First Observation of Sawtooth‐Like Undulations in Afternoon Detached Auroral Arcs Modulated by Surface Waves at the Plasmaspheric Plume Boundary

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract The afternoon detached auroral arc is an important phenomenon in the subauroral region, reflecting coupling processes between the Earth's magnetosphere and ionosphere. Previous studies have not identified fine‐scale structures in such arcs, leaving the dynamics underlying their formation poorly understood.

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.

Enhanced Extreme Precipitation Simulation in China Using NCAR CESM Based on a Realistic Remotely‐Sensed Time Series of Annual Land Cover and Land Use Data From 1982 to 2013

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Accurate simulation of climate extremes is critical for climate mitigation and adaptation. The role of land cover and land use change (LCLUC) on climate extremes has been well documented. Yet, current modeling studies can barely capture how LCLU evolves in the real world, limiting their ability to reliably simulate climate extremes. This study

Evaluating the Biases in Indian Summer Monsoon Rainfall Simulation Using the Global Storm Resolving Models: An Assessment of the DYAMOND Models

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study evaluated the performance of various global storm‐resolving models (GSRMs) in simulating the Indian Summer Monsoon (ISM), highlighting the limitations of current global kilometer‐scale models in accurately representing precipitation patterns over the Indian subcontinent.

Contemporaneous Appearances of Auroral Spiral and Transpolar Arc: Polar UVI Observations and Global MHD Simulations

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract A local vortex‐structured aurora and a large‐scale transpolar arc (TPA) were contemporaneously observed by the Polar ultraviolet imager (UVI) during the late recovery phase of a substorm, and the interplanetary magnetic field (IMF) BY and BZ were negative and negative‐to‐positive. The TPA grew along the dawnside auroral oval from the nightside
