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:

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.

A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin.

High background levels of ozone pollution make it hard for Las Vegas and other southwestern cities to meet US air quality standards in spring, two NOAA studies find.
But local pollution sources drive summer's high ozone days.

ABOUT US

Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
