PRINCETON, N.J.– The vast loop of winds that drives climate and ocean behavior across the tropical Pacific has weakened by 3.5% since the mid-1800s, and it may weaken another 10% by 2100, according to ...

ABSTRACT Phenomena important for Atlantic climate variability include the Atlantic zonal equatorial mode, the tropical Atlantic meridional gradient mode, and the North Atlantic Oscillation (NAO).

An international team of scientists found that volcanic eruptions can cause the Pacific Walker Circulation to temporarily weaken, inducing El Niño-like conditions. The results provide important ...
