A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

International Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

Comparative Analysis of Satellite-Based Rainfall Products for Drought Assessment in a Data-Poor Region

Hydrology
Drought is one of the most impactful natural disasters, and it significantly impacts three main sectors of a country: the environment, society, and the economy.

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Sensitivity of Consecutive‐Dry‐Day Trends to Trace Loss in Matched Precipitation Archives

International Journal of Climatology, EarlyView.
Loss of trace precipitation information can turn valid dry days into missing observations that interrupt consecutive dry day (CDD) spells. Simulating this loss reduced the median cross‐archive CDD trend discrepancy by 88% across 205 matched Spanish station pairs; a separate global experiment converting documented traces to missing observations changed ...

Investigating the Impact of El Niño–Southern Oscillation on Rangeland Productivity in the Limpopo Province, South Africa

International Journal of Climatology, EarlyView.
This study investigated ENSO effects on rainfall variability and rangeland productivity across Limpopo Province, South Africa, using DMP and ONI data for 1999–2024. Productivity was higher in eastern and southern regions and lower in northern and western regions.

Added Value of CESM‐Driven WRF for Mean and Extreme Precipitation Over Complex Terrain in Southwest Asia

International Journal of Climatology, EarlyView.
Southwest Asia remains understudied in high‐resolution regional climate modelling despite its climatic sensitivity and complex orography. We compare WRF (10 km), CESM (~2°), and ERA5 (0.25°) for 1950–2002, with supplementary validation against CHIRPS and PERSIANN‐CDR. WRF corrects the unrealistic summer precipitation overestimation of CESM and improves

Assessment of the Exposure of Australia to Tropical Cyclones Through a Climatological Model for Cyclone Weather Extent

International Journal of Climatology, EarlyView.
Australia has different levels of exposure to tropical cyclones. Using historical records, this study investigates the spatial variability of tropical cyclone formation across the Southeast Indian–South Pacific basin, quantifies the exposure of different parts of Australia to tropical cyclone weather events, and examines decadal variability in cyclone ...

Short‐Term Agricultural Drought Prediction Using Explainable Data‐Driven Models and Quantified Uncertainty

International Journal of Climatology, EarlyView.
This study demonstrates that explainable deep learning models can skilfully predict short‐term agricultural drought using standardized drought indices, capturing hydroclimatic memory and seasonal persistence. The integration of uncertainty quantification and SHAP‐based interpretability reveals the dominant role of antecedent moisture and climate ...

Beyond ENSO: Temperature, Rainfall Variability and Emerging Climate Risks in Belize

International Journal of Climatology, EarlyView.
This study analyses 50 years (1975–2024) of Belize's climate data to evaluate ENSO's influence. Results show negligible ENSO impact on rainfall but a moderate signal in nighttime dry‐season temperatures, with El Niño years 0.5°C–1.0°C warmer than La Niña years.

Spatio‐Temporal Assessment of the Complementarity Between Hydroelectric, Wind and Solar Energy Sources for Northeastern Brazil

International Journal of Climatology, EarlyView.
Using 24 years of climate and hydrological data, this study quantifies the spatiotemporal complementarity among the water availability of the Sobradinho reservoir, wind and solar in Northeastern Brazil. The integration of hierarchical clustering and compromise programming reveals how seasonal variability and reservoir dynamics interact with atmospheric
