Rapid Morphological Changes in the Intertidal Zone of the Ganges‐Brahmaputra Delta Revealed by SWOT Altimetry Mission

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Intertidal zones of the Ganges‐Brahmaputra (GB) delta are among the most active coastal environments worldwide, and quantifying their morphological evolution remains challenging due to rapid change and scarce in situ observations. This study presents a satellite‐based direct quantification of intertidal sediment volume change in the Meghna ...

A Delayed Return Stroke Driven by Channel Charge Accumulation

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Based on combined VHF interferometer and fast/slow antenna measurements, we document an abnormal bolt‐from‐the‐blue lightning flash, which included two strokes. There are four successive attempted dart leaders following the first return stroke. The last detected downward leader stopped advancing at approximately 94 m and decayed.
