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 ...

Planktic foraminiferal distribution across the Cretaceous–Paleogene (K–Pg) boundary from the Neuquén Basin (Cerro Azul section): biostratigraphy and paleoenvironmental significance [PDF]

Journal of Micropalaeontology
The Maastrichtian–Danian time interval corresponds to one of the largest mass extinctions in the Earth's geological history. We investigate changes in planktic foraminiferal assemblages and TEX86H-based sea surface temperatures (SSTs), which reflect ...

Shifting Patterns of Precipitation Extremes in the Southeast Atlantic Basin—Brazil: From Observed Trends to Future Projections

International Journal of Climatology, EarlyView.
Observed trends and EC‐Earth3 climate model projections demonstrate expressive changes in the Southeast Atlantic Hydrographic Basin, Brazil. Significant increases in rainfall intensity and dry spell duration in the present climate are followed by projected amplification of extreme precipitation under future warming, particularly under the SSP5‐8.5 ...

The use of planktonic foraminifera transfer function and Hill sigmoidal fit to reconstruct upper ocean thermal stratification

Frontiers in Earth Science
Planktonic foraminifera assemblages have been extensively used to reconstruct paleotemperatures along the Quaternary. Most of reconstructions focused on surface temperature or in a specific water depth.

Preferential Loss of High Trace Element Bearing Inner Calcite in Foraminifera During Physical and Chemical Cleaning

Geochemistry, Geophysics, Geosystems, 2021
Trace elements (TEs) in the calcite shells of foraminifera are widely used in paleoceanographic reconstructions. Nearly all TE analytical protocols include cleaning to remove contaminant phases.

Characteristics of Boundary Layer Height Variations in Global Arid Regions and Their Sensitivity to Influencing Energy Factors

International Journal of Climatology, EarlyView.
Global warming has intensified drought impacts across most arid regions, altering surface energy partitioning and atmospheric boundary layer (ABL) development. Using 1979–2018 ERA‐Interim reanalysis data, we show that the long‐term mean boundary layer height (BLH) over global arid regions is approximately 841.8 m, nearly 200 m higher than over humid ...
