Predictable Patterns of Seasonal Atmospheric River Variability Over North America during Winter
April 17, 2025 – Atmospheric rivers (ARs) are long and narrow atmospheric weather systems that carry large amounts of water vapor. ARs typically cover areas larger than 300,000 km2 and accompany significant precipitation changes over the U.S. They present both societal risks, such as flooding and extreme precipitation, and benefits – including contributions to water resources and snowpack.

What Are the Finger-like Clouds in the Hurricane Inner-core Region?
February 10, 2025 – The inner core region of hurricanes harbors complex dynamical features, including small-scale clouds characterized by finger-like appearances pointing toward the hurricane eye. These features have been frequently observed in intense hurricanes. However, many basic aspects of these features remain unknown, particularly regarding what controls their occurrence, location, and spatial distribution.

Effect of Regional Anthropogenic Aerosols on Tropical Cyclone Frequency of Occurrence
November 1, 2024 – Assessing the impact of anthropogenic climate changes on tropical cyclone activity is of notable scientific and public interest. Since 1980, human-made aerosol emissions have decreased in Europe and the U.S. but increased in China and India. This study used SPEAR, a climate model developed at GFDL, to explore how regional aerosol changes affect global tropical cyclones.

GFDL a Partner in NOAA’s Climate, Ecosystems, and Fisheries Initiative
November 20, 2024 – From warming waters and rising seas to melting sea ice and changing ocean pH, climate change is having major impacts on the nation’s marine and Great Lakes resources. In order to effectively prepare for and combat the effects of climate change, policymakers need robust historical simulations, as well as forecasts and projections, about how ocean and Great Lakes fisheries and ecosystems have changed and could change in the future. That’s where NOAA’s Climate, Ecosystems, and Fisheries Initiative (CEFI) comes in.
