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 ...

Sensitivity of Blocks and Cyclones in ERA5 to Spatial Resolution and Definition

Geophysical Research Letters, 2020
AbstractERA5, the fifth‐generation reanalysis of the European Center for Medium‐Range Weather Forecasts, provides long time series of atmospheric fields at high spatial and temporal resolution. It allows detailed studies of atmospheric flow features such as blocks or cyclones.

Satellite and Reanalysis Dataset Dependence of ETCCDI Extreme Precipitation Trends in Paraná, Southern Brazil

International Journal of Climatology, EarlyView.
Extreme precipitation trends detected in Paraná, Southern Brazil (1983–2024), are strongly conditioned by the dataset used, with reanalyses indicating coherent inland drying and longer dry spells, observations retaining stronger mesoscale heterogeneity, and satellite products often showing declines in short‐duration extremes. Monthly diagnostics reveal

Validación de la asimilación de carbono a través de la producción primaria bruta (PPB) estimada mediante teledetección en dos ecosistemas del Parque Nacional de Doñana: marisma estacional y matorrales mediterráneos xerófilos

Revista de Teledetección
El Parque Nacional de Doñana, situado en el suroeste de la Península Ibérica, se enfrenta a unos desafíos ambientales sustanciales, con eventos extremos de sequía cada vez más frecuentes y un papel clave como hotspotde biodiversidad. La comprensión de la

Multi‐Timescale Drought Evolution in Greece (1960–2022) From Station‐Based SPI and SPEI

International Journal of Climatology, EarlyView.
Using homogenized data from 67 HNMS stations in Greece (1960–2022), we calculated SPI and SPEI at 1–12‐month scales to characterize meteorological to hydrological drought. We quantified the network‐based spatial extent of drought, compared SPI and SPEI drought signals, and tested changes with autocorrelation‐robust Mann–Kendall trends and Pettitt ...

Spatial model of the Trooz Glacier dynamics based on meteorological data from the Akademik Vernadsky station

Український антарктичний журнал
This paper models the dynamics of the Trooz Glacier, Antarctic Peninsula. To integrate remote and meteorological data, we processed ice flow velocities derived from satellite radar imagery, air temperature, and precipitation obtained from the ERA5 ...

Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

International Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

Climatology of Tropical Cyclones Approaching Tanzania and Their Impacts on Rainfall in East Africa

International Journal of Climatology, EarlyView.
Tropical cyclones (TCs) that approach Tanzania bring heavy rainfall over northern Mozambique, Tanzania, and south‐central Kenya, but the occurrence of these TCs reduces precipitation over southern African countries. Easterly steering winds and the Mascarene High are key features directing TCs westward.

Contrasting Heatwave Regimes in Dry and Humid Subtropical Mexico: A Station‐Based Probabilistic Assessment

International Journal of Climatology, EarlyView.
Heatwaves have intensified under a warming climate, producing substantial environmental and societal impacts. This study characterizes heatwave regimes in two contrasting regions of Mexico using a percentile‐based threshold and a Poisson distribution framework.
