Extreme rainfall in southern China in April 2024 and its potential link to weather events across south Asia

Weather, EarlyView.
This study documents the unseasonal and prolonged heavy rain events which occurred in southern China during April 2024. In this series of extreme rainfall events, Guangdong province recorded extreme rainfall exceeding 6‐sigma of climatology, with eleven cities reporting record‐breaking rainfall.

From scores to causality and confidence: operational acceptance of AI weather forecasts

Weather, EarlyView.
This paper argues that the operational value of machine learning weather prediction (MLWP) cannot be assessed through verification skill alone. Instead, acceptance depends on support for the core functions of operational meteorology: understanding, translating and communicating. Current MLWP systems show strong performance but lack the interpretability,

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

Insect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.

Comparing Remotely Sensed and Weather Station Measured Rainfall Data for Flood Prediction in KwaZulu Natal, South Africa

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Extreme rainfall events frequently trigger flash floods, which cause widespread damage to ecosystems, infrastructure, and livelihoods. Accurate rainfall estimation is therefore essential for flood modeling and early warning systems. This study assessed the performance of the Tropical Rainfall Measuring Mission (TRMM) and the Global ...

Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5891-5918, November 2026.
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

Coral Reef‐Level Upwelling in an Internal Wave Hotspot Modulated by Mesoscale Dynamics

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
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 ...

Quantifying Nighttime Gravity Wave‐Driven Mesosphere‐Ionosphere Coupling Over CONUS Using NASA AWE Radiance and GNSS TEC Observations

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We present the first coordinated study of nighttime mesosphere‐ionosphere coupling over the continental United States (CONUS) from January through November 2024 using NASA Atmospheric Waves Experiment (AWE) airglow measurements near 87 km and GNSS Total Electron Content observations near 300 km.

Fractal Dimension of Shallow Cumulus Cloud Boundaries Beyond Bulk Fractal Scaling

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Cloud boundaries reflect turbulent mixing and cloud–environment interactions, but their geometric complexity remains poorly quantified. Here, we investigate the complexity of shallow cumulus cloud edge using two fractal approaches: the bulk area–perimeter method and the individual‐cloud box‐counting method.

Morphological Characteristics of Tropical Precipitation Features Producing Extreme Instantaneous Rain Rates in GPM and DYAMOND Global Storm Resolving Models

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The influence of the spatial organization of tropical convection on the production of extreme instantaneous localized tropical rain rates remains poorly constrained, both in observations and in models. Using retrievals from the Ku‐band radar onboard the GPM satellite, we identify tropical precipitation features (PFs) and quantify their ...

Boundary‐Aware Separation of Vortical and Wavy Motions in the Ocean

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract With the recent popularity of the tide‐resolving and submesoscale‐admitting numerical simulations, there is an increasing interest in separating vortical and wavy motions in the ocean. The recently‐proposed dynamics‐based decomposition exploits the relative magnitude of the relative vorticity and horizontal divergence in Fourier space and ...
