Journal of Geophysical Research: Atmospheres, Volume 130, Issue 19, 16 October 2025.Abstract Convective heating and vertical motion are closely linked to each other and follow similar evolutionary paths over their convective life cycle. It has not yet been extensively explored, using observation, how such a collaborative evolution changes systematically from region to region over tropical oceans.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSpaceborne radar imaging is the key means to obtain the fine-resolution radar image of space targets. However, the nonuniform relative rotational motion caused by the high-speed orbital state leads to the degradation of the radar imaging performance.

The Effects of Ice Habit Models on Passive Microwave Snowfall Rate Retrievals
Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract This work examines the impact of ice habit models on snowfall rate (SFR) derived from space‐borne passive microwave observations. SFR retrieval is highly sensitive to ice habit assumptions. Comparisons of the SFRs based on Cloud Profiling Radar, ERA5, and National Oceanic and Atmospheric Administration Stage IV indicate that dense and sphere ...

Immediate Ice Stream and Shear Margin Response to Calving at Sermeq Kujalleq in Kangia, Greenland
Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.Abstract The sensitivity of Greenland outlet glaciers to short‐term flow disturbances lacks observations to be well constrained in numerical models. Specifically, sudden gigaton‐scale calving events regularly occurring at major Greenland outlet glaciers like Sermeq Kujalleq in Kangia (SKK; also known as Jakobshavn Isbræ) are known to perturb background
