Projected Changes in CMIP6 MME for SSP5-8.5 Scenario: (a) Seasonal-mean 500 hPa geopotential height (m) difference between the climate change (2066–2100) and historical (1980–2014) periods (shading) and the climatological values (purple contours) averaged over the summer (JJA; left) and winter (DJF; right) seasons from the CMIP6 MME. Regions where 50% or less of the 10 CMIP6 models considered do not agree on the sign are masked in grey. (b–c) are as (a) but for the 200 hPa and 850 hPa wind speed (m s⁻¹), respectively. (d) and (e) scatterplots of the longitude and latitude of the center of the North African (0°–35° N; 15° W–30° E) and Arabian Peninsula (5°–35° N; 35°–60° E) subtropical anticyclones, respectively, for the summer season of each of the historical (blue; 1980–2014) and climate change (red; 2066–2100) years. The vertical and horizontal lines indicate the median value of the longitude and latitude, respectively, of the subtropical highs for each period. In both plots, some of the crosses, and the vertical lines, overlap with each other.
