A Nature study published on May 23 analyzes 35 years of precipitation data (1980–2015) to reveal how global climate patterns, or teleconnections, shape Morocco's rainfall during the wet season. By analyzing key climate patterns like the North Atlantic Oscillation (NAO), El Niño–Southern Oscillation (ENSO), East Atlantic Oscillation (EA), Mediterranean Oscillation (MO), and Western Mediterranean Oscillation (WeMO), the study reveals how each driver specifically shapes rainfall across Morocco's regions and seasons. Key findings suggest that the NAO and MO primarily influence winter rainfall, while the EA and WeMO have a stronger impact in spring. Other patterns, such as the Scandinavian (SCAND) and East Atlantic/Western Russia (EATL/WRUS) patterns, also shape regional precipitation. Notably, the influence of ENSO has strengthened since 2000, reflecting increased Pacific-Atlantic climate interactions and suggesting evolving global climate dynamics. «These findings clarify the seasonal and regional teleconnection dynamics governing precipitation in Morocco and highlight an emerging influence of Pacific climate variability in the twenty-first century», the authors conclude, adding that this improved understanding can «inform seasonal forecasting to support climate adaptation efforts in North Africa».
