The Beaufort Sea, the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40 percent over the past two decades. How and where this water will flow into the Atlantic Ocean matters in local and global ocean conditions, including the Atlantic Meridional Overturning Circulation.

Today, NOAA and its partners are accelerating the advancement of numerical weather prediction by sharing a second application based on the Unified Forecasting System (UFS) framework with the ... ...

All tornadoes -- whether small or large -- originate from thunderstorms, but not all thunderstorms are the same. Different environments and situations create forecasting challenges. For instance, ... ...

Clouds have both cooling and warming effects on climate, so a climate model's ability to parse cloud effects can reduce uncertainty in future climate projections. A new study distinguishes between climate models with low and high climate sensitivity related to clouds and aerosols.

A new study in Nature Climate Change finds regional variations in snowpack melt as temperatures rise. The researchers conclude that, in the United States, snowpack in coastal regions and the south is most “at-risk” from climate change while snowpack in the northern interior of the country is less vulnerable.

Tornados, like most weather phenomena, are hard to predict more than several days in advance. By focusing on active tornado seasons that may be linked to climate signals, researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory have made a small but important step in seasonal tornado that shows promise in predicting active seasons up to two months in advance.

The results of a new high-resolution climate model indicate that global warming made the 2018 Cape Town “Day Zero” drought five to six times more likely than it would have been in the 19th century. Models project that, without significant reductions in greenhouse gas emissions, such extreme droughts in the Cape Town region will become more frequent, occurring every few years or almost every year by the end of the 21st century.
