Do Tropical Cyclone Outer Size Forecasts Improve Simultaneously With Intensity Forecasts?
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract The outer size of a tropical cyclone (TC) is important for predicting potential damage caused by the storm, yet improving the size forecast remains challenging. This study evaluates the TC intensity and outer size forecast performance of five numerical models from the National Oceanic and Atmospheric Administration (NOAA) based on 15 ...

Multi‐Year Ice Dynamics at Køge Bugt Central Glacier Controlled by Bed Topography
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Køge Bugt Central (KBC) is Greenland's fourth largest outlet glacier in terms of ice discharge. However, the drivers behind its substantial multi‐year variations in ice dynamics remain unknown. In this study, we use remotely sensed data sets of ice surface velocity, ice surface elevation, ice discharge, and terminus position, in combination ...

Tracking Hurricane‐Induced Water Storage Changes Using GRACE and GRACE‐FO Measurements
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Landfalling hurricanes pose significant hydrological risks, yet monitoring their terrestrial water storage (TWS) dynamics remains challenging. Here we employed a new technique that estimates daily regional gravity changes from orbital perturbation measurements of the Gravity Recovery and Climate Experiment and its follow‐on mission to ...
