Currents off the coast of northern Brazil can be used to study changes in the larger oceanic circulation pattern in the Atlantic, when variable winds in the regions are properly accounted for.
Research Spotlights
Research spotlights are plain-language summaries of recent articles published in AGU’s suite of 24 journals.
Electric "Tornadoes" in Space Drive Disturbances Down to Earth
New simulations show how shocks in space can trigger vortexes in Earth's magnetic field, causing magnetic disturbances that are detectable from the ground.
The Coming Blue Revolution
Managing water scarcity, one of the most pressing challenges society faces today, will require a novel conceptual framework to understand our place in the hydrologic cycle.
Model of Solar Cycle's Impact on Climate Gets Upgrade
A new model of how the Sun's 11-year cycle affects climate leads to slight changes in model results on atmospheric chemistry, but temperature and wind results are consistent with the previous model.
Mercury's Magnetosphere Model Gets Retro Makeover
New observations from Mercury revive a once-abandoned model for its magnetic field, resulting in a new profile that better fits the data.
Cloud Overlap Observations Put Simulations to the Test
Fine-scale simulations of cumulus cloud layers could help improve weather and climate models.
Aerosols May Play a Big Part in Atmospheric Absorption
A new study shows that aerosols have a strong impact on the reflectivity of the Earth's atmosphere, absorbing more solar radiation within the atmospheric layers than previously thought.
Alaskan Wildfires Influence Permafrost Recovery
Warming climate reduces permafrost's ability to recover following wildfires in Alaskan lowland forest.
Convection Cycles, Atmosphere, and Ocean Work Symbiotically
Scientists review studies of the tropical Madden-Julian Oscillation to better frame its role in air-sea interactions.
Forecast Versus Reality: High-Resolution Weather Prediction
Researchers test the High-Resolution Rapid Refresh model with real-life observational data to evaluate forecast accuracy.
