Satellites recently captured plant life blooming in parts of the typically arid southern Sahara after storms moved there when they shouldn’t. It has also caused catastrophic flooding. And scientists say a world warming due to fossil fuel pollution is making both more likely. Rainfall north of the equator in Africa typically increases from July through September as the West African Monsoon kicks into gear.
The phenomenon is marked by an increase in stormy weather that erupts when moist, tropical air from near the equator meets hot, dry air from the northern portion of the continent. The focus for this stormy weather – known as the Intertropical Convergence Zone – shifts north of the equator in the Northern Hemisphere’s summer months. Much of it sags south of the equator during the
