Advancing our understanding of the Atlantic Meridional Overturning Circulation (AMOC)

A pause in the weakening of the AMOC since the early 2010s A recent study by scientists at AOML found that extensive weakening of the Atlantic Meridional Overturning Circulation (AMOC) occurred in the 2000s, but has paused since the early 2010s due to a tug-of-war between the natural and anthropogenic signals.  The AMOC is the […]

Scientists at AOML measure ocean’s crucial buffering against rising global carbon emissions 

Every year, scientists at AOML participate in the international effort led by the University of Exeter’s Global Systems Institute in developing the annual Global Carbon Budget Report, an assessment of global carbon emissions and the progress towards achieving the climate goals set by the 2016 Paris Agreement. The 2024 Global Carbon Budget Report now indicates […]

New NOAA research predicts an increase in active Atlantic hurricane seasons

Tropical cyclones are among the most deadly and costly natural disasters that affect the United States and many other countries each year. This has led the scientific community to prioritize improving tropical cyclone prediction and the understanding of how tropical cyclone activity has changed and will change in the future. In a new study published […]

New study finds a potential predictor for long-range US tornado forecasts

Tornadoes are among the deadliest and costliest natural disasters in the United States and are one of the hardest to predict. In December 2021, the most destructive winter tornado outbreak, known as the Quad-State Tornado Outbreak, caused 89 fatalities, 672 injuries, and at least $3.9 billion in property damages. Scientists at the University of Miami’s Cooperative Institute of Marine and Atmospheric Studies (CIMAS) and NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) investigated this outbreak and found that it occurred under an exceptionally strong and prolonged negative Pacific-North American (PNA) pattern, which created favorable conditions for tornado outbreaks.
