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‐

Characterising Vento Norte Downslope Windstorms and Their Thermal Impacts in Southern Brazil

International Journal of Climatology, EarlyView.
Using 20 years of hourly INMET observations in Santa Maria (southern Brazil), we identify 189 Vento Norte (VNOR) downslope windstorms, ~72% in winter, marked by abrupt warming, drying and strong northerly gusts. Across five biometeorological indices (TEFW, TDI, THI, HDI, Humidex), VNOR hours consistently show significantly higher thermal discomfort ...

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

International Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.

ampycloud: an open-source algorithm to determine cloud base heights and sky coverage fractions from ceilometer data [PDF]

Atmospheric Measurement Techniques
Ceilometers are used routinely at aerodromes worldwide to derive the height and sky coverage fraction of cloud layers. This information, possibly combined with direct observations by human observers, contributes to the production of meteorological ...

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 ...

Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy

International Journal of Climatology, EarlyView.
This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...

Spatial and Temporal Patterns of Extreme Hourly Rainfall in the Hawaiian Islands

International Journal of Climatology, EarlyView.
The extreme rainfall trends in Hawaiʻi were revealed by hourly rainfall data: Across islands, Kauaʻi and Hawaiʻi Island had larger events at a return period. Annual maximum series of 15 gauges showed significant positive trends. While extreme rainfall trends show increases or decreases regionally, the trends varied with rainfall duration.

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.

A Zonal‐Meridional Projection Method for Quantifying Global Land‐Ocean Moisture Transport

International Journal of Climatology, EarlyView.
We present a physically consistent and computationally efficient method to quantify global coastal moisture transport by projecting vertically integrated moisture flux onto signed land–ocean boundary segments. The signed projection naturally distinguishes ocean‐to‐land inflow and land‐to‐ocean outflow without explicit directional classification ...

Assessing the socioeconomic footprint of tornado in Indonesia: A 15 year spatiotemporal impact analysis

Frontiers in Climate
Puting beliung, or small-scale tornadoes, pose significant threats to infrastructure and human lives in tropical island environments. This study analyzes the socioeconomic impacts of these extreme weather events in Indonesia over a 15-year period from ...
