Subduction of continental crust around the Gondwana supercontinent may explain the mantle Dupal anomaly of the southern hemisphere.
Southern Hemisphere
Diagnosing Neptune’s Chilly Summer
A pandemic project analyzing a trove of infrared images revealed an unexplained phenomenon taking place in Neptune’s atmosphere.
Current History: Exploring the Past of the Tasman Leakage
A new study sheds light on an important Pacific-to-Atlantic connecting current, including the global changes that led to its flowing that ushered in near-modern ocean circulation.
Is Earth’s Albedo Symmetric Between the Hemispheres?
The two hemispheres feature the same planetary albedo despite a larger land fraction in the north, because storms over the southern ocean are cloudier than their northern counterparts.
Southern Hemisphere Sediments Show Surprising Pliocene Cyclicity
New, high-resolution paleoclimate reconstructions with 100,000-year rhythms may offer insights into how Earth’s climate system operated during a time when the planet was warmer than it is today.
Estimating the Likelihood of Future Temperature Extremes
A prototype model allows scientists to investigate how wind eddies and other atmospheric phenomena may affect the prevalence of heat waves and cold snaps in the Southern Hemisphere.
Can We Crack the Climate Code of the Southern Polar Region?
The #GreatAntarcticClimateHack; La Jolla, California, 9–12 October 2017
Unraveling Hemispheric Ocean Nitrate Supply Pathways
Subsurface measurements of nitrogen and oxygen isotope ratios in nitrate reveal a predominantly southern hemisphere supply of nitrate to the equatorial Pacific.
Shifting Winds Write Their History on a New Zealand Lake Bed
A team of scientists finds a year-by-year record of climate history spanning the past 17,000 years at the bottom of a South Island lake.
Could Stratospheric Ozone Depletion Make Hadley Cells Expand?
Convection-driven Hadley cells are expanding poleward. Scientists now may have uncovered part of the reason why.
