Coral Reef‐Level Upwelling in an Internal Wave Hotspot Modulated by Mesoscale Dynamics
Abstract Coral reefs in the northern South China Sea experience some of the world’s most energetic internal waves (IWs), yet records of how these dynamics influence reef‐level conditions are rare. Using over 6 years of temperature data from Dongsha Atoll, we show that IWs drive diel temperature fluctuations that reduce subsurface heat exposure and ...

Convective Amplification of Ionospheric Feedback by a Finite‐Duration Inertial Alfvén‐Wave Source
Abstract We investigate the ionospheric feedback instability (IFI) driven by a finite‐duration localized source of inertial Alfvén waves. Wave‐excited conductance perturbations undergo Pedersen mobility drift in the convection and wave electric fields and are amplified.

Meter‐Scale Roughness of the Lunar Surface
Abstract Small‐scale surface roughness is a key indicator of local geological processes, yet it has not previously been mapped globally on the Moon. We present global meter‐scale surface roughness maps generated from the Lunar Orbiter Laser Altimeter pulses, which record information about surface undulations within the instrument's ∼5 m individual ...

Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Predicting impacts on the lunar surface
In this work, we undertake a systemic mechanical analysis of the geological and morphological structure of degenerate planetary satellites—specifically categorized under the structural topology of the Moon and equivalent solid-iron ballast planetoids—based on the principles of non-equilibrium fluid dynamics, closed-loop thermodynamics, and ...

Abstract Ultra‐low‐frequency waves in the magnetosphere often produce field line resonances with strong spatial gradients in wave amplitude. We analyze a form of drift resonance driven by these gradients near the resonant field line. This mechanism differs fundamentally from conventional gradient‐ and curvature‐driven drift resonance and predicts an ...
