Q&A: What do Arctic ice and Atlantic hurricanes have in common? Q&A: What do Arctic ice and Atlantic hurricanes have in common? New research examines the North Atlantic Oscillation and its influence on global weather The journal Nature Geoscience published a paper by Tom Delworth and his colleagues examining how a natural atmospheric force--the North Atlantic Oscillation--may be changing ocean currents in the North Atlantic. Among other impacts, the stronger ocean currents increase the amount of heat flowing toward polar areas, which could speed up Arctic ice melt and affect how hurricanes form. We asked Delworth a few questions about his study: Read more
Scientists deploy autonomous sailing vessels to study whales, fish and seals Scientists deploy autonomous sailing vessels to study whales, fish and seals Unmanned technologies open new frontier in ocean science NOAA Research and NOAA Fisheries have teamed up with academic and private sector partners to test innovative technologies that, if successful, will enable researchers to gather information on ocean conditions and marine species in remote areas of the ocean that are costly to reach and difficult to study.

New study: Sea ice loss likely no factor in cold Northern Hemisphere winters New study: Sea ice loss likely no factor in cold Northern Hemisphere winters The rapid loss of Arctic sea ice is a major driver of the warming trend sweeping across the Arctic in recent years, but melting sea ice is probably not behind recent cold winters in parts of Europe, Asia, and the United States, according to a new NOAA study.

Atmospheric Rivers: What are they and how does NOAA study them? 11Jan2023 Read more You may have heard of atmospheric rivers in the news lately due to the intense rainfall and flooding along the U.S. West Coast. These naturally occurring air currents can bring both severe disruption and great benefit through the heavy rain and mountain snows that contribute to regional water supply. NOAA studies atmospheric rivers to improve forecasting capabilities as well as to improve our understanding of atmospheric river impacts on communities and the physical environment. Read more
One facility makes a big contribution to Salt Lake’s winter brown cloud 25Jan2023 Read more The 2.4 million people who live along Utah’s Wasatch Front experience some of the most severe winter particulate matter air pollution in the nation. Now, analysis of measurements taken during NOAA research flights in 2017 indicates that emissions from a single source, a magnesium refinery, may be responsible for a significant fraction of the fine particles that form the dense winter brown clouds that hang over Salt Lake City.

When volcanoes roar: protecting the public and tracking long-term climate impacts 5Jan2023 Read more 2022 was a busy year for volcanic eruptions with Hawaii's Mauna Loa and Kilaeau erupting simultaneously, along with Mount Semeru, Indonesia and the Hunga undersea volcano in Tonga. While the United States Geological Survey is the primary agency that monitors volcanic activity in the United States, the National Oceanic and Atmospheric Administration (NOAA) oversees safety systems for tsunamis and other volcano-related threats, as well as studies the impact of volcanic gasses on our global climate.
