The Saharan dust that crosses the Atlantic and fertilizes the Amazon may be coming from the El Djouf region between Mauritania and Mali, which is farther west than previously thought.

A Whistle Here, There, and Everywhere on the Giant Planet
NASA’s Juno spacecraft is “hearing whistles” all over the place on Jupiter, a type of natural plasma waves called whistlers that are sometimes associated with atmospheric lightning.
Characteristics of Polar Sea Ice in Latest Climate Models
Sea ice area in CMIP6 is similar to previous versions while its sensitivity to external forcing is subtly different and closer to observations, but still not in step with global surface temperature.
All Hands on Deck to Catch Ion Cyclotron Waves
An international armada of orbiting satellites and ground VLF network join forces to form a “magnetosphere-ionosphere observatory” to size up electromagnetic ion cyclotron waves in the magnetosphere.
A New Perspective on a Classic Climate Conundrum
The Lagrangian method applied to tracking water transport between the Atlantic and Pacific basins reveals a larger contribution by mid-latitude westerly winds across Eurasia than previously thought.
Power Outage When the Aurora Throws a Curve Ball
Omega-band aurora carries fast propagating electric currents in the azimuthal direction, producing geomagnetically induced currents that can cause power outage on the ground beneath.
Globally Variable Water Content in the Mantle Transition Zone
Using electromagnetic waves originating in the ionosphere and magnetosphere, conductivity profiles reaching the deep upper mantle show surprising variability in water content.
Bridging the Gap Between Weather and Climate Predictions
A special collection on subseasonal-to-seasonal prediction presents the latest progress in filling the gap between short-term weather prediction and longer-term climate prediction.
Extremely High Carbon Return in Certain Volcanic Arcs
By comparing measured volcanic output with subducted carbon fluxes from drill cores, the Lesser Antilles subduction zone shows nearly complete slab carbon release at sub-arc depths.
Improving Atmospheric Forecasts with Machine Learning
An efficient, low-resolution machine learning model can usefully predict the global atmospheric state as much as 3 days out.
