Assessing Past and Future Temperature‐ and Precipitation‐Based Indicators in the Republic of Yemen

International Journal of Climatology, EarlyView.
For the first time in the literature, this work assesses the past and future climatic trends over Yemen, a highly vulnerable country for which science‐based, high‐quality information for the development of climate change adaptation plans was not available until now.

Factors controlling threshold friction velocities in semi-arid areas of the United States

, 1997
A physical model was developed to explain threshold friction velocities u*t for particles of the size 60–120 μm lying on a rough surface in loose soils for semiarid and arid parts of the United States. The model corrected for the effect of momentum absorption by the nonerodible roughness.

Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires

International Journal of Climatology, EarlyView.
Extreme wildfires in the Pantanal in 2024 were driven by a cascade of heatwaves, rainfall deficits and the absence of the annual flood pulse. These conditions dried soils and rivers, enhanced fuel accumulation and enabled early and intense fire outbreaks.

Projected Evolution of Climatic Aridity in Spain: Robust Signals and Model Uncertainties

International Journal of Climatology, EarlyView.
This study examines the projected evolution of climatic aridity in Spain throughout the 21st century, using the UNEP Aridity Index and CMIP6 simulations under different emission scenarios and global warming levels. Despite model biases, results show a general increase in aridity across the country, particularly in southern regions and the Canary ...

Precipitation regime drives key alterations in subtropical stream fish community assembly and functional trait distribution across a major rainfall gradient

Journal of Freshwater Ecology
Shifting precipitation patterns associated with global climate change are significantly impacting lotic ecosystems worldwide. To understand how these changes influence stream fish community assembly, we conducted a space-for-time study under a steep ...

Spatiotemporal Droughts Propagation and Direct Driving Variables Under Climate Change Projections: A Case Study of Tunisia

International Journal of Climatology, EarlyView.
Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under

Variability of the Climate in Athens‐Greece Over the Last 165 Years of the Period 1858–2023: An Assessment Based on Thornthwaite's Climate Classification and Relevant Indices

International Journal of Climatology, EarlyView.
Athens' climate according to Thorthwaite is stable despite warming trends. Athens' climate remains semi‐arid and mesothermal over 165 years. Strong increases in evapotranspiration and stable precipitation were found. Soil water storage capacity affects water deficits but not aridity type.

Global Patterns of Critical Soil Moisture and Seasonal Hydrological Regimes Derived From Soil Moisture and Diurnal Soil Temperature Range

Water Resources Research
The global distribution of hydrological regimes determines land‐atmosphere feedbacks by regulating the water, energy and carbon fluxes. Strong land‐atmosphere feedbacks are observed over the drier surface where evapotranspiration and partitioning of ...

Projected Intensification of Hydroclimatic Extremes in Rio Grande do Norte, Brazil, Under CMIP6 Scenarios

International Journal of Climatology, EarlyView.
The graphical abstract presents observed (1963–2023) and projected changes in hydroclimatic extremes in Rio Grande do Norte, Brazil. It integrates dry‐spell duration (CDD) and extreme precipitation (R95pTOT) using CMIP6 multimodel ensembles under SSP1‐2.6, SSP2‐4.5, and SSP5‐8.5.

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and
