The findings improve scientists’ understanding of circulation changes that occur when hurricanes strengthen.

Since the start of the Industrial Revolution in 1750, the ocean has absorbed 20–30 percent of the new carbon dioxide emissions. That has mitigated rising atmospheric temperatures but increased ocean acidification. A new data set spanning 1750–2100 predicts future ocean chemistry.
Researchers long thought the Deep Western Boundary Current was the main pathway for deep water movement in the North Atlantic. A new study identifies another significant route, the Eastern Pathway east of the Mid-Atlantic Ridge.
Models have overestimated atmospheric levels of hydroxyl radicals, which break down methane. A new discovery shows that water vapor reduces sunlight's availability to make hydroxyl radicals, slowing methane’s atmospheric breakdown rate.
Drought is one of the costliest and deadliest climate-related disasters in the United States. NOAA’s National Integrated Drought Information System and the University of Nebraska Medical Center have led the development of the first comprehensive assessment of drought and health.
NIDIS , NOAA’s National Integrated Drought Information System, has launched a redesigned U.S. Drought Portal to better serve stakeholders, decisionmakers, the media, and the public. ...
The CPO-led National Integrated Drought Information System (NIDIS), has launched a redesigned U.S. Drought Portal to better serve stakeholders, decisionmakers, the media, and the public.
El Niño and La Niña affect weather in the United States, but the connection is a long chain of ocean-to-atmosphere links that climate models don’t always capture. New techniques may help scientists evaluate model accuracy.
NOAA-funded scientists found that warmer than normal ocean temperatures, rather than air temperatures, cause periods of rapid ice sheet calving known as Heinrich events. For decades, Heinrich events…
