Resultant Force on Grains of a Real Sand Dune: How to Measure It?

open access: yesGeophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract Barchan dunes usually appear under the action of one‐directional fluid flows, being found on Earth, Mars, and other celestial bodies; however, although ubiquitous in nature, understanding dune dynamics at the grain scale is challenging due to the vast number of grains involved.

ARTEMIS Observations of Electron Cyclotron Harmonic Waves in the Lunar Plasma Environment

open access: yesGeophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract We report Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon's Interaction with the Sun (ARTEMIS) observations of electron cyclotron harmonic (ECH) emissions in the lunar plasma environment. ECH emissions are correlated with electron loss‐cone distributions and electron beams during periods of magnetic connection to the ...

The Mechanism of Interhemispheric Coupling Revealed by a Gravity Wave‐Permitting General Circulation Model

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract Interhemispheric coupling (IHC) is the positive correlation between temperatures in the polar winter stratosphere and the polar summer upper mesosphere and the lower thermosphere. Over the past two decades, several mechanisms have been proposed to explain the IHC.
