Development of Next‐Generation Flood Inundation Maps: A Case Study in Kaohsiung City, Taiwan

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Flood inundation mapping has become a critical reference for flood risk management, particularly for determining insurance premiums and formulating mitigation strategies in rapidly urbanizing areas with high population density. With recent advancements in mapping technologies and high computing capacity, high‐resolution spatiotemporal datasets

Machine Learning Reveals Hidden Bias in ERA5 Cloud Heights Over Earth's Third Pole

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Accurate cloud base height (CBH) over the Tibetan Plateau—Earth's Third Pole—is essential for monsoon dynamics, glacial melt, and water security, yet ERA5 systematically underestimates it. Here, we present a two‐step machine learning framework to mitigate this hidden bias.

Can ERA5 Be Used to Study Mesoscale Convective System Climatological Characteristics?

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Mesoscale convective systems (MCSs) produce more than half of tropical rainfall and are central to the global hydrologic cycle. As the climate warms, environments favorable for MCSs may become more common; however, limited observational records hamper understanding of how MCSs respond to variations and changes in their environments.

A First Attempt at Reconstructing FengYun‐4B Stratified Precipitable Water Using GNSS

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Layer Precipitable Water (LPW) characterizes the vertical structure of atmospheric moisture and is essential for accurate weather forecasts. China's FY‐4B satellite delivers near‐real‐time LPW products, but is constrained by large uncertainties.

Low‐Frequency, Ultra‐Thin and Ultra‐Wideband Meta‐Absorber via Resonance Enhancement Harnessing Magnetic Material

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
This work proposes a novel strategy to integrate ultra‐wideband absorption and ultra‐thin thickness for low‐frequency P–S bands. A composite metamaterial absorber is verified experimentally by synergistically combining a customized three‐layer resonant structure with a top‐loaded magnetic material layer.
