Article’s title: « Des régions du Brésil en alerte face à une sécheresse de l’air historique »

The article discusses an unprecedented air dryness in several regions of Brazil, particularly in the northeastern states. This dryness is linked to a positive Indian Ocean Dipole (IOD) event, which has caused a decrease in rainfall and an increase in temperatures. Consequently, vegetation and water resources are severely affected, threatening agriculture and increasing the risk of fires. According to experts, this situation could worsen in the coming months due to the La Niña phenomenon.

Answer to the question: Several regions in Brazil, mainly in the northeast, are experiencing a historical air dryness caused by a positive Indian Ocean Dipole event, resulting in reduced rainfall, increased temperatures, and threats to agriculture and water resources.
