A Two-Way Relationship Between the Atlantic and Pacific Oceans

Editors’ Highlight—A teleconnection between Atlantic sea surface temperature and eastern and central North Pacific tropical cyclones The relationship uncovered here between the Atlantic Meridional Mode (AMM) and hurricane activity in the eastern and central North Pacific Ocean is quite strong and the.... more

Deep Ocean Layers Continue to Heat Up

Kate Wheeling, Freelance Writer

From Research Spotlights—Researchers look at more than 3 decades of temperature trends in the deep ocean to understand the layers’ energy budgets. Earth’s energy budget, the delicate balance of incoming and outgoing energy that keeps the planet’s surface temperature relatively stable, is disrupted.... more

Initiation of Snowball Earth with volcanic sulfur aerosol emissions

Editors’ Highlight—This paper proposes that volcanic activity, specifically the injection of sulfate aerosols into the stratosphere, directly led to the Sturtian glaciation, the first Neoproterozoic global glaciation event. The authors test the plausibility of their hypothesis with three low-order atmospheric.... more

'The blob' of abnormal conditions boosted Western U.S. ozone levels

Joint Press Release—Washington, DC--An unusually warm patch of seawater off the U.S. West Coast in late 2014 and 2015, nicknamed “the blob,” had cascading effects up and down the coast. Its sphere of influence was centered on the marine environment, but extended to weather on land. A new study shows.... more

Researchers catch extreme waves with higher resolution modeling

Blog—Surfers aren’t the only people trying to catch big waves. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) are trying to do so, too, at least in wave climate forecasts. Using decades of global climate data generated at a spatial resolution of about 25.... more Earth & Space Science News

First Results from NASA's Magnetospheric Multiscale (MMS) Mission

The Magnetospheric Multiscale (MMS) mission has been performing particle and electromagnetic field measurements in the near-Earth environment since its launch in March 2015. Thanks to data with unprecedented time resolution on four identical spacecraft in a close tetrahedron configuration (down to 10 km), MMS science goals are to probe and understand the electron-scale physics involved in the magnetic reconnection process. This collection provides a selection of key results obtained during the first phase of the mission at the dayside magnetopause. It includes new observations of the geometry and variability of the reconnection process, the detailed dynamics of particles, fields and waves in the vicinity of the reconnection region, the observation of small-scale signatures at current sheets formed in the magnetosheath, in Kevlin-Helmholtz vortices, or flux transfer events, as well as other small-scale features which are by-products of magnetic reconnection or not. These results open a new window for our understanding of magnetic reconnection in space, with direct and numerous implications for astrophysical and laboratory plasmas.
