A Convolutional Neural Network for the Detection of Gravity Waves in Satellite Observations and Numerical Simulations

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Comparisons between observed and model‐resolved gravity waves (GWs) are crucial for evaluating general circulation model (GCM) simulation accuracy and understanding wave characteristics. However, observational noise often obscures waves, complicating such comparisons.

Absolute geopotential height system for Ethiopia

, 2010
This study used airborne gravity data, the 2008 Earth Gravity Model (EGM08) and Shuttle Radar Topographic Mission (SRTM) digital elevation data in a ‘Remove-Compute-Restore’ process to determine absolute vertical reference system for Ethiopia. This gives a geopotential height at any isolated field point where there is a Global Navigation Satellite ...

Anticyclone Driven Heat Waves Intensify Beijing's Urban Boundary‐Layer Turbulence

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Heat waves (HWs), intensifying under climate change, critically modulate planetary boundary‐layer (PBL) turbulence through poorly constrained mechanisms. Leveraging unique radar wind profiler network measurements across three Beijing during the record‐breaking 2023 summer (16 HW days), we quantify the turbulence dissipation rate (ε) variations

Intensified Interannual Variability of Arctic Sea Ice Modulated by Strengthened North Atlantic Oscillation Leads to an Enhanced Impact on Asian Winter Cold Extremes

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Arctic sea ice concentration (SIC) exhibits significant interannual variability despite a persistent decline due to global warming. This variability is influenced by atmospheric internal variability such as the North Atlantic Oscillation (NAO) and the Pacific‐North American pattern (PNA).
