Historic Warm Periods Shed Light on Future Cyclones
Researchers look back in time to help understand our warmer future.
New Insights into Currents in Earth's Magnetic Field
Multisatellite missions give scientists a more complete view of the intense currents that bounce back and forth along our planet's magnetic field lines.
Deep Atlantic Conduit Boasts Longest Billow Train
Some 4000 meters below sea level, swirling patterns of more than 250 consecutive breaking waves up to 100 meters tall stretch through the Atlantic Ocean's Romanche Trench.
Global Atmospheric Model Simulates Fine Details of Gravity Waves
Whole-atmosphere general circulation model captures many aspects of mesoscale gravity wave structures—down to the tens of kilometers—and resulting temperatures and tides.
What Causes Sunspot Pairs?
Analysis of magnetic fields on the Sun's surface offers a new clue on why sunspots appear.
California's 2012–2014 Drought Unusual for Last Millennium
Soil moisture estimates, inferred from thousands of tree rings spanning the past 12 centuries, highlight the severity of the recent record-breaking drought.
Aquifers Spew More Pollution into Oceans Than Rivers
A new model makes a direct estimate of contaminants in submarine groundwater discharge.
Large-Scale Electric Currents May Flow Through Mercury’s Crust
NASA's MESSENGER spacecraft discovered electric currents in Mercury's magnetosphere directed toward and away from the planet. Do the currents reach the planet? If so, where do they go?
Unusual Echo Signal in Atmospheric E Layer
Metallic plasma layers in Earth's ionosphere interfere with radio communications and produce odd echo behavior at specific frequencies.
