Tracking Summer Greenland Blocking: The Upstream Pathway Shapes Historical Extremes and Future Change

International Journal of Climatology, EarlyView.
This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

A First Evaluation of ERA5-Land Reanalysis Temperature Product Over the Chinese Qilian Mountains

Frontiers in Earth Science, 2022
Reanalysis temperature products are important datasets for temperature estimates over high-elevation areas with few meteorological stations. In this study, surface 2 m air temperature data from 17 meteorological stations from 1979 to 2017 in the Qilian ...

Characterising City Scale Heat Climatology for Australian Climate Zones

International Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

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‐

Surface and Tropospheric Climatic Trends in the Galápagos Archipelago Based on the Galápagos Archipelago Refined Analysis Dataset

International Journal of Climatology, EarlyView.
The Galápagos Archipelago's near‐surface climate is primarily influenced by interannual El Niño‐Southern Oscillation variability, with no statistical evidence for long‐term trends in air temperature, humidity, or precipitation. While tropospheric warming and increased atmospheric stability are observed, these trends are largely decoupled from near ...

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.

Validation of ERA5 and ERA5-land reanalysis data for maximum and minimum temperatures in the Brazilian semiarid region

Theoretical and Applied Climatology
Abstract This study evaluates the performance of the ERA5 and ERA5-Land reanalysis datasets in representing daily maximum and minimum temperatures in the semi-arid region of northeastern Brazil—an area highly vulnerable due to its climatic and socioeconomic conditions.
