The impacts of multiple simultaneous climate variations
Climate variations—such as El Niño–La Niña (ENLN), the Madden–Julian Oscillation (MJO), and the Arctic Oscillation (AO)—have significant impacts on environmental conditions and operating environments around the globe. However, relatively little is known about how climate variations interact and alte...
