Bias Correction of ERA5 Temperature Across Five Topoclimatic Clusters: A Comparative Evaluation of Four Methods

International Journal of Climatology, EarlyView.
ERA5 near‐surface temperature over South America exhibits systematic cold biases in daily maximum temperature and warm biases in daily minimum temperature. To address the continent's strong climatic and topographic heterogeneity, South America was partitioned into five topoclimatic clusters, and four bias‐correction approaches were evaluated. The Multi‐

Frequent, Intense and Prolonged Human‐Perceived Heat Waves Over the Arabian Peninsula in Recent Decades

International Journal of Climatology, EarlyView.
The spatial distribution of WBGT exhibits a widespread and significant warming trend across the Arabian Peninsula (AP), with, particularly, strong increases observed over the central and northern inland and eastern coastal regions of Saudi Arabia, Kuwait and Qatar, where trends exceed ~0.25°C decade−1.

Application of Ensemble Kalman Filter With Covariance Localization in Data Assimilation of Radiation Belt Electrons

Space Weather
Data assimilation aims to enhance the system state estimate by merging sparse and diverse measurements with physical models, while considering their individual uncertainties. As a highly promising data assimilation technique, Ensemble Kalman Filter (EnKF)

Greening and Divergent Stability Responses in Central Asian Mountain Grasslands Under the Grassland Ecological Compensation Policy of China

Land Degradation &Development, EarlyView.
ABSTRACT Mountain grasslands of Central Asia, recognized as a globally significant biodiversity hotspot and a vital pastoral resource, are presently experiencing profound transformations driven by climate change and evolving grazing practices. This study investigated the multidimensional dynamics of ecosystem stability in the Bayinbuluk grassland of ...

BARREL Observations of Microburst Events With a Slowly‐Varying Component

Geophysical Research Letters
Electron microburst precipitation has been shown to have significant potential for depletion of the outer radiation belt. We present observations from the Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) of six (five unique and one ...

Discriminating Arid Ecosystems and Tracking Desertification Dynamics: Evidence From Grain‐Size End‐Member in the Manas River Basin, Northern Tianshan Mountains

Land Degradation &Development, EarlyView.
ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing
