Severity of Compound Precipitation and Temperature Extreme Events Over Africa at 1.5°C and 2°C Global Warming Levels

International Journal of Climatology, EarlyView.
Results indicate that, an increase in global warming level from 1.5°C to 2°C is likely to induce on the one hand a 3‐fold increase in the frequency of occurrence of dry and warm compound events, and on the other hand a 2‐fold increase in their duration, over West, Central, South‐West, and South‐East Africa, intensifying droughts through reduced ...

Seasonal Variability of Key Climate Parameters in the Mediterranean Region: Distinct Features From A Long‐Term (1940–2023) Analysis

International Journal of Climatology, EarlyView.
The intra‐annual variability of the Mediterranean climate does not include an even transition from winter to summer regime and vice versa. A detailed examination of the long‐term (84 years) mean intra‐annual variations of key parameters reveals remarkable and climatologically important peculiarities. ABSTRACT The intra‐annual variability of atmospheric
