow) and 4°C (brown), using CMIP6 (darkest colours), CMIP5 (medium colours) and CORDEX (lightest colours) ensembles. RCP8.5/SSP5-8.5 is shown in red and RCP2.6/SSP1-2.6 in blue. The median (dots) and the 10th–90th percentile range of model ensemble values across each model ensemble and each time period are shown for the regional mean over land areas for the AR6 WGI Reference Regions (defined in Chapter 1). The CORDEX ensemble is missing in regions that are not fully covered by the CORDEX domain (EEU, ESB, RAR, RFE and WSB). See Technical Annex VI for details of indices. Further details on data sources and processing are available in the chapter data table (Table 12.SM.1).
