An Evaluation of Recent Global Geopotential Models for Strip Area Project in Turkey
Earth Sciences Research Journal, 2016 The aim of this study is to present the evaluations based on comparisons of geoid heights that are computed from several global geopotential models (GGMs) and the GNSS/levelling data. In this application framework, differences between geoid heights obtained by GGMs and GNSS/levelling were computed.

Distinct El Niño Flavors and SAM Variability Modulate Surface Melt Over the Ross Ice Shelf
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract Our study investigates how different flavors of El Niño, centered on the Eastern Pacific (EP) and Central Pacific (CP), and their interaction with the Southern Annular Mode (SAM) modulate surface melt events over the Ross Ice Shelf (RIS). Using satellite‐based melt observations, ERA5 reanalysis, high‐resolution regional model simulations, and ...

Subseasonal Tropical Convection Characteristics in the Energy Exascale Earth System Model Version 2
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract Accurate simulation of subseasonal tropical moist convection remains a key challenge for Earth system models. The difficulties stem from the reliance of cumulus cloud processes on model parameterizations and the need to represent the multiscale nature of interactions among clouds, radiation, moisture, circulation, and surface energy fluxes ...

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The Yangtze‐Huaihe River Basin (YHRB) has witnessed severe heatwaves in summer 2024, characterized by extremely high temperatures during both daytime and nighttime. Based on the daily maximum and minimum temperature data from the China Meteorological Administration, three dominant heatwave periods were identified over YHRB in summer 2024 ...

Entrainment‐Based Framework for Understanding Extratropical Moist Heat Extremes
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract In summer, the atmosphere over extratropical continents is close to moist convective neutrality, whereby near‐surface moist static energy, MSEs ${\text{MSE}}_{s}$, is tightly constrained by free‐tropospheric saturation moist static energy, MSE500∗ ${\text{MSE}}_{500}^{\ast }$.
